[DUAL GPU SYSTEMS] Performance Issues and Troubleshooting

[elder smelt]

could you return it still?

[tidal finch]

Well it does have a disclaimer about HDR. Maybe it's too obscure

[humble frigate]

bought used ^^

[onyx warren]

1998

2000

[elder smelt]

for how much?

[versed knoll]

HDR is one of the notes in the spreadsheet

[humble frigate]

4k turns it way down again

and not saying its anyone's fault, sorry if it came out like that. just disappointed 😛

[humble frigate]

55 euro

[elder smelt]

ok not too bad

maybe you can use it for something

[tidal finch]

Paper weight

[elder smelt]

😭

[humble frigate]

i have a wife and kids who games at 2k or less. maybe they want some generated frames 😛

[rain hull]

77x2 at 1440p with HDR makes sense for an rx6400. So it's just worse than expected for 4k

[elder smelt]

there we go

not a waste after all

[rain hull]

Lol

[rain hull]

BTW what did it drop to at 4k?

With SDR

Was it something like 35x2 or 40x2?

[humble frigate]

52x2

[rain hull]

100% res scale?

[humble frigate]

yes

[rain hull]

That's actually pretty decent

[humble frigate]

and 1 frame latency

[rain hull]

I'll put it in the chart when I get the time

[humble frigate]

well my 3080ti alone does 89 😅

so maybe for some lower cards its ok?

[versed knoll]

The RX 6400 is an absolute unit, just not one for 4k

[tidal finch]

Only in this server someone would mention "absolute unit" and "RX6400" unironically in the same sentence 😆

[humble frigate]

hows the RX6600? using it for 4k?

[versed knoll]

"RX 6500 Xt my beloved"

⚰️

[onyx warren]

Yes, 4K 60/120 no problem.
My max was 120/240 or 60/480 at 25% Res scale

[elder smelt]

bro I hope the 6600xt won't be an issue 🙏

cheapest I could find it at

[humble frigate]

What psu you running? Only have a 850, afraid I might need more juice

[elder smelt]

nah your good

you are meant to undervolt the cards

[humble frigate]

If only I could find my cables then 😅

[elder smelt]

my 1070 used 60w when used for lsfg and undervolted

[versed knoll]

My RTX 3060 12GB + RX 6600M + Ryzen 5 5500 are all undervolted and in total consume like 220W average

[elder smelt]

thats really efficient

uses less than my primary card 😅

[tidal finch]

Wow, that is impressive

[onyx warren]

850 as well

I'm sure I never use more than 500-600 with a 3070 Ti

[versed knoll]

Because of these I feel like my 750W PSU was overkill lol

[tidal finch]

170 -> 130 is insane on that 3060

[elder smelt]

better safe than sorry

[versed knoll]

Yeah that was my thought process

[versed knoll]

I spent a while fine tuning the undervolt on it, I got a satisfying result

[elder smelt]

its not like psus are expensive either

[versed knoll]

Mine costed me 55 dollars

It's an xpg pylon

[elder smelt]

bronze rated?

[versed knoll]

Yes

[elder smelt]

well its not the best but its good you went for a 750w instead of something less

I think mine was like 150 ish in terms of usd

850w platinum

its nice to be worry free I guess

[tidal finch]

Bigger psu is almost always nice since they don't use the fan if components draw below a certain threshold. So it doesn't get clogged with dust years after.

[elder smelt]

I don't think my psu fan has ever spun lol

or I can't hear it

[tidal finch]

Yeah I have a 600W one and I already changed it's fan once 😆

[elder smelt]

damn

[humble frigate]

I have tried to undervolt but my card ain't having it. But why would I undervolt it? Have I misunderstood the intention of LS. I thought if I could generate 80 fps without ls I could turn up the eye candy limit it to 60 fps and then generate 60 more using LS and another GPU.

[elder smelt]

you lose nothing when you undervolt and you keep the power cost low

means less strain for the psu and less heat generated

performance can even be improved if undervolted and overclocked at the same time

[humble frigate]

I have tried over and over. Must be doing something wrong. Eventually when gaming it just crashes on me.

[elder smelt]

might be too extreme of an undervolt

[rain hull]

My B570 uses 60w when used for LSFG when stock (attempting to undervolt severely corrupted drivers)

[elder smelt]

wth corrupted the drivers?

60w is really good for stock though

[onyx warren]

The rx6600 uses like 50w

[versed knoll]

100% usage though?

[onyx warren]

No, when I use it for 4K120 like usual

Like 65-75%

[versed knoll]

Yeah lower usage means less wattage

My RX 6600M is very harshly undervolted and 58W is the most it draws

[onyx warren]

I didn't undervolt the RX6600 at all, 50W for normal usage is completely fine for me

[versed knoll]

Yeah that's great

I'm just saying we are talking about full load

[humble frigate]

@onyx warren just be clear, its 6600 not 6600 xt right? also do you use HDR?

[onyx warren]

Yes and no

But it should easily be able to do 4K 60/120 even with 25% less performance from the HDR

[humble frigate]

Okay Thanks. It costs 3-4 times more than the 6400. Need to think about it a bit 😅

[elder smelt]

4 times!?

no way

[humble frigate]

i paid 55 euro for the 6400 and the 6600 is 214 euro

is my math off?

[elder smelt]

2nd hand 6600?

[onyx warren]

I got one for 150€ used

[elder smelt]

I got a 6600xt used for around 150 too

[onyx warren]

And a 6400 would've run me almost 100€ used

[elder smelt]

prices differ a lot in regions huh

but no way a 6600 should be bought at $200 imo

[humble frigate]

There's no second hand in my region 😅 not atm anyway. eBay is as expensive as new

[elder smelt]

are there any other cards 2nd hand in your region?

e.g rx 6700

[onyx warren]

4090s rn I bet

[elder smelt]

might be cheaper than that 6600

[humble frigate]

Yeah and they cost more than when they were bought 😅 people think they got pure gold in their hands

[elder smelt]

the market is so stupid lol

[humble frigate]

Rx5700 xt

Rx 6500 xt

[versed knoll]

What about the RX 5600/5700 XT?

[elder smelt]

its a good choice

stronger than the 6600

[humble frigate]

135 euro

[versed knoll]

Yeah, like 30% better iirc

What about an RX 5600 XT?

[elder smelt]

you should be able to find cheaper ngl

where do you live?

[humble frigate]

Denmark

[elder smelt]

I see

[versed knoll]

.

[humble frigate]

108 euro

[versed knoll]

Alright, the 5700 xt offers a great uplift for that extra you would pay for it

[elder smelt]

5600xt is cutting it too close imo aim for something higer

[onyx warren]

5700XT for 135€ is a steal imo

[versed knoll]

Yes but imagine the 5600 xt costs 60 euros

[elder smelt]

yea no idea why it costs so much in his area

[onyx warren]

Is your 4K120 screen connected with DP or HDMI?

[elder smelt]

a 6600xt costs around 130-160 euros here if I convert it

insane pricing

[humble frigate]

HDMI

[onyx warren]

Then you'll need at least a 6600 anyways

For HDMI 2.1

[versed knoll]

An RX 5600 XT is a great option when it costs way less than a 5700 XT

This isn't the case so it's better to just get a 5700 xt

[elder smelt]

what about the normal 5700?

[humble frigate]

Denmark has some of the craziest taxes. You know the tarifs trump talks about. That is our everyday for everything.

[onyx warren]

5000 series don't have HDMI 2.1 and neither the 6000 series below the 6600

[elder smelt]

that sucks rip

[versed knoll]

I never tried the normal 5700 for LSFG, I just know my brother has it and it runs well, should be only like 12% behind a 5700 xt

But people love to price the rx 5700 as if it were the xt

[elder smelt]

its less than 12%

its like on par even

with the bios flash

[humble frigate]

So also 6400 fails in that field? 😅

[elder smelt]

it would be interesting to see benchmarks for it with lsfg

[versed knoll]

European tariffs are something else, it's dumb

[onyx warren]

Yes, you could only output 4K60 with that one

That's why I went with the 6600 in the first place.
Cheapest card with hdmi 2.1 that works for 4K120 lsfg

[versed knoll]

DisplayPort my beloved

[elder smelt]

this

[onyx warren]

A lot of TVs still don't have it

[elder smelt]

smh

[onyx warren]

4 HDMI ports and that's it

[versed knoll]

My chinese monitor does

[onyx warren]

Monitors and TVs are very different

[elder smelt]

hdmi to dp adapters still suck right?

[onyx warren]

Oh yes

[humble frigate]

Oh wow, I really screwed up on that one. At least the wife seems interested in generating some frames. Guess Sims at 240 is something 😅

[elder smelt]

lucky that you managed to find something for it to do atleast

[onyx warren]

I had to get one for my rx6600 since it only has one HDMI port and that is reserved for my TV

And my 3rd monitor is so old that it only has HDMI and DVI

[elder smelt]

truly a based 6600

[rain hull]

6400 has HDMI 2.1 and DisplayPort 1.4.

[onyx warren]

I researched before I got one and didn't find one that had hdmi 2.1

[onyx warren]

Wait no, I think it was because they all just had 2 outputs and I have 3 monitors

That was the problem

[versed knoll]

Bro casually gaslit everyone and we fell for it ⚰️

[onyx warren]

https://tenor.com/view/shannon-sharpe-suit-meme-man-wearing-suit-meme-suit-slideshow-sparkles-and-champagne-gif-26378137

[elder smelt]

🍷

[humble frigate]

oh good. thought i did my research on the HDMI. put wouldnt be the first time i was wrong today 😛

[humble frigate]

If i could get a 4080 at the same price as a RX660 would that be worth it? then my 3080 ti would become the second gpu ofc. but generally amd is better as a secondary right?

[onyx warren]

What kinda question is that

Are we supposed to say no?

[tidal finch]

In what universe are you finding 4080 that costs the same as rx 6600 😆

[versed knoll]

I like AMD but not even RX 6600 for 200 bucks vs RTX 3060 12GB for 160 bucks comes close to how much of an overwhelmingly obvious choice this is

[elder smelt]

hard choice

[humble frigate]

i dont know what to say man 😛 i dont make the used market around here. i just saw it and went "wouldnt this be better, and for the same price"

[elder smelt]

if its somehow real I would be on that in a nanosecond

[humble frigate]

ill give it a go. looking at the other listings from that person it seems fishy. but they live kinda close, so could just ask for meet up.

[tidal finch]

Yeah there is no chance. Must be broken or something

Even then people want more than RX 6600 😆

[clear roost]

Hey, I just wanted to double check with dc before buying

Monitor: WQHD/240hz
Mobo: b650 tomahawk wifi that has 2x 4.0 pcie that is shared with m2 (only impacts two way speed of SSD as I understand)

Will RX6400 for 1440p work? From what I've seen it's 14-15% slower on pcie 3.0 4x (4.0 2x)

[clear roost]

I found used RX6600 for 90$

[onyx warren]

Should work fine if 4.0 x2 works the same as 3.0 x4

[versed knoll]

X2 as in 2 pcie lanes?

Sounds daring, my recommendation is making sure you can return it if the thing doesn't work

[versed knoll]

I got a used rx 5700 for 90$

[clear roost]

specs from msi

Doesn't make much sense (cuz it's already 2x) but from what I understand SSD uses both ways while GPU uses one way, so it will only negatively impact my SSD (which is nowhere those speeds anyway)

[tidal finch]

Wow MSI really went for that 4¢ savings with this

I'd test that scenario before buying anything. @clear roost

[elder smelt]

flexing now are we?

[tidal finch]

You're not only gonna gimp your 2nd gpu but your ssd as well which sucks

[versed knoll]

Yes

Flex your best purchase in value for moeny

[versed knoll]

Some GPU's suffer from having less lanes even if they get nice bandwidth from running on pcie 4.0

[elder smelt]

yea that's difficult for me 😭

5700x3d for around 120 usd was good

[versed knoll]

Based

My best is the legendary 65 usd 5600 xt that was like new

[elder smelt]

🙏

[versed knoll]

You have ascended

[elder smelt]

I just hope it works without issues

then I will truly ascend

👀

crazy fps

[versed knoll]

Get those spreadsheet numbers please

[elder smelt]

my resolution isn't on there 😅

I need to get a generic undervolt for it too first

got to minmax

[versed knoll]

What's your resolution?

[elder smelt]

3440x1440

[versed knoll]

Hmm, are you unable to set it to 2560x1440p?

[elder smelt]

I'll try to

so I just 2x my base fps

and see how much it can do

on stock settings

hmm what game

hmmmm

why is it like capped?

it only goes as far as my max refresh rate

its doing 330fps but it can do more if I could uncap it

[versed knoll]

Base FPS cap out at your refresh rate

LSFG can't capture beyond that

[elder smelt]

rip

it can go beyond 330fps that was said on the chart

its doing it easily

[versed knoll]

what's your refresh rate?

[elder smelt]

165hz

so double that

[versed knoll]

take a screenshot with usage numbers

[elder smelt]

it went to 350 for a split second

if only I could uncap it 😔

[versed knoll]

Is this 2560x1440p?

[elder smelt]

yes

you want me to try my resolution?

3440x1440?

[versed knoll]

Nah it's fine

[elder smelt]

my res 💀

[versed knoll]

If you are at 165/330 with 93% usage, then I guess it's fine to assume the limit is somewhere between 340 and 350

[elder smelt]

its still doing 330

maybe it was 3440x1440 after all

[versed knoll]

anyways

[elder smelt]

I'll try changing it to 1440p on windows

[versed knoll]

@rain hull

[elder smelt]

its far stronger than what the chart said

[versed knoll]

the rx 6600 xt is still proving to be on a different league

[versed knoll]

more than once we scratched our heads about it

Because my RX 6600(and the M)'s only did 115/230

[versed knoll]

What's the second PCIE slot?

[elder smelt]

gen 3 x8

my main gpu is the same

[versed knoll]

interesting, are you able to change the lanes on bios?

Say, 3.0 x4?

[elder smelt]

ehh probably?

you want more data?

[versed knoll]

I just want to find out why is the RX 6600 XT so many leagues ahead

Compared to the two RX 6600's I tested

[elder smelt]

yea its an incredible difference

[versed knoll]

Could be physical slot size, could be bandwidth, or could be a combination of that added to the fact it's an rx 6600 xt

But my processor only allows pcie 3.0 so I can't test 4.0 vs 3.0 and compare the loss of performance

[elder smelt]

same

[versed knoll]

but 3.0 x8 vs 3.0 x4 would make an interesting test

[elder smelt]

I'm very limited but it works

lemme go and check

So after testing the 6600xt I can confirm that nvidia sucks for dual gpus imo

Atleast mix with amd being render

So many issues it was unreal

[versed knoll]

Tell me something new

[elder smelt]

I think its x4 now

Time to check

Amd control panel with 2 gpus is seamless

Crazy stuff

[versed knoll]

I can set my RTX 3060 that's on my main slot to be the LSFG GPU with pcie 3.0 x16 lanes

When I did it could only do 100/200 fps on X2 at 1440p

t-r-a-s-h

[elder smelt]

😭

[versed knoll]

Meanwhile my RX 6600M that was running on pcie 3.0 x4 could do 115/230

[elder smelt]

Never mind still on x8

Stupid bios

[elder smelt]

Nvidia overhead moment

Yea idk

I don't think I can x4 it

nevermind

huhhhhhhh

why the hell is my main gpu x4 but not the 6600xt

[versed knoll]

what does gpu z say?

[elder smelt]

this

braindead bios

[versed knoll]

extremely cursed

check the bifurcation settings if you changed something there

[elder smelt]

Theres no bifurcation settings

Its auto pretty much

[onyx warren]

Power to LS

[elder smelt]

Unless i move the card to main slot this ain't happening

Poor pc is struggling as is 😭

Barely fit this big boy in

Its bigger than my main gpu

[versed knoll]

Oh well, it's not that important

[elder smelt]

either way I'm real impressed by this card

omg wait

lemme redo the test

yep my ls settings were reset 💀

actual real numbers now

doesn't make a difference in 1440p but for my native res it should be much less now

[versed knoll]

What changed?

[elder smelt]

res scale 😅

still the same 1440p numbers though

it can go further than that

but my native res should change now

I'm bottlenecked here

pcie?

render gpu can't push out any more frames at that point

but with a lower res scale it can do my refresh rate 2x

and render gpu can push out 20 more fps

@rain hull it is confirmed that the 6600xt can do 330fps on 1440p but I think it can go further than that if I wasn't refresh rate bottlenecked and pcie bottlenecked too

[onyx warren]

Can't you unlock the rr?

[elder smelt]

apparently its capped by my monitor's rr

ls won't capture any more frames than that

[onyx warren]

It did for me

[elder smelt]

how did you do it?

[onyx warren]

I didn't do anything special

Just have sync mode on Off and then it should work

[elder smelt]

already off for me

[onyx warren]

Weird

I mean it wouldn't do much more anyways, you're at 95% usage

This is pretty much the highest stable rate you're gonna get

[elder smelt]

true I'd guess like 10 more fps probably at most

[elder smelt]

yup

[onyx warren]

And then it would be unstable anyways

[elder smelt]

maybe but I can't test it

now I have to undervolt

49w stable 👀

[onyx warren]

Undervolted my 6600 yesterday, first thing my PC did was crash

[elder smelt]

rip

[onyx warren]

But got a stable one now

[elder smelt]

how did you undervolt?

[onyx warren]

I think I put it to 1080mV

[elder smelt]

whats the default?

[onyx warren]

And the clocks like 2200 min and 2700 max

[elder smelt]

1150?

[onyx warren]

1150

1055 was crashing

[elder smelt]

I guess I'll push mine lower

only 1100 rn

1080 seems stable

1065 = crash

1070 seems stable

[elder smelt]

it may look like I need to do the flexi fix 🥲

[onyx warren]

https://tenor.com/view/understandable-have-nice-day-have-a-great-day-have-a-good-day-nice-gif-20850110

[rain hull]

Yea, estimates on the chart

Look at the LSFG 2 section of it, it's safe to say that I rounded down

[rain hull]

Damn

[elder smelt]

dw about those results

[rain hull]

I'd give higher multipliers and VSR a try

[elder smelt]

My ls settings got screwed with but later got it fixed

[rain hull]

Wdym

Low res scale or smth?

[elder smelt]

Yep

But i tested at 100 later

[rain hull]

Ah

[elder smelt]

A bit higher up

It might do like 340 or even 350 fps at 1440p but I'm pcie bottlenecked i think

And refresh rate locked too

[rain hull]

I believe the previous person to test it was also limited by a 165hz monitor

A750 results too, it was just barely refresh rate limited so I marked it as an estimate and rounded up a little

[elder smelt]

Goes to show how strong they are for lsfg

[rain hull]

That aside, does it work well in games?

Any odd perf hit from outputting from the 6600xt or activating LS?

[elder smelt]

Yes but I think I have the flexi bug too

Reinstalling rn

[elder smelt]

It did

But it wasn't the same as the 1070

[rain hull]

Which one

Issues with or without LS

[elder smelt]

Both

So reinstalling w11

[rain hull]

Summarize

[elder smelt]

So I lose fps even without ls like last time and when I use ls, I lost even more fps

It didn't seem hardware related so I'm doing software rn

But if it doesn't work I will 100% know what's doing it and fix it

I have an idea...

[rain hull]

Like a hard cap or percentage worse FPS? Was the render GPU using lower wattage?

[elder smelt]

Not a cap but general worse fps

It might be because of my pcie layout of my devices tbh

If it is I'll move my stuff

[rain hull]

Yea that would make sense

I have similar issues when I enable low latency mode in nvcp

So it can be software

[elder smelt]

Yea same mindset

I'll clear software rn then see if it works

[onyx warren]

Just made a comparison to stock, undervolting doesn't even drop a single Watt in normal usage

[mental peak]

So I got my 4060, went through the dual gpu setup guide and got it working. My problem is that while running the same config in games and in ls, didn't change any settings anywhere, I'm getting a lot of frame drops and stutters. But both GPUs, the 4070 for graphics hovers around 70% and the 4060 around 50% usage in helldivers 2.
At 1440p, x3 from 46 fps scale at 70, ls1 performance and scaling factor at 1.3.
Those exact settings worked perfectly on the 4070 alone, but they don't on the 4060, even lowering them doesn't fix the stutters. Same problem in god of war ragnarok.

This is my motherboard for dual GPU

[brave mesa]

Chad

[elder smelt]

yea no idea whats going on

I'll try to retrace my steps then

[onyx warren]

Try disabling resizable bar in bios

[neon sleet]

and HAGS

[mental peak]

It was already disabled apparently

[mental peak]

After disabling it, it gives me either a black screen when enabling ls or puts back to the desktop screen
Edit: forget that, my game was fullscreen XD

[rain hull]

Reset NVCP settings

[versed knoll]

Mine is running 912 mv

[elder smelt]

@rain hull I think I solved the fps drop without ls

but the ls one still happens

wait I think I kinda fixed it a bit

[versed knoll]

You ~ fixed it

[elder smelt]

I wish

[humble frigate]

Thanks for the support earlier this week everyone. Now I got this 😀

[versed knoll]

Excellent choice

[humble frigate]

Thanks 😀
Unfortunately I just can't find my psu cables. Seasonic shipped me some new ones but wont arrive until Monday.

[versed knoll]

Just to make sure, @elder smelt @onyx warren you both are using Windows 11 right?

[elder smelt]

I am

[rain hull]

Make sure they're compatible with your PSU

Cables from different PSU models are often wired differently, and mixing them up can fry your PC

[humble frigate]

Yeah that's why I wrote directly to seasonic 😀

[versed knoll]

Alright

I stubbornly run Windows 10 with the same install since 2020 and haven't ran into that gradual performance loss thing yet

[elder smelt]

you got it in w11?

[versed knoll]

I haven't tried Windows 11 on my desktop PC

But I have yet to see someone that uses Windows 10 get that issue you and Flexi had

[elder smelt]

hmm

most people use w11 now so maybe thats why

still I can't tell if this is software or a pcie bottleneck

installing the amd chipset made my performance much better but its not the best it was like before

[onyx warren]

Jesus

[onyx warren]

Yes

[cobalt cedar]

Amd has to pay the dev of this amazing tool. Finally giving folks an actual good reason to buy their goofy aah graphic cards.

[versed knoll]

The RX 6600 was already a banger even before LS

But I agree for the rx 6400 and the 6500 xt

Cards no one wanted but now plenty want

[cobalt cedar]

Those were pretty much ewaste until now

[brave mesa]

And who gonna try 9070xtx

[rain hull]

I'm going to assume it'll be powerful enough for framegen that testing it will be impossible due to LS not being able to capture beyond refresh rate

Except for maybe 4k240 or 4k360

E.g, on a 165hz screen your testing is limited to 165x2

[brave mesa]

Yeah

4k 240hz

Or 5kx2k

You know those ultra wide

[rain hull]

Someone (Dranas) tested the 7900xtx and 4080 and the 7900xtx was a good 20% more capable, but they had to use multipliers above X2 because they were refresh rate limited

So I couldn't put it on the chart 🥲

[brave mesa]

So for lossless scaling 7900xtx was around 20% faster than 4080?

We know AMD is faster for frame gen than NVIDIA. But it's it the case also in 5000 series?

Or NVIDIA did something to improve this type of calculations

[rain hull]

No idea

[brave mesa]

I've been busy lately as you might have noticed. Got heavy works to do

🤯

So I didn't catch up with hardware news for the past 2 weeks

[elder smelt]

Ok I think I may be pcie bottlenecked ngl

there is some kind of really weird overhead

@clear sundial did you ever have less framerates on dual gpus before you went to pcie 4?

Hmm if there is some kind of overhead and its not from pcie, what would it even come from? I have to brainstorm 🤔

it looks like a cpu bottleneck but isn't specifically one

maybe ram related too

[versed knoll]

Don't go off by CPU usage, check usage of both GPU's

[elder smelt]

yea my gpu usage gets lower

I never check cpu usage because its always low

but my fps takes a hit

looks like a cpu bottleneck but it isn't one

[clear sundial]

PCI-E 4.0 to PCI-E 3.0 was always a performance drop for me on dual GPU (x8 CPU) on the LSFG GPU.

On the main card, not really an issue. I didn't even feel a difference going from PCI 4.0 x8 to PCI 4.0 x16 or vice-versa

PCI 4.0 x8 (CPU) to PCI 4.0 x4 (Chipset) was a massive drop in performance in both LSFG GPU and main GPU

[rain hull]

I had similar jank from having low latency mode enabled

[elder smelt]

I'm pretty sure I got everything disabled in my control panel unless its doing similar behaviour without a setting

[elder smelt]

so gen 3 x8 vs gen 4 x8 always has less performance?

[rain hull]

3.0 x8 second GPU, 4.0 x4 render GPU, around a 60fps base I see basically 0 hit on base FPS or frametimes outputting from my B570, and CPU usage is placebo range, maybe lower

[elder smelt]

so technically we have the same bandwidth

[rain hull]

I'm at 1440p 16x9, you?

[elder smelt]

ah

im at 3440x1440

[rain hull]

Try forcing 16x9

See if it helps, just for testing

[elder smelt]

alright

also

would ram be an issue in transferring data like this?

[rain hull]

Potentially, video copies through RAM, but RAM bandwidth significantly exceeds PCIe bandwidth so it shouldn't be a limit unless you're running PCIe 5.0 x16 with a single DDR4 stick

[elder smelt]

I'll keep that in mind because my ram setup is very goofy

also also

low latency mode changes what?

if its buffer frames maybe I need to change the default amount of frames my gpu buffers

[clear sundial]

For me yes, but I do suspect it being the 4060 ti's fault. I didn't test with another GPU yet

And this is also on 4K. 1440p should be easy to drive in comparison

[elder smelt]

4k oh

how much performance loss are we talking?

3440x1440 is nearly half of 4k so it shouldn't be too bad

[clear sundial]

Around 33% #1328337747399938138 message see here

146 fps -> 109 fps

[elder smelt]

ok it does help a lot but it still does a hit

pcie issue here?

and I'm talking about when using lsfg

without lsfg, performance might get worse in some cases still though

[brave mesa]

ofc

[elder smelt]

😭

a game could be running like 100fps with single gpu or display gpu being render too but as I use a secondary card as display it drops to 80s or 90s

[brave mesa]

dam

sad

[elder smelt]

yep

it can even go high 70s

it could be pcie but it might be more than that

I'm not sure

[brave mesa]

so dual gpus is not perfect in the end

sad, i fear i wont achieve my 100.00% stable framerate/frametime with 5090/7800xt 5k 240hz

using dual mode

[elder smelt]

for me yea but for others they seem fine

[brave mesa]

oh nice

but not nice for u xD

[elder smelt]

[brave mesa]

rofl

nah man, who will be with me here if u go that route

[elder smelt]

I'm sure we got some great minds here in general chat

[versed knoll]

It's perfect for me

Maybe because I'm using an AMD gpu

[brave mesa]

u special my man

u are the OP ( over powered ) bush

[elder smelt]

both my gpus are amd but here I am 😭

[elder smelt]

this^

[versed knoll]

Whenever I try to test my 3060 for LSFG it just becomes hyper jank

You can tell from Ravenger's notes on it in the chart that none of us is happy with the results it gave

[elder smelt]

yea I saw those lol

really stupid

[brave mesa]

so basically 2 diff gpus it sucks

same gpu brand it fine

[elder smelt]

no

[brave mesa]

oh?

[elder smelt]

nvidia + amd is good

[brave mesa]

perfect

[elder smelt]

example here without lsfg

usually I can hit 175fps

but it got lowered

due to some kind of overhead

if its with lsfg 💀

[versed knoll]

nein

I'm using RTX 3060 12GB + RX 6600M

[elder smelt]

this is the cpu bottleneck looking thing I was talking about

[versed knoll]

No LSFG

LSFG X2

[elder smelt]

looks really great for you

[versed knoll]

What game is that?

[elder smelt]

no lsfg

with lsfg 2x

[brave mesa]

NEIN?!!! WARUMMMM

[elder smelt]

7days to die

[versed knoll]

This screams CPU bottleneck to me, what's your current CPU?

[brave mesa]

ICH HEAR EIN DEUTCHEN PERSONEN SPRECHE

[elder smelt]

5700x3d

but it isn't

it shouldn't be

[versed knoll]

Also check with task manager if you have windows doing anything dumb on the background

[elder smelt]

usually its fine without secondary gpu

[brave mesa]

my 18 time speaker stuck on screen and it appeared in a weird position in ur text

[versed knoll]

One time I was getting CPU bottlenecked quickly with LSFG enabled because Windows 10 was doing a background scan

and it took 20% of my CPU

[elder smelt]

background scan? tf

[versed knoll]

Malware scan

[elder smelt]

my cpu usage is less than 40%

[versed knoll]

Windows defender jank

[elder smelt]

disable that crap

[brave mesa]

u have that enabled?

lool

disable it, it causes stutters

[elder smelt]

it may look like a cpu bottleneck but it isn't

[versed knoll]

The process to disable it on Windows 10 isn't straightforward

[elder smelt]

dcontrol

1 button fix

works on w11 too

[onyx warren]

Now after the Windows Reinstall Elden Ring doesnt work anymore

Nvm had to run it as admin for some reason

[cedar mango]

Can you guys run an experiment for me?. I think I've spotted a weird behavior but I am unable to solve it until I can confirm this happens for someone else.
Whenever I load a game that does not have native HDR support in HDR (even if it doesn't enable AutoHDR) the GPU2 (used for LS) starts at 60% and never lowers while doing basically nothing. This restricts the power of the GPU for actually doing LSFG so I had to lower the FG Res to 25% to have a lag free experience.
If the same game is loaded in SDR mode, GPU2 is not taxed and I can use it at 100% FG Res without latency.

The experiment is simple. Open up any game that does not support HDR, such as Dying Light 2 or Once Human, but in HDR mode, watch the second GPU (the one connected to the monitor) and tell me if the load in your case goes up to 60% (it should stay below 30% if it's working fine).

[clear sundial]

Guys @rain hull and @elder smelt and anyone else on the AM4 platform, I need you to do a quick test to confirm a theory of mine, if you can. I might've found out the dual GPU "fix".

Just go here https://www.aida64.com/downloads and download AIDA64 portable and run the memory test and share a screenshot of this window

[elder smelt]

👀

isnt that the trial versioon?

like half the info

its funny tho I literally ran the benchmark a few hours ago

[clear sundial]

yes, but it's fine

[elder smelt]

I think I have it somewhere

[clear sundial]

The values I need are shown on the trial version too

[elder smelt]

it was in safe mode though if that makes a difference

[clear sundial]

yes it might affect latency (positively), but that's not the value I'm after

[elder smelt]

whats your theory?

you think its ram related?

[clear sundial]

I think it's L1, L2 and L3 cache related

[elder smelt]

well you may be on the right track considering my issue looks like a cpu bottleneck (it isn't)

[clear sundial]

But I need people to test that for me, even people with AM5 or other platforms. I'm looking specially for people that don't have issues with dual GPUs to test

[elder smelt]

@versed knoll are you on am4?

[clear sundial]

7800X3D

[elder smelt]

yes they are

[clear sundial]

9950x same memory config and timings

[elder smelt]

so much faster cache

[clear sundial]

I made a big mistake in not testing dual GPUs when I got that CPU, because I was 100% sure it couldn't be CPU bottleneck, so I wrote off the 4060 ti completely. But yesterday I installed the GPU back in and noticed that RTX super resolution doesn't lag anymore

[elder smelt]

wait you think its a cpu bottleneck?

[clear sundial]

I reinstalled this GPU over 5 times with my 7800X3D, always using a flashlight to confirm it was 100% plugged in, since I'm very paranoid about bad mounts. There's no way I installed it badly 5 times in a row

[elder smelt]

wait

is it an x3d issue?

the cache speed difference

its a drastic change

multiple times faster

[clear sundial]

I think it's L1, L2 and L3 cache related. So, indirectly, it might be a CPU bottleneck yes, since higher cores = higher cache speeds

[elder smelt]

hmmm

[clear sundial]

But, like I said, I don't think I'm correct. It's a very stupid theory

But I've tried everything, this was driving me mad

[elder smelt]

whats the cache speed on a non x3d cpu?

[versed knoll]

Oh, yes

[elder smelt]

cache is a huge difference either cores related

or something else

[clear sundial]

5800X (from the web) https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd.it%2F2ols89nqonz51.png%3Fauto%3Dwebp%26s%3D8ebce0d81e92a6496ec6a2226abd370e89af5e93

[elder smelt]

ehh

nah its not

[elder smelt]

can you do his test?

[versed knoll]

Extreme?

[clear sundial]

yeah, it can be trial version please

and I want to ask you if you have issues with dual GPU or not (dropping frames)

[elder smelt]

I highly doubt that I'm suffering through a pcie bottleneck too so it could 100% be cpu related

[clear sundial]

Even though Ravenger is running a 3900x, looking through the web, the aida64 numbers are higher than even 7800X3D. That's why I want to confirm this theory

[elder smelt]

I see

so aside from me and you who else had issues like this?

flexi?

I think he got it fixed though

[clear sundial]

3900x (from the web) https://www.reddit.com/media?url=https%3A%2F%2Fi.redd.it%2Fl89dv57sjeu41.jpg

[elder smelt]

yea quite higher

[versed knoll]

@clear sundial

[elder smelt]

crazy latency 👀

[versed knoll]

I knew someone would point out my cas latency 🥲

That's because of my ram, don't look at it

[clear sundial]

the reason I thought about this theory is that the drops happened when the GPU wasn't at full load. I was positive it was a memory controller bottleneck, but that didn't explain other people using an RX 6600 with success, so that's not it

[elder smelt]

so dranas the cpu you had this issue with was an x3d cpu?

[clear sundial]

Thank you, did you find issues with dual GPU?

[clear sundial]

yes

[versed knoll]

Nope, only wonky rtx 3060 results but the rx 6600m was very smooth

[elder smelt]

now i'm curious, is this an x3d issue???

who has an x3d but is also running dual gpus here

we need them

[versed knoll]

https://youtu.be/FZlwfWZ-0JM?t=140
https://youtu.be/5z1mmyORVGA?t=35
https://youtu.be/3LPsDKEv3V8?t=8

Life is good in my PC when the nvidia GPU is doing the rendering

[clear sundial]

The only other person I remember having no issues with dual GPU was running a 9800X3D

But looking through the web, even the 9800X3D has crazy values on aida64

[elder smelt]

yea its the latest and greatest cpu

[clear sundial]

9800X3D (web) https://tpucdn.com/review/amd-ryzen-7-9800x3d/images/aida64-cache-mem.png

[elder smelt]

so 7800x3d and 5700x3d had issues

but 9800x3d was fine

it can't be a coincidence that both cpus are x3ds imo

it might relate to something

[clear sundial]

your poor CPU was getting hammered on the wilds benchmark jesus

[elder smelt]

bro

bugworm also had a 5700x3d

and he had the same issue I think

[versed knoll]

playable by the way

But barely

So people with AM4 x3d CPU's are dropping frames?

[elder smelt]

not am4 specifically

dranas had am5

but all are x3d

[clear sundial]

looking through your vids you are affected though, but you also have no fps cap

I'm just extremely sensitive to jitter

[elder smelt]

playable but unbearable

we need more x3d folks here

[clear sundial]

lossless when you have a slight change in fps will result in jitter, even with gsync/freesync on

[versed knoll]

For the longest time I had the crappiest PC mankind knew, so maybe I'm not too sensitive to it

[clear sundial]

I've been there too 😅 I remember playing games at 30 fps at 480p and enjoying them. Nowadays even a slight microstutter / judder annoys me to the point of me reducing settings

[elder smelt]

same

I remember when I played with an intel igpu

0 pixels dying light

[versed knoll]

hd 6450 + phenom ii x6 1090t vs the world in 2018

[clear sundial]

I don't mind playing on lower fps as long as it's 100% stable. Having big oscilations feels horrible for me

[versed knoll]

12 fps and 200 ping in ultra low quality settings in 768p in war thunder

2019

2025

[clear sundial]

I remember in 2017 while waiting for my am5 system to arrive, I had to put my 980 ti on this PC 😅 https://www.userbenchmark.com/UserRun/4396612

[elder smelt]

beautiful

[elder smelt]

am5 in 2017 huh

early access

[versed knoll]

a time traveler

[clear sundial]

ah oops 😛

[elder smelt]

tree trunk

[clear sundial]

*am4, too lazy to change

[versed knoll]

Also in my old PC I was dumb af about taking care of it so the CPU was constantly thermal throttling

Somehow it survived the massive abuse

[clear sundial]

that PC couldn't run diablo 3 on above 17 fps btw

even with the 980 ti

[elder smelt]

the cherry on top

[versed knoll]

Yeah I wasn't joking when I said it was the worst mankind could know

[clear sundial]

My first PC back in 2008 (hp compaq presario) literally burned to death. I had black paint in my hands from using the keyboard 😅 100ºC on the CPU while on energy mode in Windows

[versed knoll]

At least I had 32gb of ram for:

[elder smelt]

insanity

[clear sundial]

I even tried running skyrim on it. 480p, potato mod settings, 30 fps on the NVIDIA Geforce 9200 GE 256mb vram

[clear sundial]

btw that ssd there? I've been using that as an OS drive in this PC until 2 weeks ago. Still works with 55 TB written to it

[elder smelt]

zamnnnn

I wish my ssd will live that long

[clear sundial]

Yeah, I hope my other ones do too! I've never had an HDD last that long lol

[elder smelt]

@lavish juniper you still have a 5700x3d?

[humble frigate]

Ah fuck, I'm on a x3d.... I won't be able to test until tomorrow though since I'm waiting for a PCIe psu cable.

[elder smelt]

its not like your gonna have issues

its just that all of the people who do have issues have an x3d

so yea

what cpu do you have?

[humble frigate]

7800x3d

[elder smelt]

uh oh

same cpu dranas had issues with

its the moment of truth

if you set everything up and you have issues then we will know

[humble frigate]

You were saying?😅😭

[elder smelt]

you're fine definitely fr

just believe

it does get me thinking though

you had issues with the 6400 yea?

but it didn't lower your base fps did it?

[humble frigate]

Yeah

It did but also put my 3080ti on 50% usage

[elder smelt]

bro

thats the same issue

that im dealing with

💀

oh no

I hope it works for you

or else we found our culprit

[humble frigate]

Wonder if it's possible to fix in future releases

[elder smelt]

fix in what way?

ls?

[humble frigate]

Yeah

[elder smelt]

I doubt it

its more hardware related

or software in windows

but it could just be a false alarm

might work fine for you

just make sure to let us stay tuned

we have to see where this ends

so cpttombstone is the 9800x3d guy who has a working setup

hmm

well we'll see soon enough

[humble frigate]

Don't know much about motherboards. Could there be a feature difference?
Or Ram? CL or amount

[elder smelt]

sure there can be but its crazy that 3 x3d users experience a similar issue

and on 2 different platforms

and lets not forgot that dranas fixed his issue by upgrading from a 7800x3d to a 9950x

I can't think that somehow all of it is a coincidence but then again who knows

also this issue looks like a cpu bottleneck but it shouldn't be happening

there needs to be more testing to be made certain

tbf rx 550 is very bad

but

it sounds like a similar issue

[humble frigate]

ugh, hope i can return this GPU if true

[elder smelt]

I hope it works fine for you I really do

It sucks for me if thats the case too

I got a spare ryzen 5 5600x but that means downgrading

[humble frigate]

so what cards are you matching @elder smelt

[elder smelt]

7900xt + 6600xt

and the same issue I've had it occur on my 1070 too but I thought it was too weak for my 7900xt so I ignored it

[humble frigate]

i see

ill let you know tomorrow for sure

[elder smelt]

🙏

[left cape]

🤮🤮 intel 🤮 🤮

if you even care

[elder smelt]

at least it ain't having issues 👀

[left cape]

when it works it works

whats the running theory on why am4 has issues?

sorry playing catch-up

l1, l2, l3 cache?

[elder smelt]

Might be x3d related not sure

Because dranas also had issues and he was using a 7800x3d

Upgraded to 9950x and boom

Fixed

Same memory config, same mobo but different cpu only

[left cape]

right

affecting render performance right?

when dual gpu

not lsfg

[elder smelt]

It gets worse with lsfg but yea

Could be different issues same cpu type but not sure

Theres only like 5? Dual gpu users with x3d cpus

[snow sparrow]

I'm having a weird issue with my 6950xt and 1080ti setup, in monster hunter wilds, for some reason even though everything is set up correctly, my frame rate is very low and my gpu isn't even utilized fully, I didn't seem to have that happen in ff7 rebirth and baldur's gate 3 (only things i managed to test)

Tried benchmarks like firestrike to test it out too and see if there's any limitations or something wrong compared to before adding the 1080ti in, but everything was fine.

[onyx warren]

Was my next buy anyways

https://tenor.com/view/shannon-sharpe-suit-meme-man-wearing-suit-meme-suit-slideshow-sparkles-and-champagne-gif-26378137

[mental peak]

@clear sundial tried it on my 5950X

[clear sundial]

Thanks for the screenshots guys, do you also have issues with dual GPU? Or does it run flawlessly? @left cape @mental peak

[clear sundial]

Even though most speeds are below am5, the L1 cache is a lot faster

And Pyro's setup demolishes the 3d chips

[mental peak]

Not flawless no, I get stutters and frame drops even when both GPUs are below 70%, I did disable hags, reset the NVCP settings and resizable bar in BIOS was already turned off beforehand

[mental peak]

How so? What numbers should I be looking at

[clear sundial]

Cache speed.

7800X3D

[clear sundial]

Win 11? Also what motherboard are you using?

[mental peak]

Win 11 pro N
https://www.asus.com/motherboards-components/motherboards/proart/proart-x570-creator-wifi/

[mental peak]

I thought the x3d chips had better performance and cache than the non x3d, why's that?

[left cape]

I cant say flawlessly, but it works more often than not.

in some cases I get 10-20 less base fps than with a single GPU set up. Other times it works absolutely flawlessly. cpu could be the culprit, but my game sample size is pretty small and I have had a lot of game specific issues

[elder smelt]

Ok im awake now

[left cape]

i have to test more, life's been busy

[elder smelt]

Today is the day

The 7800x3d will be tested today 🙏

[left cape]

godspeed

[elder smelt]

I made a post on the ls reddit and I got some really good insights ngl

7950x3d was fine for someone

But then someone else on an intel system had the same issue

Its so random

[versed knoll]

Maybe it's not that?

[elder smelt]

yea its just speculation so far

[humble frigate]

https://tenor.com/view/fingers-crossed-gif-10027140023077878069

[elder smelt]

wtf is this timespy result

https://www.3dmark.com/3dm/126165257 display connected to 7900xt

https://www.3dmark.com/3dm/126166144 connected to 6600xt

so it only happens in games?

so weird

[humble frigate]

huh. how many games/what games have you tested

[elder smelt]

I've tested 3

but 2 main ones

and both are different

one is cpu heavy other gpu heavy

maybe theres some kind of load that triggers it

wait I just tried something in 7 days to die rn

instead of normal fullscreen I did exclusive fullscreen and my fps skyrocketed

tf

normal fullscreen aka borderless

exclusive fullscreen

I have to try this on my 7900xt as display brb

If timespy was running exclusive fullscreen that explains the result

but it seems general performance improved a lot too with display connected to 7900xt

from like 95fps to 115fps while out of the pause menu

[clear sundial]

timespy is completely GPU bound. I've noticed similar results on my PC. Slightly higher performance connected to the LSFG GPU vs solo. I'm guessing since it's not displaying an image, it slightly increases performance? I dunno

[clear sundial]

They have less cores. With bigger core CPUs you have more L1 and L2 cache spread to all cores, so they can do more work overall

[elder smelt]

could be that my undervolt was on but it makes no difference imo

its quite the similar result

[clear sundial]

If they made, say, a 10950x with all cores having 3D cache, I wouldn't be surprised that those numbers would be even higher

[elder smelt]

could explain why a 7950x3d is fine too

[clear sundial]

I would try disabling SVM if you don't use virtual machines, see if it helps

with all the bullsht that windows 11 has running with virtualization in the background, I wouldn't be surprised if it gave you a performance hit. (I have that disabled by default)

[elder smelt]

@clear sundial thoughts on this?

its not perfect but more performance comes back

[clear sundial]

you're running less GPU usage, so something is interfering with your rendering GPU in borderless

[mental peak]

Interesting, although I still have huge fps drops in generated frames that I didn't happen before with only one GPU.
I do 46x3 in helldivers (with gsync), it'll randomly go to 110 fps fg, and both GPUs are at 50%. No matter the resolution scale, I tried it at 25, x2 instead, 1080p and it still drops out of nowhere

[clear sundial]

What's very strange Pyro, is that you're running on a pretty beefy motherboard with very good PCI-E lanes throughput

[mental peak]

Exactly

[clear sundial]

Basically the same system as I, but on a different platform

I would try disabling SVM in the bios and see if it does anything. Hags disabled is a must too

[elder smelt]

in your case a 9950x fixed your problem

what cpu is pyro running?

[mental peak]

5950x

[clear sundial]

5950x

[elder smelt]

so it has more cache access too

wth

[clear sundial]

but you're also running some very high latency ram though

Can you check all core usage with afterburner? (individual cores)

[elder smelt]

does latency make a difference? mine was 59ns but here I am

[clear sundial]

It helps a ton in CPU bound situation, but it isn't a magic bullet

On 3D cache CPUs it isn't that big of a deal

[mental peak]

Just checked. SVM was already disabled, so is hags, resize bar and I reset nvcp settings as well yesterday

[clear sundial]

So that rules out virtualization shenenigans... 🤔

So it might not even be a cache difference, then what the heck is it

[elder smelt]

rip

back to square one

[clear sundial]

It just doesn't make sense, how can a CPU change affect the GPU performance when it's not the bottleneck

[elder smelt]

you are the only person who managed to solve it thus far

and it was a cpu change

its bizarre

[clear sundial]

I'm using the same windows version, same drivers, same everything. Just plopped it in, enabled EXPO and the settings I had on my previous CPU

[elder smelt]

it makes absolutely no sense here

and pyro has the same issue somehow with a 5950x

[clear sundial]

we need more data

[elder smelt]

mulle is gonna test his 7800x3d soon

would be a great help

[mental peak]

It also doesn't matter if the GPUs are undervolted or not, I tested both with and without and it still happens

[elder smelt]

same here

its regardless of the gpu

[clear sundial]

very stupid question, but do you guys run lossless in the same drive as the game's themselves?

[elder smelt]

no but it doesn't make a difference if my games are running crap without it 😄

[mental peak]

No. I run lossless on my main ssd, most of my games are on my second ssd

[elder smelt]

"6800xt is connected to pcie 5.0 and 3050 is right below it at pcie 3.0 x4 cpu is a 12600k and MB is a z690 msi pro" same issue as us

[mental peak]

So, so far it happens regardless of the GPU, cpu, motherboard, game and ssd

[elder smelt]

somehow dranas fixed it with a 9950x

[clear sundial]

3.0 x4 is very weak for a second card

[elder smelt]

I agree

but if he experienced a pcie bottleneck then are we as well?

[clear sundial]

even a RX 6400 throttles to oblivion just watching videos at that speed. I had one in the past

I think our situation is different

Just a coincidence

[elder smelt]

probably

[clear sundial]

You're running dual AMD cards now?

[elder smelt]

yes

7900xt + 6600xt

[clear sundial]

I was going to suggest running display driver only, but since you're running both AMD cards, I don't think it would be worth it

[elder smelt]

🤷‍♂️

I can try it later

[clear sundial]

If AMD (Rendering) + NVIDIA (LSFG), I suggest display driver only for AMD, full install on the nvidia card

[elder smelt]

the thing is this also happened with my 1070 too

[clear sundial]

Also, this was the driver I was running before selling my 7900 xtx https://www.amd.com/en/resources/support-articles/release-notes/RN-PRO-WIN-24-Q4.html

[elder smelt]

used to run it too

[clear sundial]

display only + full nvidia driver (without the app or geforce experience)

[clear sundial]

What I find specially weird, is that on fullscreen it works amazingly. Which shows it's something messing with the driver in borderless, since in exclusive fullscreen, windows leaves all the rendering to the GPU driver instead of using DWM

[elder smelt]

not for me tbh

ingame my game runs at like 95 fps with 6600xt as display regardless of borderless or fullscreen

[clear sundial]

didn't you say your FPS skyrocketed in exclusive?

[elder smelt]

but its 115fps with 7900xt

[elder smelt]

it did but that was in the pause screen

it sorta helped

its so odd

when its unpaused its pretty much the same as borderless

it seems like something is bottlenecking my cpu or something

[clear sundial]

My issue wasn't dropping base fps from the main gpu though, just unstable LSFG performance on the LSFG card with headroom.

But I'm still trying to think about your issue though

[elder smelt]

I'm not sure at all

rip

I'm gonna save up for an am5 system at some point but I'm not sure if that will fix it

[clear sundial]

I don't recommend it

I would've stayed AM4 if my 7 year old Motherboard didn't go poof

[elder smelt]

yea this platform is a beast

this is my only problem with it

[clear sundial]

I loved that socket so much. Insanely fast boot times, solid performance, cheap. AM5 is finnicky, specially with RAM. You can reduce boot times, but it's still pretty slow compared to am4

14.1s Bios boot time, on my am4 system it boot in 6-7s. IF you disable memory context restore, it boots in almost a minute with EXPO enabled...

[elder smelt]

💀

[clear sundial]

The thing with memory context restore is that it skips memory training and if your ram isn't stable, you're going to have a pretty bad time, since it can cause a lot of issues. If it's stable, it's a must have... taking a minute to reboot a system is a big yikes

[elder smelt]

I heard alot about memory training in am5

big deal

[clear sundial]

It's the Achilies heel of AM5 😓

[elder smelt]

ddr5 ram is insane too from what I've heard

huge performance difference depending on it

even more ram dependent than am4

[clear sundial]

Well, am4 in the beginning was like that too. DDR5 when it released was horrible, uber high latency, very expensive. Nowadays it's pretty good.

[elder smelt]

am5 has its 3rd gen now right? I'd expect it to get better soonish then

[clear sundial]

second

[elder smelt]

very early then

[elder smelt]

my issue is so stupid

timespy perfectly fine scores, hell its even better

then in games and when using lsfg it all breaks down

it makes 0 sense

[meager yoke]

I'm getting freezes and have to restart my PC anyone experiencing that?

My config is well... not great, intel 11800h and a dGPU RX 480

Trying to use the iGPU with the dGPU

It worked once and and now I don't know why it's not working

[versed knoll]

Maybe something with your PSU? maybe something's overheating?

Monitoring the stats while using it is the best way to find out

[clear sundial]

Freezes could be unstable RAM. I've started having the same, randomly, and saw that the tight timings I was running on my previous CPU aren't fully stable on this one. Dialed back the timings and it now runs stable.

Specially since you mentioned using the iGPU, which relies on system RAM to operate

[humble frigate]

The cable finally came. Have to head out to do some errands. Did an extremely fast test and it's the same result as the rx6400. Cyberpunk went from 84 fps to 50 and then doubled.

[elder smelt]

oh no

[humble frigate]

To clarify now it's a 3080ti with an rx6600. Also have a 7800x3d

[elder smelt]

does it look like a cpu bottleneck?

[humble frigate]

I didn't have time to check in depth. Will test more in depth in a couple of hours.

[elder smelt]

you know at this point I think I may have a motherboard issue here

dual gpu with 7900xt was still somewhat off I think

stutters were worse

I'm out of ideas too

not really sure what part of my system is the issue

[clear sundial]

Just to make sure, you followed all the recommendations i wrote here, right? #1328337747399938138 message

[elder smelt]

I did most of those but still the same

the biggest help was chipset driver

[humble frigate]

How come? Since others are having the same issue

[elder smelt]

its not exactly the same issue

but I don't know why there's such a discrepancy in performance for my system compared to others

[humble frigate]

so i have tested games on same and sepperate SSD. both times the rx goes to 97% and my 3080 goes to 50%-60%

[elder smelt]

do you lose performance even without lsfg?

[humble frigate]

gimme min. didnt feel like it but i will check

[elder smelt]

it isn't clear on some games but very clear on others

but when I use lsfg it doesn't matter

fps gets heavily reduced

[humble frigate]

cuberpunk looks fine before LSFG. but it says my RX660 is maxed even before LSFG is on

that seems odd?

[elder smelt]

that happened to my 1070 but not my 6600xt

it might be pushing the max frames it can send to the other gpu?

might be pcie

whats your setup again?

[humble frigate]

3080TI to RX6600

7800x3d

[elder smelt]

what about pcie?

what does gpuz say

[humble frigate]

on a tuf gaming B650MB-plus

[elder smelt]

so main gpu is pcie 4 x16 and 2nd is pcie 4 x4

can you confirm with gpuz?

[humble frigate]

dont know where i see that?

my rx is 100%usage with LSFG off, that makes no sense to me

[elder smelt]

thats cpuz

use gpuz

[elder smelt]

could be maxing out pcie or something

[humble frigate]

my bad

seems like it

[elder smelt]

your 3080ti is doing x16 at pcie 1.1

usually power saving feature

so its fine there

pcie 4 at x4 is the same as me running gen 3 x8

not sure if that is the bottleneck or not

shouldn't be tbh

[humble frigate]

so i have NVME on my MB thoose wouldnt occopie some of the same lanes in the pcie right? it would show?

[elder smelt]

it would show

but it doesn't do anything for your case

@clear sundial @rain hull thoughts?

[humble frigate]

just so im on the same page. you are speculating in pcie bottleneck?

[onyx warren]

Welcome to dual GPU

[humble frigate]

its normal?

because right now desktop window manager is eating my GPU for some reason

[onyx warren]

Problems that make no sense are normal

[elder smelt]

yep

then we have people like ravenger who have no issues
