#LSFG cant upscale above monitor's refresh rate using DXGI api

I dont know why but whenever I use the DXGI api in the newest version, it just never scales above 75fps which is my max monitor's refresh rate. I even checked, vsync is disabled. If I use the WGC api then everything is okay but this only seems to be happening with the DXGI api.

The only solution which seemed to fix this issue is to roll back to the 2.82 legacy version which seemed to fix everything. Are there any alternatives to this issue or is it supposed to be like that? Are there any benefits to interpolate above the max monitor's refresh rate?

why do you want more fps since you have 75hz monitor? It doesn't generate more fps on purpose for performance reasons. It generates only the needed fps.

#🔗│updates
It's intended

ionic lintel
#

the more your base fps is the less your input latency will be. So yeah going from 60->75 instead of 37.5->75 probably is better

#

skipping fps can cause pasing issues though

limpid vortex
#

am I better off just not using lsfg in this scenario or will lsfg benefit me in this case? Cuz my max refresh rate is just 75 and I get 60-75 fps in game

ionic lintel
#

ehm I don't know if it's worth it if you are already getting 60-75 fps 😅

ohh okay, also one more thing. I have a live wallpaper software called wallpaper engine and I was wondering how to get lsfg work on that.

lean ibex
#

I have Wallpaper Engine too but why would want it to work on that?

limpid vortex
#

make 30 fps wallpaper to 60 or 75 fps with much lesser gpu usage?

#

cuz just changing the max framerate in settings increases the gpu usage by quiet a bit

lean ibex
#

I don't think that's the use case of LS
It only works in windowed/borderless applications and not on your desktop like that

lean ibex

#

Keep in mind that LS is a tool that you should activate when you need it and not having it active constantly

limpid vortex
#

so its basically useful when I have a very low framerate like 30 or 40 fps?

lean ibex
#

It has different use cases
For FPS capped games/emulated games for example
Or videos
Or when you are CPU limited in a game
And yes if you have a low framerate and are not GPU limited hard you can use it too

#

Higher refresh rate = you will benefit more from it

Youtube, Anime

limpid vortex
#

how can this benefit me in youtube?

lean ibex
#

On a 75 Hz screen not really I guess
But on a 120 Hz screen for example you could watch 60 FPS videos in 120 FPS

When I click fullscreen on a YT video then it works on that

No problem!

hi sorry to disturb again but whenever I tried using lsfg on stuff like a browser, my curser and the screen just seems to be stuttering for some reason. Its completely fine wen something like a video is scrolling but when nothing is playing, my curser and the framerate just lags and stutters a lot. The framerate also comes down to the single digits. Is this normal? How can I fix this for a smoother experience?

lean ibex
#

Definitely not normal

#

Oh I see what you might mean

#

When a video ends in fullscreen and you wanna scroll to the next one the mouse cursor lags really hard

limpid vortex
#

yep

lean ibex
#

Same here

limpid vortex
#

exactly that

#

but when the video is playing its just fine

lean ibex
#

But I don't use LS like that anyway
I just disable it again and tab out of fullscreen and then click on the next video

limpid vortex
#

ahh okay, just wanted to confirm or if I was just going crazy

lean ibex
#

I think I might know the reason

limpid vortex
#

is there any fix to this tho?

lean ibex
#

LS reads the FPS and doubles/triples it
But when there's no video playing anymore it cannot pick up the FPS and therefore it lags

limpid vortex
lean ibex
#

You can just press the LS hotkey once the video ends, click on the new one and then press the hotkey again

#

Not the worst thing in the world

limpid vortex
#

alright

#

thanks again for the help

lean ibex
#

No issue

That probably means your modded skyrim is already straining your GPU hard
Frame Gen puts extra load on your GPU

#

Yeah running LS as admin is recommended

#

I'd first like to know how high your GPU usage is when playing Skyrim

#

Okay so it's not your GPU usage

#

Maybe your VRAM is filling with LS active

#

Your VRAM usage is at 7.2 GB on its own already out of 8

#

What does your VRAM usage say when you activate LS?

#

Huh so it's not using any VRAM at all?

#

Are you using performance mode in LS?

#

Why not?

lean ibex
#

Performance mode means it uses less resources but therefore can have more artifacts
Means better performance in your games

#

52/49 is a very weird value
Usually the second number should be bigger than the first

#

Do you have multiple screens?

#

Two?

#

Hm okay...
Then this could be a bit more tricky

#

Wait are you playing on only one screen or multiple simultaneously?

#

Okay

#

Could you try to play the game on one of the other two monitors and set LS to output to your middle monitor?

#

Output display

#

Just a heads up: If it works correctly it will show the game with its normal FPS on the monitor you play it on and it should show the game with generated FPS on the middle monitor that way
So you'll see it twice
But this is just a test

#

Very odd
What happens when you use WGC instead of DXGI API?

#

What would happen if you set your ingame FPS to 30?

#

Lossless is theoretically not recommended for 60 Hz screens

#

Select DXGI API and try again

#

Hm very odd

#

No that shouldn't be an issue

#

Which resolution are you playing on?

#

Could you try setting it to 1080p and then tell me the LS FPS?

#

very weird
For some reason your generated FPS is stuck on 49

#

In theory that would mean your monitor is set to 49 Hz

#

But of course that's impossible

#

Is your game set to borderless or windowed?

#

Does changing it to windowed mode change anything?

#

Hm...

#

And if you set it to x3? Still the same?

#

There's something weird going on

#

I'm gonna be honest:
I've dealt with a lot of Lossless issues but this one's the first of its kind

#

The same exact thing?

#

Always /48 ?

#

You just said it's the same thing

#

I mean like I said you're pretty limited on it in the first place because of only having a 60 Hz screen

#

The higher your refresh rate the more you should benefit from it

#

Hm okay
And the tested screens on all three PCs are all 60 Hz?

#

Like I said so far I've helped a lot of users and never read about 48 generated FPS caps

#

If it happens to three PCs in your household it more sounds like a user error than an app error

#

That's what I'm wondering too

#

Which video?

#

I don't know if he does something strange with it but

The normal use case should be:
Set Scaling mode to auto and fullscreen
Set Frame Gen to x2 (or x3)
Use performance mode if your GPU can't keep up with the Frame Gen
Cap your FPS to half of your refresh rate with x2 (or one third of your refresh rate with x3)
And then press the Lossless hotkey ingame

But yeah your problem is very strange

#

Yeah like I said
It has to be a user error of some sorts
Maybe a program that is installed on all three PCs that limits the max FPS or makes Lossless detect a lower FPS

#

Are you on Windows 10?

lean ibex
#

Hm I see. I'm on Windows 10. I don't know if that could cause an issue too
