Brightness Curve in Manage DIsplay mode: Nvidia GPU only is not right

[merry meteor]

I found the reason

The cpu is running at 3-4.5GHz at idle in
Power plan: Legion Balance Mode &
windows power mode: Balanced

For some reason

Cpu usage is about 4- 9%

With only 4 active threads and rest are parked

[sonic drift]

Check minimum cpu performance state?

[merry meteor]

Well this is another problem, i cant check cuz i cant access the power plan settings

[sonic drift]

Not even default balanced?

[merry meteor]

Balanced is accessible but im using the custom Legion power plans

[sonic drift]

Try via QuickCPU

[merry meteor]

Gimme a sec, Opening the laptop

Ok, wait, i think i can fix the power plan problem

I have done it before

[sonic drift]

You can try deleting the plans btw and redownload them from Lenovo.

Also, did you touch speedshift epp in throttlestop? It control boost aggressiveness

[merry meteor]

fixed the problem, just have to comment the del line by adding REM

[merry meteor]

fresh windows install all stock havent touched anything yet

also didnt bother with throttlestop cuz i have an H processor so cant even undervolt

i ll AC loadline but that is a project for later

[merry meteor]

it is disabled (auto set by windows)

currently 128

@sonic drift this is a bit high for idle dont u think?

sending a video*

nvm, turns out cuz of the recording the cpu usage was higher

still sending video, srry for the hassle*

but video still shows the high frequency at idle, imma check minimum

it is 5%

the default

[sonic drift]

With what are you recording though? Just tried Shadowplay. Cpu clocks didn't increase

[merry meteor]

snipping tool

[sonic drift]

Just tried. Encoding was on dGPU, so no increase in clock speeds

[merry meteor]

yeah trying rn

[sonic drift]

No e core usage. Interesting

[merry meteor]

yeah been noticing that too, even before fresh windows install cpu was fully relying on P cores

[sonic drift]

You are on the latest bios and ME firmware, right?

[merry meteor]

specially in low usage senarios

[merry meteor]

latest bios ✅
wut is ME

intel Management Engine?

[sonic drift]

ye

It is required for APO so it must be doing something with core management

[merry meteor]

havent checked, i let winfows updates & Legion Toolkit handle things

checking

imma jsut straight up update

install first 3?

[sonic drift]

Do try

[merry meteor]

donwloaded those

[merry meteor]

3rd and 4th the same i see

https://tenor.com/view/sweats-gif-25346666

[sonic drift]

iirc yeah, they require reboot

[merry meteor]

how do u record, just tried alt + f9 i get this

using the New Nvidia App

[sonic drift]

Alt+z

Enable desktop capture in settings

[merry meteor]

u need to Be in DGPU mode or Laptop Display Mode: Nvidia GPU only

noice

[sonic drift]

Oh

[merry meteor]

tried to use OBS , tried to optimize, damn higher usage than both

Nvenc AV1 + Weighted Sum scaling

anyways

no difference in cpu usage at idle, still spiking to 4.5GHz at <10% usage

im not hearing fan spikes tho

why am i discovering issues after issues

[sonic drift]

You are using Lenovos dgpu and igpu drivers right?

[merry meteor]

yep

[merry meteor]

visual representation of how i feel the brightness curve is like

in Manage Display mode :Nvidia GPU only

[sonic drift]

What about dGPU only mode?

[merry meteor]

imma try wait a sec

back

issue is not there in dGPU mode

but

it feels more like an exponential curve (which is not a big deal)

[sonic drift]

Let's try yoloing it

Disable MPO

You are on 24h2 right?

[merry meteor]

yep

made this curve

this is how it feels in dGPU mode

in optimus mode, it is linear

[merry meteor]

done

[merry meteor]

i think i saw something like that in teh driver folder

[merry meteor]

back to Hybrid mode

nop no difference

[sonic drift]

ec reset?

[dusty finch]

Legolander The Skelim

__How to perform an ec reset__

Soft EC reset:
Shutdown the laptop, unplug all cables, charger too.
Press and hold power button for 60 seconds, keep holding even if the laptops powers on, release after 60 seconds and then power o...

Result 1 of 2

[merry meteor]

Back

[merry meteor]

Ok

Soft ec reset done

Nop, no difference

adding to the list of issues:

gpu not turning off in Hybrid - iGPU mode

[merry meteor]

u know, the ec reset did help with the idle high frequency, seems way lower now, it didnt reach 1.4GHz at idle before

why does fresh installing windows introduces issues

[sonic drift]

You can try going back to factory image

[merry meteor]

currently i hae a limited data plan, so i going to public place it download that 32GB "Recovery media" , tho it is 23H2

i have made a bad move that i downloaded 24H2 english International iso so cant use that for inplace upgrade

so for now i'd rather try to fix this version till i do that, which will probably be next week cuz im travelling

[merry meteor]

this is weird

[merry meteor]

this only happens with Legion toolkit

when enabling LmController and closing legion toolkit (basically using Vantage)

and set it to iGPU mode, the gpu gets disabled within 2 seconds

so Legion toolkit issue?

same for the other issue where the gpu doesnt get enabled when
in hybrid auto && on battery && the GPU is disabled

the GPU doesnt turn back on with Legion toolkit running in the background, only GPU turns back on when Vantage (LmController) is enabled
