Hi all…linux noob here.

It seems my nvidia gpu is not getting the power it should and as a result fps are lower

sudo nvidia-smi -q -d POWER

sudo nvidia-smi -pl 95
Changing power management limit is not supported in current scope for GPU: 00000000:01:00.0.
All done.

So it doesn’t do anything.

I’m on KDE Plasma 6.1.4 & WM: KWin (Wayland). And yes I have set the power to performance in KDE’s setting.

Hopefully someone can shed some light on how to increase the power limit :slight_smile:

Now I don’t know if it’s weird or not…when I connect my laptop to my TV, which is a 77 inc LG C1, then somehow the power draw is around 85w to 94w << still below the max 105W on the maxQ 3080 this laptop has. And yeah performance is well below compared to what I saw in w11…still I prefer cachy to some spyware os.

You can not do anything there, thats a nvidia issue and there are several reports about this in their forum

Thanks everyone for your input. Yeah well I’m still not going back to spyware11…I do my actual work on cachyos and on my other one I just game…m$ can spy as much as they want getting game screenshots.

And frankly having a low wattage pull the overall laptop remains cooler and overall fps also seems better than watching it yoyo.

Guess I’ll just wait it out :slight_smile:
