I have Arch linux with kde plasma. Now the problem is, i play Ark survival ascended, and its wery demanding game. But for some reason only 80% of my gpu is used. In cs go 2 its also using 80% of my gpu in game but thats fine because it gives me 300+ fps so i dont complain about not using my gpu to the max. But in menus and settings of cs go it ramps up to 99% usage, while in ark it stays to 80% even in menus before game starts.

I would guess, the game Ark is not just rendering a scene but all the other parts like CPU is also used. And the game logic itself tries to balance its usage or GPU is limited by the CPU or RAM speed in example. While the menus you was talking might not have any fps limits, and doesn’t use anything other than the GPU (for the most part) and renders as much as it possible can. Edit: OK I didn’t read properly… So the 80% of Ark is in the menu too? Well maybe the game has builtin limits in the menu, and CS:GO does not.
BTW for that reason I recommend fps limits or any sort of VSync. Some games allow limiting the framerate in menus separately from the ingame. If I’m not mistaken Marvel Rivals is such a game that allows that.
CS2 has an option to limit fps in menus separately as well. Really important to put on
Just noticed I still say CS:GO. :D Edit: To add something more of a value to this (mine) reply, limiting framerate in menus will not stress your GPU for no reason, and also don’t waste power if that is important too; for money or for mobile hardware in example.
