use my second gpu

I have 2 gpus, and I want to use my second gpu to run csgo, I tried using PRIME following the arch wiki steps it gave the results it is supposed to give me but when I run the game it still uses the first gpu
(I run that game from steam which I run also using flatpak)

Re: use my second gpu

Don't use flatpak. Its sandbox will prevent the relevant injections necessary from happening

Re: use my second gpu

Please don't do that, https://wiki.archlinux.org/index.php/Co … ct#Bumping

Is the issue with one game or with multiple ?
If only one, which one ?

What command are you using to start the game ?
please post it and the output steam gives.

Re: use my second gpu

sorry I am new to the community
so i have only 1 game (counter strike global offensive)
what I did are the 2 commands in GPU offloading here https://wiki.archlinux.org/index.php/PR … offloading and then I ran steam but it didn't work
I read somewhere else that I should run steam using DRI_PRIME=1 steam but it still doesn't work

steam doesn't give any output...

Re: use my second gpu

it will if you start it in a terminal, and yes you need to use DRI_PRIME=1 whenever you want the other gpu to be used (the two commands you ran aren't necessary anymore just for offloading with sufficiently modern xorg and mesa which we have). You might want to apply that just to the games you intend to start with this however, see: https://wiki.archlinux.org/index.php/St … ch_options

By what measure do you determine that it "doesn't use" your discrete GPU? What do you get for

glxinfo -b
DRI_PRIME=1 glxinfo -b

post these wrapped in [ code ] [ /code ] tags without the spaces.

the problem is that I must run the game using steam so idk how to specify the game using DRI_PRIME...
I think it is not using my discrete gpu because I am playing on "low" fps

Re: use my second gpu

You can add it to game's Launch Options. Right click to the game -> select Properties -> "Set Launch Options.." button and there you put:

DRI_PRIME=1 %command%

Re: use my second gpu

What you mean? You wrote above that you run the game from steam. In steam library(where all your steam games are), right click on game' s title.

Re: use my second gpu

You should also post the DRI_PRIME=1 variant, if the used renderer differs then your dedicated GPU is used and there should be no way for any game to come to a differing conclusion.

"Low fps" can have a variety of reasons and you could get that from the dedicated GPU as well, how low are we talking? But yes it'd be best if you could post the output generated here.
