Nvidia Prime and Steam Launch Options

Hello everyone,
I have been using Garuda for a few weeks now and despite some hickups at the beginning, I am loving it.

At the beginning it was a bit of a headache to get Nvidia drivers and Prime running, but now everything is running smoothly so far. I am just seeking a little explanation as to what I am doing to better understand and avoid mistakes in the future, since any Information I found on it was rather scarce…

To cut to the chase: I am currently playing 2 games, Helldivers 2 and Tekken 8. Both require launch options, to work properly. At first I thought I had to add

prime-run %command%

as launch option to every game in order to play it using my dedicated graphics card. For Tekken 8 I need to set a

HOST_LC_ALL=de_DE.UTF-8 %command%

as launch option, for it to set my player region correctly. It took a lot of research, trial and error to find out that I don’t need “prime-run” for Tekken 8.

So I am wondering why that is or if I am doing something wrong…
Is it game specific if it determines which graphics card to use itself or by OS?
Am I running my game on integrated graphics and am not realising it?

I am kinda confused as to how steam launch options work in the first place, and how to chain them together or what individual parts even do, since they don’t resemble program parameters I’m familiar with, but maybe that is just my lack of knowledge. :sweat_smile:
In my research I found out that apparently %command% is what actually launches the game and prime somehow sets up an environment before that or something…

For now everything seems works fine. Helldivers runs easy on 200FPS and Tekken finally set me to EU. I am just seeking some explanation…

Inxi below, just in case:

Btw, sorry if this is the wrong place for this. Felt more like a Linux Question, than a Steam Question to me…

I guess this is the wrong place then, okay…
