Description
Can not run many games on steam through proton using pvkrun on my dual GPU system. Or they just don't launch or it gives an assertion:
I have two graphics cards, GTX 1080 with the monitor attached to it and one RTX 3090. My system is Arch running KDE desktop. The command I use to use the GTX 1080 as display and the RTX 3090 as rendering is: PRIMUS_VK_DISPLAYID=10de:1b80 PRIMUS_VK_RENDERID=10de:2204 pvkrun %command%
Running the steam games without pvkrun (display and render on the GTX 1080) works fine. Also running other non steam apps with this command (ex. vkcubes) also work fine (doing the rendering on the RTX 3090 and displaying through GTX 1080).
I tried on X11 and Wayland. On Wayland not even vkcubes is working. Also tried with different version of proton (Experimental, GE, 9.0...)
Any recommendation on how to solve this issue?
