--- Comment #1 from [email protected] --- After looking at the difference in the environment between the two methods of launching Steam, I have isolated this issue to the KRunner/startmenu launch method setting DRI_PRIME=pci-0000_00_02_0, which is my integrated GPU instead of my dedicated GPU. Steam seems to be smart enough to use my dedicated GPU for rendering the actual game (or else the performance would be even worse), but Gamescope seems to be using the iGPU for some of its business which causes the performance issue. Where might I find the correct lever to pull to stop KRunner from setting DRI_PRIME to my iGPU? -- You are receiving this mail because: You are watching all bug changes.
