--- Comment #11 from Joe Alec <[email protected]> --- I've been playing around with this env var `KWIN_DRM_DEVICES`, and I want to share some observations - If Nvidia GPU is first, then Intel `KWIN_DRM_DEVICES="/dev/dri/by-path/pci-0000\:01\:00.0-card:/dev/dri/by-path/pci-0000\:00\:02.0-card"` Then as I mentioned earlier no game can use the internal GPU - If Intel is first, then NVIDIA, then the original bug could be observed (massive FPS in OpenGL and jittery Vulkan games) This is equivalent to not setting this env var Does that mean the compositor sticks to one GPU (the first it decides to use) for rendering and refuses to use the other GPU later? Would it help to downgrade and try everything on the older kwin 6.6.4 and upload all the logs? -- You are receiving this mail because: You are watching all bug changes.
