OpenGL renderer string: AMD VEGAM (DRM 3.27.0, 4.20.3-arch1-1-ARCH, LLVM 7.0.0) Dell XPS 9575 AMD's discrete GPU on the Kaby Lake architecture performs significantly worse under Linux than under Windows. Below are some rudimentary data I've collected: Game Linux Windows TF2 30-50 FPS 60-100 FPS Borderlands 2 30-43 FPS 42-52 FPS Minecraft 60+ FPS 40-50 FPS CSGO 40-55 FPS 60+ FPS Notably, Minecraft is the exception, performing much better under Linux for some reason. All of the Source engine games (CSGO, TF2) I tested also had a very severe stutter, which would happen every other second.
