<pre>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.</pre>
