Issues unresolved[edit]

Chromatic aberration always on[edit]

Chromatic aberration stays on even after disabling it through the video options. Its associate variable mat_chromatic_damage_enable doesn't work either.

Issues fixed[edit]

Black screen while in fullscreen mode (Windows 10)[edit]

Enable borderless fullscreen windowed mode[5]
If an adaptive sync monitor is used, set it to run in windowed mode if possible. This is an option for G-Sync at least.

Very poor performance on AMDGPU kernel driver (Linux)[edit]

It is possible to run the game without starting Steam by running bms.sh
Remove the included libstdc++.so.6[6]
  1. Go to [SteamLibraryDir]/steamapps/common/Black Mesa/bin
  2. Remove libstdc++.so.6
Run the game in Steam Native environment[citation needed]
