Proton Launch Options

These are the launch commands I use for gaming on Steam through Proton

  1. DXVK_HUD=full: Shows FPS, GPU, and other information (useful when coupled with Wayland since Steam's overlay will not work under Wayland to show FPS)
  2. DXVK_FRAME_RATE: Sets target frame rate to limit (usually better than game-specific frame limiters or vsync)
  3. PROTON_USE_NTSYNC: Better Linux-to-Windows NT synchronization than fsync and esync hacks (good for CPU-intensive games)
  4. PROTON_ENABLE_WAYLAND: Forces game to use Wayland instead of X11
  5. %command%: Steam environmental value for when the executable should run in the launch option (should usually always be at the end)

DXVK_HUD=full DXVK_FRAME_RATE=95 PROTON_USE_NTSYNC=1 PROTON_ENABLE_WAYLAND=1 %command%
