PROTON_USE_D9VK=1 %command%CopyUse DXVK for Direct3D 9 (obsolete) (Linux, Proton 4.x and earlier)- Effect
- Valve marks it obsoleted as of Proton 5.0 — DXVK became the default for d3d9, so on any current Proton this does nothing. In older versions it selected Vulkan-based DXVK over OpenGL-based wined3d.

PROTON_USE_WINED3D=1 %command%CopyUse wined3d (OpenGL) instead of DXVK (Linux, Proton)- Effect
- Routes d3d11, d3d10 and d3d9 through OpenGL-based wined3d rather than Vulkan-based DXVK. Usually slower; a fallback where DXVK fails.

gamemoderun %command%CopyRun the game under Feral GameMode (Linux)- Effect
- Applies temporary host optimisations (CPU governor, I/O and process priority) for the game's lifetime, then restores them on exit. GameMode runs the game, so %command% is what it runs.

How to apply a launch option on Steam
- Open Steam and go to your Library.
- Right-click the game and choose Properties.
- On the General tab, find the Launch Options field.
- Type or paste the option (e.g.
-windowed) into the field. To use several at once, separate them with spaces (e.g.-windowed -novid). - Close Properties. Steam saves automatically, and the option applies next time you launch the game.
To remove one, reopen the same field and delete the text. Options are game-specific; an option that helps one game may do nothing (or misbehave) in another.
Worth knowing: a launch option can break a game's rendering, reset local settings, or trip anti-cheat in multiplayer. Read the description first, add one at a time, and treat anything rated above Safe as a deliberate experiment.
