-
-fullscreenCopyRun in fullscreen mode (Unreal Engine and Source games)- Effect
- Overrides a saved windowed preference. -full is the same option in Source.
DisplaySafe -
-dx12CopyUse the DirectX 12 renderer (Unreal Engine games)- Effect
- Selects DX12 as the RHI. Ignored by builds without a DX12 path.
DisplaySafe -
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-DeckSafe -
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.

DXVK_HUD=fullCopyShow the DXVK performance HUD overlay (e.g. DXVK_HUD=fps)Proton-DeckSafe -
-dx11CopyUse the DirectX 11 renderer (Unreal Engine games)- Effect
- Selects DX11 as the RHI. Ignored by builds without a DX11 path.
DisplaySafe -
-USEALLAVAILABLECORESCopyUse all available CPU cores (Unreal Engine games)- Effect
- Lifts a core-count limit the engine would otherwise apply. Epic documents it as "Use all available cores."
PerformanceSafe -
-tcpCopyExperimental -
PROTON_FORCE_LARGE_ADDRESS_AWARE=1 %command%CopyForce the LARGE_ADDRESS_AWARE flag (Linux, Proton)- Effect
- Lets 32-bit executables address more than 2 GB. Valve documents it as enabled by default, so setting it explicitly is usually a no-op.
Proton-DeckSafe -
PROTON_NO_ESYNC=1 %command%CopyDisable eventfd-based synchronisation (Linux, Proton)- Effect
- Turns off in-process esync primitives. Worth trying for games that hang or crash under Proton.
Proton-DeckSafe -
-ResX=1920CopySet the window width in pixels (Unreal Engine games)- Effect
- Takes its value with = and no space. Epic pairs it with -ResY and -windowed.
- Example
-windowed -ResX=1920 -ResY=1080
DisplaySafe -
-ResY=1080CopySet the window height in pixels (Unreal Engine games)- Effect
- Takes its value with = and no space. Epic pairs it with -ResX and -windowed.
- Example
-windowed -ResX=1920 -ResY=1080
DisplaySafe -
-nosplashCopySkip splash screensSkip-IntroSafe -
-nolauncherCopySkip the game's external launcher (only games that ship a launcher)- Effect
- Starts the game directly instead of opening its separate launcher or configuration window first. The exact spelling varies per title.
Experimental -
-windowedCopyRun in windowed mode (Unreal Engine and Source games)- Effect
- Unreal documents pairing it with an explicit resolution. In Source -window, -sw and -startwindowed are the same option.
- Example
-windowed -ResX=1920 -ResY=1080
DisplaySafe -
-nostartupmoviesCopySkip the startup movies (Unreal Engine games)- Effect
- Prevents intro and logo movies from playing at launch.
Skip-IntroSafe -
-nomoviesCopySkip intro movies (game-specific, not an engine-wide standard)- Effect
- Prevents pre-game cinematic and logo movies from playing. Source games use -novid instead.

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.
