-
-popupwindowCopyRun in a borderless window (Unity games)- Effect
- Creates the window as a dialog with no frame. Not supported on macOS.
DisplaySafe -
-force-openglCopyForce the legacy OpenGL renderer (Unity games, legacy builds)- Effect
- Windows only. Selects Unity's LEGACY OpenGL backend, not the core profile — use -force-glcore for that. Builds made with newer Unity versions may not carry the legacy backend at all, in which case this has no effect.
DisplaySafe -
-force-d3d11CopyForce the Direct3D 11 renderer (Unity games)- Effect
- Windows only.
DisplaySafe -
-force-d3d12CopyForce the Direct3D 12 renderer (Unity games)- Effect
- Windows only.
DisplaySafe -
-force-vulkanCopyForce the Vulkan renderer (Unity games)- Effect
- Useful where the default backend crashes or performs badly; ignored if the build has no Vulkan path.
DisplaySafe -
-force-low-power-deviceCopyUse the low-power GPU (Unity games, macOS)- Effect
- macOS only. Picks the integrated GPU over the discrete one, trading performance for battery life.

- Turns off in-process esync primitives. Worth trying for games that hang or crash under Proton.
Proton-DeckSafe -
-windowedCopyRun in windowed mode (Unreal Engine and Source games)- Effect

- Example
-windowed -ResX=1920 -ResY=1080
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 -
-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.

-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.

-windowed -ResX=1920 -ResY=1080
DisplaySafe -
-dx11CopyUse the DirectX 11 renderer (Unreal Engine games)- Effect
- Selects DX11 as the RHI. Ignored by builds without a DX11 path.

-ResY=1080CopySet the window height in pixels (Unreal Engine games)- Effect

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.
