-
-screen-heightCopyOverride the screen height (Unity games)- Effect
- Must be an integer from a resolution the game supports. Pair with -screen-width.
- Example
-screen-width 1920 -screen-height 1080
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 -
-popupwindowCopyRun in a borderless window (Unity games)- Effect
- Creates the window as a dialog with no frame. Not supported on macOS.
DisplaySafe -
-screen-widthCopyOverride the screen width (Unity games)- Effect
- Must be an integer from a resolution the game supports. Pair with -screen-height; alone it can leave a mismatched aspect ratio.
- Example
-screen-width 1920 -screen-height 1080
DisplaySafe -
-window-modeCopyOverride fullscreen windowed mode (Unity games, Windows)- Effect
- Takes exclusive or borderless. Windows only. The flag alone does nothing — the value is required.
- Example
-window-mode borderless
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.

- 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.

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.
