EngineSource 2
-
-highCopyRun the game at High process priority (Source engine games)- Effect
- Raises the OS scheduling priority of the game process. It does not add CPU capacity, so it helps only where something else is competing for the processor.
PerformanceSafe -
-novidCopySkip the intro video (Source engine games)- Effect
- The startup video does not play. Saves several seconds on every launch and is the most common Source launch option.
Skip-IntroSafe -
-consoleCopyEnable the developer console- Effect
- Makes the in-game developer console available, opened with the ~ key.
Debug-DevSafe -
-threadsCopySet the size of the engine thread pool (Source engine games)- Effect
- Takes a thread count; the default is 3. Setting it above the number of cores available does not help.
- Example
-threads 4
PerformanceSafe -
-freqCopyForce a specific refresh rate (Source engine games)- Effect
- An alias for -refresh; the wiki lists the two as the same option. Takes a rate in Hz.
- Example
-freq 144
DisplaySafe -
-wCopySet the window width in pixels- Effect
- Forces the game to start at the given horizontal resolution instead of the saved or auto-detected one. Pass -h as well to set height explicitly; on its own, height is derived from the aspect ratio.
- Example
-w 1920 -h 1080
DisplaySafe -
-hCopySet the window height in pixels- Effect
- Forces the game to start at the given vertical resolution instead of the saved or auto-detected one.
- Example
-w 1920 -h 1080
DisplaySafe -
+fps_maxCopyCap the frame rate (GoldSrc, Source and Source 2 games)- Effect
- Default 300 (400 in CS:GO and the TF2 branch). Match your refresh rate, or a little above it. Do NOT use 0 on GoldSrc — it uncaps Source and Source 2 but runs GoldSrc at 1 FPS. Above ~1000 (100 on GoldSrc) the engine develops timing bugs.
- Example
+fps_max 144
PerformanceSafe -
-noforcemaccelCopyDisables mouse acceleration.Experimental -
-noforcemspdCopyDisables mouse speed forcing.Experimental -
-useforcedmparmsCopyExperimental -
-vulkanCopyUse the Vulkan renderer where the game supports it (only engines with a Vulkan backend — Source 2, id Tech 6/7, UE4)- Effect
- Forces the Vulkan rendering backend instead of DirectX or OpenGL. Only has an effect in engines with a Vulkan path; ignored elsewhere.
DisplaySafe -
-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 -
-noborderCopyRemove the window border (Source 2007 and later)- Effect
- Requires windowed mode — pair it with -windowed or it does nothing. Gives borderless-window behaviour, so alt-tabbing avoids the two-to-three second delay exclusive fullscreen costs. Source 2007 and later only.
- Example
-windowed -noborder
DisplaySafe -
-override_vpkCopyExperimental -
-enable_addonsCopyOverrides the game's content files with content foundExperimental -
-nojoyCopyDisable joystick support (Source engine games, except Left 4 Dead 2)- Effect
- Skips joystick initialisation, which can shorten startup. The wiki notes it does NOT apply to Left 4 Dead 2.
PerformanceSafe -
-nod3d9exCopyDisplaySafe -
-fullscreenCopyRun in fullscreen mode (Unreal Engine and Source games)- Effect
- Overrides a saved windowed preference. -full is the same option in Source.
DisplaySafe -
-h 768CopySet the window height in pixels- Effect
- Forces the game to start at the given vertical resolution instead of the saved or auto-detected one.
- Example
-w 1920 -h 1080

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.
