Graphics feature	WSGF	Notes
Widescreen resolution		Some resolutions not listed; see Widescreen resolution.
Multi-monitor		Works, if `res(+fov)` is changed in console.
Ultra-widescreen
4K Ultra HD		Custom launch resolutions can be set inside an ini file; see Widescreen resolution.
Field of view (FOV)	Input `fov X`, `X` being a number, in the console to change your FOV.
Windowed
Borderless fullscreen windowed	See the glossary page for potential workarounds.
Anisotropic filtering (AF)	Textures are nearly nonexistent most of the time though.
Anti-aliasing (AA)	See the glossary page for potential workarounds.
Vertical sync (Vsync)
60 FPS	Game physics will malfunction at high frame rates, do not recommend exceeding 60, see High frame rate.
120+ FPS	See High frame rate.
High dynamic range display (HDR)	See the glossary page for potential alternatives.

Widescreen resolution

Many common resolutions are not available on the options menu.

Edit DefaultEngine.ini^[2]
Go to the configuration files location. Open `DefaultEngine.ini` Search for `[SystemSettings]` and Change ResX (width), ResY (height) and FullScreen values to the desired resolution values.

High frame rate

Forces standard V-sync on regardless of in-game setting, which prevents Adaptive V-sync, causes drops to 60FPS almost constantly (aka stuttering).

Game's physics will malfunction at high frame rates, recommend capping below value to 62 (i.e. 60FPS).

Change frame rate smoothing^{[citation needed]}

Go to the configuration files location.
Open UDKEngine.ini.
Search and change bSmoothFrameRate to FALSE or raise MaxSmoothedFrameRate value.
Save file.

For more information, see the Unreal Engine 3 page.

Issues unresolved

Crash when drawing loops or cubes

From the developer: "I am aware that the algorithm for this can go a bit crazy and cause the game to crash if you try to do it with large or dense structures."^[2]

Issues fixed

Crashes at Unreal logo
