See High frame rate.

Widescreen resolution[edit]

Many common resolutions are not available on the options menu.
Edit DefaultEngine.ini[2]
  1. Go to the configuration files location.
  2. Open DefaultEngine.ini
  3. Search for [SystemSettings] and Change ResX (width), ResY (height) and FullScreen values to the desired resolution values.

High frame rate[edit]

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]
  1. Go to the configuration files location.
  2. Open UDKEngine.ini.
  3. Search and change bSmoothFrameRate to FALSE or raise MaxSmoothedFrameRate value.
  4. Save file.
For more information, see the Unreal Engine 3 page.

Crash when drawing loops or cubes[edit]

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[edit]


Update PhysX[2]

Install the latest Nvidia PhysX System Software.
