Widescreen resolution[edit]

Many common resolutions are not available on the options menu.

  2. Open DefaultInput.ini
  3. Search for ConsoleKey and delete the following lines:

    TypeKey=None
    You can also change the ConsoleKey to anything you want. Just replace None with what you'd like it to be.
  4. Load the game and press ~ or Tab .
  5. Type setres 2560x1440 or another resolution.

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.
