Negative Delta Time Error In Dual-core Based Systems

Updated about 6 yrs, 1 mth ago (March 10, 2008). Know a better answer? Let me know!

Negative delta time!

Experiencing the error “Negative delta time!” when playing Unreal Tournament or a game based on its engine, on a dual-core processor, and/or under Windows XP/Vista?

 

Solution

To fix this:

  1. Right click on the main game application. The location of this will vary from game to game.
    • For Unreal Tournament, this will be an application called UnrealTournament.exe, in a folder called System, in the folder you installed Unreal Tournament.
    • For Unreal Tournament 2003, this will be called UT2003.exe, in the same location.
  2. Choose the Properties option.
  3. Click on the Compatibility tab on the menu that appears.
  4. Put a check mark in Run this program in compatibility mode.
  5. In the drop box underneath choose Windows 98/Windows ME.

If you are using an AMD processor, you may also want to get the Dual Core Optimizer from http://www.amd.com/us-en/Processors/ ... 18,00.html, which should also correct this problem.

For those curious, this is a result of unsynchronised time stamp counters in multi-core processors, and is normally not a problem as Windows handles this, but some games bypass the Windows API and directly access processor functions for performance reasons.
