Negative Delta Time

  • Two Factor Authentication is now available on BeyondUnreal Forums. To configure it, visit your Profile and look for the "Two Step Verification" option on the left side. We can send codes via email (may be slower) or you can set up any TOTP Authenticator app on your phone (Authy, Google Authenticator, etc) to deliver codes. It is highly recommended that you configure this to keep your account safe.

It means that "last time - current time" is smaller than 0
You are traveling back in time.

These things can happen with overclocked or broken hardware.
Or it could be a bug in the runtime because of some special behavior of you CPU.

I was able to fix the Negative Delta Time! problem by running UT2003 in Windows98/ME compatibility mode.:D

And to do what uncover just said, right click on the game's shortcut, go to properties. There click on the compatibility tab. The add a check box to "run this program in compatibility mode for" and choose "win 98/me".
