Bumped into an invalid link.

I can say Hyper threaded processors have no problems with timers, or at least none that I have ever noticed.

I doubt dual core cpus would have any problems either. I would like to see your code. Have you tried your code on any one else's machine?

I doubt there is a fundamental error in timers so I suspect it is yourcode that may be to blame or your particular computer. Do you have problems running other games?
