 I haven't looked at the source but it sounds like it might be using
::GetTickCount(), if thats the case it could probably be refactored to use
::QueryPerformanceCounter() which is a significantly higher resolution

 The idea of using the SDL wrapper for making a game is probably a good one
though.
