After some experimentation, it appears that the FPS Optimizer works pretty well. Thanks for the hint about resetting the MaxFPS in the .ini file. The help that accompanies the program is good as far as it goes, but it doesn't go far enough, in my opinion; some controls (like Changing Speed, and whether to use Linear or Quadratic Acceleration for auto adjustment) simply aren't discussed. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
