I had the problem in Beta 6 where you had to set the resolution to get a good frame rate. Beta 7 had the same frame rate problem, but couldn't be fixed.
While running FMS_dbg_doflip.exe the frame rate seems to be fine. The other debug versions didn't make a difference.
I'm running WIN2K Server w/ an ATI Rage Pro video card and an ABIT dual processor motherboard (running Celeron 300A's overclocked to 450Mhz).
I would be happy to help with any further testing of any sort.
Thanks for making a great program!!!
