I used frame skip 7 and 8 just for fun and i was very surprised to discorver that Wipeout 3 and in particular Ridge Racer 4 runs really smooth. I was expecting a choppy frame rate but no, it's really smooth. Maybe frame skip works in a different way and not as i thougt...

Try frame skip 7 and 8!

EDIT: Same occurs with diablo, really smooth framerate with frameskip 7 or 8. Maybe frameskip 8 (17-18) skip a frame every 17-18...but only smoku can say that. It's awesome!

EDIT2 (the revenge): Incredible speed boot even with gran turismo with frameskip 8. Guys it's really smooth!
