uhm, actually 543 and 440 FPS isn't too much of a difference as running anything over 100FPS (or more like 85 or 75...) is totally useless... Aaand if you run as many less frames, the time BeginScene and EndScene consumes get less and less... At around 30 or so FPS you don't feel the diff at all

About versions... I've started DelphiXing with 1.05 and quickly changed to 06, and I've always used Delphi 7, so I don't really know what's the problem... What I do know is that 1.07 (after fixing those lil things I wrote down in the other topic ) is very good on Delphi 7.
