Er, I can believe GDI BitBlt is 30ms, which is 33 fps surely. 1000/30 == 33 ish.<br><br>Of course you wouldnt get 33 fps because the game would have to be doing other things too.<br><br>Maybe it is less though, the only way to be sure it to time it yourself
<br><br>You can easily get 10ms for a fullscreen copy with a pixel by pixel copy in c++, and about half that with some optimization. Obviously to get exact figures it needs proper timing trials, but there is certainly no doubt that GAPI is faster than GDI by a large margin.
