game speed issues

anyone tell me why this code runs fine in debug but jerky and slow when in fullscreen?

thanks

Replacing

Flip

with

Vwait:Flip False

resolves the problem. Although I haven't thoroughly checked your code, what was happening on my system was that the program wasn't running in sync with the monitor (1000+ FPS). This happens with some cards, as they don't have vsync enabled by default or it overrides whatever settings you want in Blitz when ran in fullscreen.

Not sure why this affected the speed in fullscreen though.

hi thanks that works fine now!!
