I''ve recently been looking at porting old glide code to OpenGL and hit a problem I''m hoping someone can help with. One of the programs provides visuals for music but when I try to draw too much, instead of just slowing down GL does it''s mad framerate switch and the visuals appear to double in speed. It looks shit. Slowdown is acceptable - synchronisation can be picked up again later, is there a way I can turn this feature off? Any other suggestions about how to keep sound/visual sync spot on would be gratefully recieved. Peace. Geocyte Has Committed Suicide.

The glFlush function forces execution of OpenGL functions in finite time. But I think you should look at the program itself instead.

perhaps u need to sync to the monitors vertical refresh
on windows (4 nvidia card theres a checkbox in the disp[lay properties )
also theres an extension winswapinterval (example on my site)

rerad your post i think perhaps u need to have the program run the same speed on all machines (this has been answered heaps here and in other places)
