This will however mean that when the screen updates it will get a scrabling of two frames. Also you will probably need to lock the math rate to something but the processor, like:
This will set the math to do 250 iteration per second, and the graphics will run as fast as your screencard can make them run, but not faster that the update rate.
timer=Millisecs() While Not KeyHit(1) timer=timer+4 ;do math If timer>Millisecs() Then RenderWorld() Flip True End If Wend
This will set the math to do 250 iteration per second, and the graphics will run as fast as your screencard can make them run, but not faster that the update rate.
