char VideoForceFullScreen

fullscreen set from commandline

Next frame ticks.

int VideoSyncSpeed = 100

0 disable interrupts

Video synchronization speed. Synchronization time in percent. If =0, video framerate is not synchronized. 100 is exact CYCLES_PER_SECOND (30). Game will try to redraw screen within intervals of VideoSyncSpeed, not more, not less.
