Hi , I've been( programming in VGA )using allegro's Vsync to wait for
the blit() function, but isn't there a way to generate an Interrupt
when that vertical sync occurs? That way, I won't be wasting cycles
constantly polling with vsync( If that's whats happening .) Would such
an interrupt be present on most x86 hardware or  vga cards?
Regards
Hamilton
