You need to wait for the wait-retrace.. a litle piece of code, that waits
until the screen is blit to your videocard. You stick that code, right
before you update the screen after ll others things you handle in every
frame.
It will appear slower, however what you are really doing using wait-retrace
is make sure, the screen 'keeps' up to you speed. (in other words you slow
down, because the screen will otherwise mis an action you have done)
I'm sure some one still has the machine code wait-retrace routine on their
clipbord.
Most alternative graphics engine have it either built-in or provide it
through some routine.
