First off, thanks for the excellent salutation :)
Donuts is actually a DX demo, and was ported to euphoria by Todd for
Exotica. I tried to maintain all his demos as accurately as possible,
and the demo didn't originally have frame skipping. Donuts will run
slower on old machines, and extremely fast on newer ones. I'm not sure
why MS wouldn't have added frame skipping, it's not hard at all.
Look at the FPS_rate.exw demo to see how to moderate the frame rate, so
it will skip when the frame speed drops below the set FPS rate.
You will have to add equations for frame skipping to all the places
within the donuts demo where the position of a sprite is updated.
(I don't think it's worth your time though ;P)
My fps routines do work, but I'm not particularly satisfied with them.
I haven't done any extensive testing, but when frame skipping is done,
graphics seem to freeze for a moment, or speed up dramatically, when the
FPS rate fluctuates too much.
You could make your own frame skipping routines quite easily using win32
timers, and I think it would be more accurate than mine.
