In my DirectDraw app about one second anything moving has a little stutter and then continues along. This delay is very small but noticable. I''m not going to post any code since I have no idea what might cause this but I was wondering if this is a general DirectDraw issue or a common programming mistake. I know that without code this might be hard to debug but has anyone else had similar problems and found a solution?

I have a similar thing happening with OpenGL since I moved to XP. I don't know if it has to do with the operating system, the combination of tick time with the refresh rate on the monitor, or the video drivers. I had someone else try out the demo and he said it ran smooth with no hiccups.

So I guess try changing the monitor refresh rate to something higher for starters.

Yeah I''m using XP too and am wondering the same thing.

do you mean when you first start it that there''s a second where it''s kinda choppy then it moves like it should? or you mean it does it every so often when it''s running?

It only happens once like a second after the app starts. After that there is no problems.
