hi,
i downloaded the space invaders from the codebase. when i run it with the "windowed - full screen" option it runs pretty fast but when i run in with the "Fullscreen Exclusive Mode = 640x480/16" it runs pretty slow. is there something i should be doing or setting to make the Fullscreen exclusive Mode run faster?
thanks

here's the link to the codebase (i set sync rate to 0);

Fullscreen exclusive mode is simply much slower. There's nothing you can do to prevent it.

I also have a blog on how to make a game engine

fullscreen exclusive mode isnt slower. In fact I find it much faster and smoother.

The problem is the refresh rate cap. When you execute your program in windowed mode it will run at the maximum speed. However, when you run it in full screen exlusive mode, the refresh rate is capped at 60FPS or something.

Even when using sync rate 0, it wont go above that value.

That depends on your monitor's refresh rate. For example, if you have it set on 75, the framerate will cap at 75 in full-screen mode. Then again, you aren't going to need a framerate faster than 60 anyway. 60 is as smooth as you can get it.

I know, but somehow windows xp keeps directx from going over 60FPS most of the time.

It's called VSync
