Hello, When I run my OpenGL-Demo apps in fullscreen mode, the fps is much lower than in window mode (e.g. 800x600:32, window: 105fps, fullscreen: 64fps). I am using windows xp and ati radeon 9000 with the latest drivers. Is this a common issue, a driver problem or something else? thanks,

You probably have vsync 'on' when running in fullscreen mode so it's all normal and okay. If this is not the case, then it may have something to do with drivers. Also, are you sure you're using exactly the same resolution AND the bit-depth?
