frame rate query
Author
how come the frame rate is so high in fullscreen mode than in windowed mode?? Is it coz in windowed mode, there is lots of other stuff that needs to be drawn everytime, like the rest of the windows, desktop etc?
thanx
bye

Yeah, it is usually faster since Windows is not drawing all of its crap on the screen at the same time. When in full screen, windows is not drawing anything, so it is obviously faster. The only real exception is when you windowed peogram has an extremely low resolution (lower than the full screen at least), so it takes a negligable amount of time anyway.
Does the Screen refresh rate you set in the windows display settings have anything to do with the lower framerate when in windowed mode? Or are the frames totally unrelated, even in windowed mode?
That is just setting the default value for vsync. When you set the program to vsync (It usually does it automatically) that is the valuethat it will refresh at. You can override it with the presentation parameters structure, though. mHope that helps you out a bit. No matter how often you send the scene to the gfx card, it will only be able to draw at the refresh rate. That means that some of you frames will be discarded anyway. Don't get me wrong, high frame rates are still nice for other things.
