max. frames per second

There is a technique called vertical sync (or v-sync) which guarantees that each frame of rendered graphics is only shown when the monitor is ready for it. V-sync essentially forces the engine to draw at the refresh rate of the monitor (unless it can't keep up with the monitor, in which case framerate will be lower than the refresh rate).

In game engines that do not use v-sync (it can be disabled in your graphics drivers and by specifically asking to bypass it via DirectX or OpenGL), the framerate will simply be as fast as the game can render.

Ok i understand. How do you enable/ disable vsync?
(For test app i use nehe framework)

Check out the WGL_swap_control extension if you're using Windows and the SGI_swap_control extension if you're running Linux.

thanks

That's only really going to be useful if you're using your game as a benchmark or if you're curious how much room you have to add load, though. There's no point in calculating frames that never get displayed.
