why do games lock at 60 or 30 fps, why not inbetwen? 40fps? 50fps? is there something am overlooking?
I think the only reason for frame rates of 30 or 60 fps is the american analog television system NTSC (approximately 29.97 FPS).
Perhaps most game developers thought that if 30 FPS is fast enough for television, it also must be fast enough for video games. Later when the graphic cards became faster they doubled the frame rate to 60 FPS.
No, my first reply has the answer, and Bart elaborated with screen-tearing.
why do you want to do less than 60? Do you not use time_step to make your game fairly framerate-independent?
Because your graphics card will live longer and consumes less energy when you lock your framerate. Why do you want to torture your graphics card with for example 120 FPS, even though 40 FPS is fast enough for your game?!
The framerate you use for your game depends on the type of your game. Only if you use very fast movements in your game (for example in racing games) you should use high frame rates.
If you aim for less than 60 fps you'll get 30 fps or lower in fullscreen. The fact that 60 fps is a
problem implies that the game isn't framerate independent, which I was just confirming with him.
