slow game

What would cause my game to run slow? Sometimes its super fast, fast, normal, and unplayable slow. Its being created using the Windows API. http://cboard.cprogramming.com/showt...threadid=43291
In this old thread you can find an old version which had the problem then. This means the game wasn't slow from storing masks, but instead from some other cause.

did you include a timer function that controls framerate so that the games engine is frame rate independent(such that you would move the same distance in the same time on different speeds?)

Have a look here (' Achieving Frame Rate Independent Game Movement ')
