Hi there, How do I go about calculating the frame rate of my code? Obviously it''s the number of frames updated per second, but where-abouts (and how) in my game loops is this figure calculated. Also, can anyone point me at some information about locking the frame-rate down to a fixed level. Many thanks, Eight

You can calculate your framerate like this, in pseudo-code:

TimeCur = 0;TimeLast = 0;while(GetInput says not to quit) { TimeLast = TimeCur; TimeCur = GetCurrentTime(); TimePassed = TimeCur-TimeLast; Output("Your frame rate is %f.", 1000.0f/TimePassed); DoSomething(); Render(); Flip();}

NEVER lock your frame rate! Just have it so that everything moves/happens at a rate perportional to the time that has passed. If you lock your framerate, to give crappy looking performance to good computers, and you cause even bigger problems for the people who can''t keep up with that locked frame rate.

Ah right.

Simpler than I thought. I feel thick now.

Thanks for the help Null.
