FrameRate Low

This is a problem with Vertical Sync. Your app normally runs at about 62, but occasionally it''s a little bit too slow and so it misses the retrace and has to wait for the next one, this halves your frame rate.

Also, as I''ve read many times on this forum, I would recommend using frame-independent movement. Base the rotation of your cube off of a timer of some sort, rather than what frame number you''re on (or rather than adding a constant number to the amount of rotation every frame). This will save you plenty of headaches later on with animation, I''m sure.

I agree with the frame independent method. Keep track, you probably already are, of how many milliseconds pass between frames. Then add a time dependent amount of units to your Radians variable based on the milliseconds.

// TimePassed assumed to be an unsigned long updated every frame.

// Radians assumed to be static float somewhere

// Rate assumed to be a static float somewhere, defined as radians to add per millisecond


Radians += (Rate*TimePassed);

If more time passes between render calls, you add more units to the Radians variable.

If you want 0.001f radians per millisecond, and 10 milliseconds pass, you will add 0.01f radians. It''s pretty straight forward. If you want to do it in per second basis:

Radians += (Rate*TimePassed*0.001f);
