Re: Is GLUT hindering performance?

I don't think this is a GLUT specific problem. I had similar issues
with SDL. I realized that it uses up all the CPU cycles in order to
maximize the number of frames rendered per second. You can resolve
this by limiting the fps by calling some kind of sleep function for
some milliseconds after every frame rendered. In SDL, the function for
this purpose is SDL_Delay(). Hope this helps.
