I have code refreshing at roughly 60frames per second (little bit more then that since floats arent perfect) and i notice some bad flickering SDL video has been inited with SDL_SWSURFACE | SDL_ANYFORMAT. I only call SDL_Flip() once per frame and i sleep directly after the line. (Then poll the SDL events). The windows version doesnt flicker at all. Did anyone else get that problem? i am on an intel mini using the curent CVS source (i dont know how to make a framework, so i directly include headers and libs with xcode).

Use OpenGL and manually turn on vsync.

Specifically:

Code:

#include <OpenGL/OpenGL.h>

...

    // Call this once, after you have already have a valid OpenGL context.

    long swapInterval = 1;

    CGLSetParameter(CGLGetCurrentContext(), kCGLCPSwapInterval, &swapInterval);
