I need a better way to synchonize my FPS. currently I have a Start_Clock(); at the top of my main game loop and a Wait_Clock(33); // As per lemothes book at the end of my main game loop. Leaving this in makes the game look and run much worste and Im inclinded to think that its because it negates the benefits of triple buffering. ie if Im waiting for .12 seconds i loose that much time writing to backbuffer #x. Is the only option to use some sort of multi-threading, suggestions? thanks Lep
