So looking back to the first post by Masterdeadly, I remember having this same issue a longggg time ago.. with fraps and as i've read though these posts i dont really beleive its been answered. Can you record while playing the game with more than 30FPS with any of the methods mentioned. Most people say its very playable at 30FPS, how ever for somone that plays a game running at a stable 125, 333 FPS sitting at 30FPS to try and record.. well its not even worth trying.
Sorry if i've missed something somewhere mentioning how you can increase that or a way around it but i dont see anything.
