Limiting the framerate during gaming can help to reduce the power consumption as well as it can improve gaming experience due to removing unwanted micro stuttering effect caused by framerate fluctuations. The functionality of expensive commercial video capture products is now available to everyone absolutely for free! There is no need to buy dedicated video capture software anymore!
