Beyond this, turn off gimmicky 24fps. Low frame rates will only add to stutter.
People don't realize, your display need to be setup to handle 24fps for most sources. More than likely, whatever you're watching it in just converts it to 30fps and then doubles it for a 60hz refresh rate. Basically, unless you are recording to Bluray disc's or you have your PC to actually output 24fps (why? Lol) your not going to benefit. Beyond that, you still need a newer display that can actually support 24fps (refreshes at 48/72/96/120/240hz) and not just convert it to 30fps.
