Stuttering video when recording at 120fps

[DerpyPig]

I need to use OBS to record at 120fps for good slow mo, but when I set the integer set value to 120 fps the video is really choppy, only displaying 1 or two frames. The audio is fine, and when I switch obs to record in 60 fps it is perfectly fine.

Your source is 59 (possibly 59.94) Hz(/FPS). I think you should record at that value. Your source is not changing 120 times per second.

I believe I have figured it out. Simply I dont think I can record 120 fps because I dont have a nividia card/ really high end specs
