Nothing.... Whether I use 1 or 0, it doesn't make a difference. I have fps_max set to exactly 60 and fps_min set to exactly 10. No matter what I do, even with fps_min the same as fps_max, the frame rate for 60 goes to 32 with the fluctuations. With my original settings, it varies from 61 to 63. This is getting on my nerves

.... 61 to 63 isn't bad, but it causes jerks (as from processing 2 frames at once) which throw it off.
