I own freesync Acer monitor (48-75hz freesync range) and when any game has for example: 60 fps (or whatever fps between freesync range) then it falls back to 75hz (which is max frame rate of my monitor) and then framerate changes to this one in game, and it happens all the time, 61 fps - 75 hz -61 and again and again. It should stick with fps in game... right?
