I have some troubles with my freesync monitor. I am running 4K with displayport 1.2 and freesync is on in the monitor menu and Catalyst panel. I have made sure that the monitor is on game mode too. When i game and it hits under 50fps it feels like the freesync stops working or maybe around 45fps. Is it really that common for a monitor to only have 10-15'ish Hz were the freesync works? Or did my GPU have to many beers last Friday. All my games are running full screen too. Using lates driver, and apparently a monitor driver i found on Samsung site for my monitor?!
