I have R9 290x driver version 17.3.3.
I am using the DP connection.
I have tried it on GTA V, Mass effect 1, Alien Isolation. Fps its around 90 to 140. Which i believe is within range of this monitor for freesync to work.
But I still get tearing.
I have tried doing a factory reset.
disabling low input lag.
restarting the pc.
Its a shame as it is a really good monitor.
