I just updated the drivers of my RX480 to the Adrenalin-Edition-18.4.1-Apr26 on windows 10 1803, and when I try to play FFXIV (dx11) in windowed mode with the fps limited at 60fps, it makes the game look/feel choppy/stuttering, I think the phenomena is called "frame pacing". The issue doesn't occurs when I play in full screen, and it didn't occurs with the Adrenalin-Edition-18.3.4-March23
I tried using a third party software to limit the fps after reading it could help, and it didn't do anything. Reverting the drivers to the 18.3.4 fixed the issue.
Anyone else experiencing this issue?
