Hioctane123: With update 1.3 I was getting serious screen tear even though I was gettting 60+ fps. I played with all the settings and nothing changed. I knew it had something to do with Vsync so I turned it off, no joy. I tried locking the frame rate in Radeon settings app, no joy. Then I noticed a setting in the gaming tab global settings for verical refresh called Enhanced Synch (never heard of this before). When I turned Enhanced synch on I got a FPS improvement of +20 and the screen tearing stopped.
Hope this helps someone else.
Yes, "Enhanced Sync" is an AMD option available on the RX480 and later GPUs (been out for awhile, now) that allows you to run at ~90% the speed of vsync-off, while reducing vsync-off screen tears by ~90%. If you have set some or all of your global settings in the Adrenalins to "override application settings", then no matter what you select from within the game, the GPU driver will override that to what you have set in the drivers, either globally or in each of your game's profiles. If you set an option to "use application settings" then the in-game setting will be the one used.
Not really sure what happened to you beforehand, other than to say you might have gotten your GPU-driver global settings confused somehow with your in-game settings, but enhanced sync seems to be doing exactly what it is supposed to do.
