As the title says I am having issues running crossfire in fallout 4 under the new drivers. The game got a great performance boost from crossfire however anytime my fps gets near or above 60 fps I have huge amounts of screen tearing. the game plays great below 55 fps. Seems to happen the most while panning the camera horizontally but will do it vertically as well. I am using 2x sapphire 290X 8GB cards.
Is Vsync enabled?
Have you tried enable FRTC as well as Vsync and setting it to 59 or 60?
Yes VSYNC is on for the game and in crimson, I also at one point had FRTC set to 55 but I didnt try 59-60 as I am not too familiar with FRTC.
