On all the latest 17.x.x drivers I have been unable to get crossfire to work properly.
Both GPU's get to full usage 95% per gpu, but I only get 15FPS where I would be getting 60 solid (vsync'd).
Ultra preset with Hairworks off @ 4k res.
i7 6700k @ 4.5GHz
I've reinstalled the game, reset shader cache. Turned crossfire on and off. Changing Res and Settings has no impact it still sits at 15FPS. Complete reinstall of drivers using the clean install option. Disable all overlays etc, disabled freesync.
amdmatt how is it running for you on your FuryX's?
