This title played solid 60fps on an old 7950 with the 14.x.x driver.
Plays like absolute crap on a Fury X, many threads on Steam and Reddit regarding problems with this title on these new Adrenaline drivers.
Can you please look into this AMD Team.
This fixed this issue with all DLC also. This allowed a solid 60fps experience with 16x AA which is outstanding.
Its the exact same issue with NV also.
