Turn off Nvidias Hair ... Suddenly 20 FPS.
Wow, turning off Nvidia's hair improved performance massively. Back to 40fps or so from 20s. Maybe I can bump up other settings now
Surprised you can max out the game at 4k with 970s considering they are close in performance to the 780s. The game is still absolutely gorgeous at 4k even with settings turned down.
To be fair, I've decided to play at a locked 30fps (as opposed to an unlocked 30-40 fps). I'm not rocking 60fps at 4K maxed or anything!
