Mine runs pretty badly on ultra settings, regularly drop into 20 fps, only game that's really performed badly for me so far. I've just downloaded the 14.6 beta drivers and not much difference if any. Anybody else struggling with their AMD cards?
i5-4670K 3.40GHz (Haswell) Socket LGA1150 Processor - Retail
Radeon R9 290 OC WindForce 4096MB GDDR5 PCI-Express Graphics Card
It runs brilliant for me.
To get a smooth experience i have the following settings, these were smooth on a 7970 and a 4gb 760 but are even better on my 290.
Res 1920x1080
Everything set to ultra
Hbao+
Max pre rendered frames 1
Vsync 1 frame
Msaa 4x (on the 7970 and 760 i set this to temporal smaa)
