Gonna second this. I use i5 2500K, 16GB RAM, 2x AMD 7970 (tried both with and w/o crossfire enabled). I still use Catalyst 14.4 however (last recommended stable release).
I think we are getting the same artifacts. I got a feeling that my artifacts increasingly comes when zooming out alot. Except for this issue and the – sometimes choppy performance – I’ve had no other technical problems after 50h playtime.
Anyone got suggestions?
