Digital_CHE: Just for the record: This game runs fine at 1080p, with everthing at maximum, on my test machine with and Intel Core i3 4160, 2x4GB 1866, Zotac GTX 960 2GB, Gigabyte Z97X Gaming 5, Win 7 pro 64 bit...
Well, not 60fps, but it is playable at 30fps (because of the core i3). If I low the details at High, I have more stable FPS... Soon I'm gonna get a core i5 4690k (I can't afford more).
I'm running it on medium-high (some stuff on low, like shadows and water, some stuff on high-ultra like textures) a rig with a AMD A6-6400K (3.9 Ghz dual-core), 560TI 2GB OC and 8 GB ram.
I will upgrade my rig with a quad-core AMD soon (Athlon X4-860K, 3.7 Ghz).
Oh, fyi: I play on 1440x900 resolution (max resolution of my monitor).
