How would this game run with an i7 4770k at stock speed with an R9 280x?
I have 3 setups at home:
1) 780 SLI (2x Galaxy HOFs) + 4770k (All Stock)
2) 680 (Non SLI) + 4670k (All Stock)
3) 280x (Non CF) = 3770 (non-K) (All Stock)
1) The 780 SLIs run the game at 1440p (90hz) max everything (Ultra) really well, except when getting into a car and the system loads up the rest of the world. Other than that, it's butter. (27" inch LED display)
2) The 680 is running it at 1080p (60hz) on High is also butter except for the car thing again. No Ultra quality textures / shadows. It gets 50-60fps no problem. The game looks great on a 48 inch TV.
3) The 280x is at 1600x900 (60hz) on a 20 inch display. The game is butter at that resolution with a 3GB card on Ultra.
Everything above is running with Vsync off. I am now testing with Vsync on and it's not going too well, can't get it to 60 fps consistently so it locks itself at 30...There is a nice bit of tearing with Vsync off.
Over all, the game scales well. The link posted in the reply above (Techspot) shows a 660ti running it at 45fps on High at 1920x1200. Overall a good experience but the stuttering needs a patch.
Now...is it actually a good game? I don't know yet. I'm still playing with the hardware...
