I'm confused. This says that GTX 680 (which is somewhat better than my 670, albeit mine is 4GB) should basically set everything to low.
Yet in the previous few pages people are claiming, all reassuringly-like, that a 670 should be fine at 1080p 30fps on "high" based on some videos.
I guess we'll see the truth soon enough....
A 670 isn't far from a 680 and if it or the CPU is overclocked that makes a big difference. Furthermore, as I state in the text, I used a pre-release version of the game with debug, logging, etc. Release version is likely to be that bit faster.
