The reviews I've seen on www.guru3d.com suggest you need a MONSTER of a PC to run this game properly.
My ignore list: growing too fast to keep updating.
As I understand it, the PC version has been massively optimised for DX11. And if you can't do DX11, it's ugly. :P
I'm very tempted to buy this myself, although I'd grab it on Xbox. I love an atmospheric shooter, and I really like the setting of this game.
Think I may be giving this one a skip. The reviews are not amazing, and I have an overload of games at the moment. Maybe later if I get the time.
