I have to agree, i have played the xbox 360 version and despite some AI issues and my hatred of using a gamepad for this type of game I was very impressed. Everything I have seen of the PC version has set off alarm bells though. The latest trailer for example is high res but the graphics look awful compared to the 360 and the game actually stutters even though it doesn't look like a next gen engine, in fact it looks thoroughly mediocre.
I hope I can be proved wrong, as on the 360 GRAW is wonderful, so immersive and visually stunning, really does the moden battlefield well.
