Currently I'm running it a bit higher than ultra with 4 samples of AA, and 4 samples of Anisotropic filtering with Shadows set to high and decal quantity set to medium, with Distant object detail set to high, and have turned off the object detail fade. All running on a 24' LED monitor with a true 1080p resoultion.
My PC specs are:
4 gigs DDR2 RAM
2.8 GHZ processor
WIN7 Home Prem. 64 bit
Raedon 5670 1 gig DDR5
I feel sorry for those poor chaps who dumped loads of money into a new PC to run this game ^^ Props to Bethesda for this fantastic game.
