At 1600x1200 things already change and shift towards the upper class of mid-range and more expensive graphics cards. Look at that HD Radeon 2900 XT go by the way. A warning here about the 2900 XT though (before you get too excited) there's a bug in the 7.9 Cats drivers we used and we noticed poorer Texture Quality in certain situations.
Indeed, a GeForce 8800 GTX is pretty much your minimum required graphics card at 1600x1200. For those that noticed, I ran that 8800 GTS 320 MB test three times to be sure including a re-installation of the driver, but the results matched time after time. I'm pretty confident it's a driver bug though.
this game ran pretty good on my 8800gts 640 mb and my system in the sig i ran it at 1600x1200 with the stuff on High, was the demo and i did the video test and it was around 30-50 fps
I though I read something about fixing the 320MB's performance hole in the 163.69 or 163.71 drivers. Gotta find that source.
The issue also involves the hotfixes for Vista, also found on Nvidias driver pages. You need all three, IIRC in conjunction with the 163.xx driver family to get rid of the problem. Oh and that Gamespot review is worthless too, no offense. They use different configurations of hardware and settings which tells you nothing except that they all misrepresent the game as performing at sub-40fps levels.
InterestingJust a note, ATI has released a new Cat 7.9 hotfix driver that improves performance in WiC - http://support.ati.com/ics/support/default.asp?deptID=894&task=knowledge&questionID=29837
We are working on our own roundup apples-to-apples performance article using this game and we will be using this updated driver as well.
