I actually was up at 2:00 am in the morning when all of a sudden i saw a patch being downloaded and insatlled. I loaded it up and then the 3D Vision light came on the reciever . I couldnt believe it. I loaded up a single player map because MP was down at the time due to the new patch. All i can say is they did a damn good job for the 3d in this game, when the sun glares on your face, or when a fellow soldier gets shot the blood flies in your face and gets stuck on your lense, when the dust is in the air grains are in your face, even when looking down the gun in iron sites...... 3d mode is truly nice. Its one of those games that they enabled 3D but didnt overkill it like most game do and it ends up becoming a bad experince. BUT!!!!! I have one 580 SC OC'ed to a core of 900, and i must say one 580 with no overclocking may not run this in 3d with max settings. Mine is currently OC'ed and it was playable but kinda suffered under large amounts of explosions or activity, but for the most part enjoyable.
Code:
3D Non-3D
Card Clocks FPS FPS
580 SC Batman Edition Stock 15-18 38-42
580 SC Batman Edition OC'ed 27-32 55-61
These readings were done at the games preset value of Ultra, im sure if you turned off MSAA it can become playable under stock settings. Hope this helps shed some light on the subject. If not looks like another 580 would be needed to fully 100% run 3d in max settings with no hicups.
