Yeah, well Uber Sampling is out of the question for me as well. I posted my specs a while back and was ridiculed when asked if I would be able to run Uber sampling with my setup and well, to those that said I could, you were wrong, way wrong.
Specs:
Sandy Bridge 2600k OC to 4.5
2xSLI 580's OC to 875 on the Core
8 GIgs of Ram.
With everything to max, I mean everything, plus Uber Sampling, I get around 35-40 in the intro, 30 or so in the intro "in-game" cinematics and finally gameplay, an average of about 20-25 or so.
Turning Uber off and everything left to Max, I am 60FPS in Cinematics, 60FPS in "in-game" cinematics and in game play, it flutuates between 50-60fps. I have Vsync on, so that locks the cap to 60fps, but it shows in fraps 61-62 at times. I have not made it to a heavly populated area, but so far I am averaging about 55fps or so, like I said, it does go to 50fps at times, just running around.
But, yeah Uber even with 580's in SLI is a no go. Here are some stats on the cards while in-game:
GPU Usage GPU1: 75 at the highest, avg of about 48 or so.**
GPU USage GPU2: Same as above **
Memory Usage: 955-965 of the 1.5GB on the cards
Heat: 73c on the top card/67 on the bottom card.
** Under "Uber" settings, the GPU's were at 98% on both for usage, even with that much horsepower, I was getting 20-25 in actual in-game and at almost 100% usage.
Yes, SLI is working for those that are wondering as both of my cards are being used together and at the same usage in ultra or uber settings.
So all in all, I think when they said a 590 for Uber, I think they meant 2 590's as 2x580's beat out 1 single 590...so yeah, that would be a beast and beyond of a rig to get this game at 60fps in uber settings.
