 Welcome to my 3d vision coverage of the gtx 580. So I'll be running the gtx 580 Against the gtx 480 as well as to gtx 460s in SLI so I'll be running both single and dual configurations in SLI with the 580 and Finding out how the stereoscopic 3d element of rendering the game impacts the performance So the settings I'm going to be using are here, and I'll be wearing these slick glasses this is the settings I'll be using for graphics are here and That is what they are Stay tuned for more All right, so I want to talk about the methodology a little bit with the Testing on all of these different cards with Call of Duty black ops in 3d vision surround so the first thing you're going to notice right away is that B-sync seems to be enabled now I Believe it's to do with 3d vision although I could be mistaken, but despite disabling v-sync and Both on the driver level and in the game. It looks like we're still capped at 60 frames per second now My my suspicion is that that's to give you a better overall More smooth 3d vision experience because if your frame rates kind of going all over the place Then it might it might screw up the alternate frame Vision that you have with each of your eyes, so okay Mason over. Oh there we go okay, so Basically what we're not going to be able to look at is minimum or is maximum frame rate Because the maximum frame rate is going to be 60 for all of the cards So we'll have to completely ignore that but I believe that the average frame rates should still be somewhat relevant Because you'll see you're not seeing much of it here But in the action sequence that I actually benchmark I use the same benchmark that I did for my non 3d test In the action scenes that I actually was using for benchmarking it actually goes quite a bit below 60 very frequently That's disgusting anyway. That's all I wanted to say about the methodology So in conclusion Really any one of these configurations is perfectly acceptable for playing call of duty black ops in 3d on a single 1920 by 1080 monitor now one thing that we did notice is that Running at any of the single card configurations showed a much lower dip in minimum frames per second versus SLI now because We were capped at 60 frames per second. We weren't actually able to see the cards separate themselves out away from each other in terms of average FPS as much as you'd normally see if you can find a way to Turn the v-sync off So yeah, since there's nothing we could do about it it makes all the cards look kind of close together But what you really want to look at is that minimum frames per second because that's where you're going to separate The men from the boys so to speak so thank you for checking out our little coverage of the 3d vision Experience in call of duty black ops and so maybe I'll just get back to the game now.
