00:00:00,640 --> 00:00:11,480
welcome to my 3D vision coverage of the GTX 580 so I'll be running the GTX 580

2
00:00:06,560 --> 00:00:14,200
against the GTX 480 as well as two GTX

3
00:00:11,480 --> 00:00:20,720
460s in SLI so I'll be running both single and dual configurations in SLI

4
00:00:17,039 --> 00:00:24,119
with the 580 and uh finding out how the

5
00:00:20,720 --> 00:00:26,760
stereoscopic 3D element of rendering the

6
00:00:24,119 --> 00:00:32,279
game impacts the performance so the settings I'm going to be using are here

7
00:00:29,640 --> 00:00:37,399
and I'll be wearing these slick glasses uh this the settings I'll be using for

8
00:00:34,719 --> 00:00:41,600
graphics are here and uh that is what they

9
00:00:38,120 --> 00:00:42,760
are so this is learning so to me stay

10
00:00:41,600 --> 00:00:47,719
tuned for more all right so I want to talk about

11
00:00:45,039 --> 00:00:53,960
the methodology a little bit with the uh testing on all of these different cards

12
00:00:50,520 --> 00:00:55,359
with Call Of Duty Black Ops in 3D Vision

13
00:00:53,960 --> 00:01:00,920
surround so the first thing you're going to notice right away is that bsync seems

14
00:00:59,000 --> 00:01:06,600
to be Ena now I believe it's to do with 3D Vision

15
00:01:04,040 --> 00:01:11,360
although I could be mistaken but despite disabling vsync and both on the driver

16
00:01:09,799 --> 00:01:16,400
level and in the game it looks like we're still capped at 60 frames per

17
00:01:13,240 --> 00:01:19,119
second now my my suspicion is that

18
00:01:16,400 --> 00:01:22,560
that's to give you a better overall more smooth 3D Vision experience because if

19
00:01:21,280 --> 00:01:27,840
your frame rate is kind of going all over the place then it might uh it might

20
00:01:25,040 --> 00:01:34,600
screw up the alternate frame Vision that you have with each of your eyes so okay

21
00:01:31,119 --> 00:01:36,520
Mason over oh there we go okay so

22
00:01:34,600 --> 00:01:41,399
basically what we're not going to be able to look at is minimum or is maximum

23
00:01:39,240 --> 00:01:46,759
frame rate because the maximum frame rate is going to be 60 for all of the

24
00:01:44,280 --> 00:01:51,600
cards so we'll have to completely ignore that but I believe that the average

25
00:01:49,560 --> 00:01:55,840
frame rates should still be somewhat relevant because you'll see well you're

26
00:01:54,399 --> 00:02:02,640
not seeing much of it here but in the action sequence that I actually Benchmark I use the same Benchmark that

27
00:01:58,759 --> 00:02:05,119
I did for my on 3D test in the action

28
00:02:02,640 --> 00:02:09,560
scenes that I actually uh was using for benchmarking it actually goes quite a

29
00:02:06,520 --> 00:02:11,840
bit below 60 very frequently that's

30
00:02:09,560 --> 00:02:14,480
disgusting anyway that's all I wanted to say about the

31
00:02:16,640 --> 00:02:22,400
methodology so in conclusion um really

32
00:02:20,640 --> 00:02:28,800
any one of these configurations is perfectly acceptable for playing Call of

33
00:02:24,640 --> 00:02:32,239
Duty Black Ops in 3D on a single 1920x

34
00:02:28,800 --> 00:02:34,879
1080 monitor now one thing that we did

35
00:02:32,239 --> 00:02:40,159
notice is that running any of the single card configurations showed a much lower

36
00:02:38,000 --> 00:02:45,120
dip in minimum frames per second versus SLI now because we were capped at 60

37
00:02:43,400 --> 00:02:49,560
frames per second we weren't actually able to see the cards uh separate

38
00:02:47,599 --> 00:02:54,159
themselves out away from each other in terms of average FPS as much as you'd

39
00:02:52,200 --> 00:02:59,360
normally see if you can find a way to turn the vsync off so yeah since there's

40
00:02:57,800 --> 00:03:02,200
nothing we could do about it it makes all the C cards look kind of close

41
00:03:00,879 --> 00:03:05,720
together but what you really want to look at is that minimum frames per

42
00:03:04,239 --> 00:03:10,599
second cuz that's where you're going to separate the men from the boys so to

43
00:03:08,599 --> 00:03:16,480
speak so thank you for checking out our little coverage of the 3D Vision

44
00:03:13,799 --> 00:03:20,480
experience in Call of Duty Black Ops and so maybe I'll just get back to the game
