[Vrzone] GTX 680 SLI Preview - Page 22

post #211 of 290
So, is there any other evidence besides that Tom's article that 3 cards reduce stuttering?

My theory for them believing it does (they even state they weren't sure why) is because 3 cards generally runs at a higher FPS than 2. 3-way SLI is probably getting 60+ FPS in every game, so microstuttering is less noticable. Whereas, 2-way SLI will dip into those 50s, and 40s in those demanding games and will make microstuttering much more noticable.

I've personally never consider microstuttering a problem until I get a game that I can't run a sustained 60+ FPS. As soon as I hit <55 I really start to notice it. It's like 60=60, but 55=20.

Yeah, makes sense. It's unfortunate since 1 card is generally not enough to max settings on 2560, 2 cards produces microstuttering (when you play a game that you actually need 2 of them, it seems like that's exactly when it'll dip <60), so 3 would be ideal. But then 3 cards is also going to be the most troublesome to sell whenever the next generation comes out. Zzzz

Eh? Do you have 4-way crossfire and 4-way SLI setups to make such a statement or are you just repeating what someone else has told you? Last year with my 4-way 3GB 580 setup I was seeing upwards of perfect scaling in SLI with some games (and no one knows yet with 680's):

483


As for micro-stuttering; just like the Tom's hardware article concludes, I think SLI has less stuttering versus cross-fire. I keep my FPS minimum always above my displays refresh rate with some serious GPU power so if it does micro-stutter, it is almost imperceptible. On both setups though I find SLI keep's it a bit smoother than cross-fire in regards to micro-stuttering.

I really wish more developers would take advantage of PhysX as it really makes a big difference in the games that support it....

You mean you hope more developers get paid by nvidia to use physx...
IMO developers should use DX11 for physics. That way everyone gets the same support.

It seems to me that 3 and 4 GPUs do actually eliminate micro-stuttering, at least based on that Tom's study (using HD6870s on a few games).

Framerate for 3 and 4 GPUs are high but this is not the main reason that makes the micro-stutter less noticeable. The main reason is that but the graphs are almost just as consistent as a single GPU (ie not choppy and fluctuating).

Tom's offered no explanation.

I wonder why.confused.gif

It's probably because they average each other out. Like in dual if one is at like 70fps and the other 40 fps it stutters, but if in quad there's one at 40 one at 70 and one at 60 it doesnt seem so bad maybe because theres 3 or 4 different cards. Idk this could be a possible solution though

Looking forward to these!

Can't wait to see how these perform on Battlefield 3 not to mention new games this fall. I'm hoping this can really push over the limits for the new stressful games of 2012 later.
