[quote="bo3b"][quote="unstrain"]To end this conversation, here are some real tests I ran just now on my rig with 1 card vs 2way sli, vs 3way sli all with 3d vision enabled at 1680x1050, average (min-max): 3x GTX660TI SC 3GB
Valley Benchmark: 33.1 (7.1 (63.0), 56.2 (14.5-87.0), 64.8 (13.9-87.2)
Heaven 4 Benchmark: 22.2 (11.5-52.5), 45.4 (7.9-106.2), 47.8 (9.4-135.5)
Metro 2033 Benchmark: 28.58 (8.49-74.71), 48.08 (10.15-140.43), 50.35 (8.53-240.15)[/quote]
Awesome. I'm a big fan of hard data. Thanks for taking the time to test, and share it with us.
Followup question based on the data, if feasible:
Can you do another test where you specifically set PhysX to something different? The numbers are close enough, and all the benchmarks use PhysX, so it is possible that PhysX is freeing up headroom on the 2nd card.
Maybe try it with PhysX disabled. Or maybe with PhysX assigned to the CPU.
Or perhaps with it assigned to a specific card. In that case, if PhysX were the question, the bench results would be expected to be the same as your prior test.
Also, can you run at higher resolution? Maybe with oversampling.
At 1680x1050, it's going to edge uncomfortably close to CPU bound, with the GPUs not having enough work to do.
Still scales, but something seems off.

Yeah, that link led me to the 3-way Titan test. It definitely is fixed for 3D Surround.
I didn't find anything in forums on in Google searches that definitively says or proves 3-way is fixed in 3D Vision. Still seems like an open question to me.
Having the driver automatically setting the third card as a PhysX card makes it muddy.[/quote]

That thread there was started by me when I got my 3xgtx660tis, and the scaling is not that good, but the whole point of this thread here was that someone said is not scaling "AT ALL", which is different than "NOT WELL". I know I am starting to be CPU limited, because these lazy programmers nowadays don't want to do any optimizations for 6 or more cores available on the latest cpus... Pathetic , what can I say more. Also the NVidia driver is multithreaded in the last year, but the optimizations for that are far from significant lately. Adding that on top of the fact that NVidia is not showing much support for SLI and 3DVision lately (look how long until AAA titles are actually taking to work decently on the latest hardware). And all this, because we already paid for their latest products with the hope that the support will be on par, but that doesn't happen lately as was before. I don't see any major "The way is meant to play" titles advertised lately, AMD looks like is doing a much better job taking care of their hardcore gamers...
With all this said, yes, my old 3xgtx470s were scaling much better in 3dvsion than my $1000 3x660tis now. And I still have the 3x470s if anyone is interested.

I think what we really need, is someone from Nvidia to clarify this. As I stated before (and backed up with an 'official quote'), tri-sli was not previously supported in single screen 3d vision mode.
I doubt they will though!
I just don't want anyone to get too excited and buy a 3rd GPU for 3d vision based on this discussion. I think they will be very disappointed.

Ah, thanks for the info. With PhysX disabled, I agree with your assertion that 3-way SLI is working in 3D Vision. It looks like it's fixed.
The scaling is pretty weak though, but that could easily be a CPU limit on the relatively low-res screen. I sent you a PM with details that D-Man11 shared with me, if you want to try downsampling from 2560x1600.

you could run the benchmarks with 2-way sli at a low resolution to verify if you're cpu limited.
