As a test, I used EVGA Precision's "K-Boost" to force my cards (in SLI) to run at max boost speed. There was no frame-rate improvement. Wth?!?
There's clearly something bad happening when in 3D mode, that prevent GPU scaling. For this reason, SLI is pointless right now.. but if it was fixed, I think SLI benefits would come into play @ 1080P for sure.

I still have the 3d vision disabling issue, happens mostly on highway or when flying a plane. Are you guys also still having this problem?

It's a 3d Vision bottleneck, if you run with 3d disabled in the control panel and use DSR to 4K you'll see the scaling is pretty good! I think it's due to 3D Vision stopping games from using any more than 3 cores, been meaning to do more testing on it but have got rather busy at work.

Something seriously wrong has occurred between updates for me. Everything is OK, except the shadows which are now completely at screen depth at all times. Both the official and Max payne 3 profiles.
No amount changing the graphics settings or restarting the game changes this...
grrrr.

I still don't understand why 1080p SLI scaling is so horrible. At 4k the scaling is amazing (~99%) but obviously too heavy to run in 3d.
1080p/1440p the scaling is just so bad that running it in 3d vision sucks to be honest. It was the same thing with dying light.
In comparison witcher 3 runs awesome in 1440p 3d vision maxed out. Perfect scaling.
If something runs perfectly smooth 60+ fps in 4k, I would expect the same performance in 1080p 3d vision. Unfortunately this is very often not the case. I can't really upgrade my pc any more for 3d vision. Going from 6 to 8 cores is useless and so is adding a 3rd titan because tri-SLI is not supported in 3 vision.
There are no more bottlenecks to resolve hardware-wise. Is it the 3core-bug? If so why is witcher 3 (or far cry 4)not affected?

Good point.. If Witcher 3 scales just fine (I'm going to try it now also) it suggests that NVIDIA may not be the culprit...but doesn't rule them out completely. At least we know R* is actively working the issues. Last patch included a 3D specific fix.
We may just need to be patient..
What is also interesting to note is that I can sometimes get the full 60FPS in 3D GTA V (I use VSYNC) but it is rare and usually when looking a wall or something stupid. I have also noticed that my GPU will occasionally boost, but not to the full boost amount. Hopefully it is just a matter of optimizing the 3D mode. R* was challenged to add every GTA V feature possible to the PC version and get it all right for launch...I can understand if 3D vision optimization just didn't rank high on the priority list...

For the performance not scaling with SLI- that's because for the games in question, you are CPU bound. Especially at 1080p where the graphic demands are lower relative to 4K, the CPU cannot fill the GPU fast enough.
This varies wildly from game to game, but older games tend to not support more than 2 cpu cores anyway. Dying Light and GTA5 are two that will support as many cores as you've got, which is why they show this problem in 3D.
(Pretty sure, not certain, the 3 core problem is not fully understood yet. I already reported it to NVidia.)

And thanks for that short explanation bo3b; which confirms my biggest fear: it's only going to get worse for 3d vision as new games need (and will need) more cores to run properly. Nvidia really needs to look into this. I can live with them not supporting our games since we have a commmunity which does a fantastic job at it, but once we face a core limitation issue in 3d vision the technology will completely die off in the future - unless VR can save us.

Is the 3 core problem just GTA 5 ? Some games like Shadow of the Mordor and Alien Isolation
3D vision is not that bad of a hit.
GTA 5 on my system when 3D is enable is I take 75 % hit .

My guess is (based on the above) these use up to 4 cores, and maybe not even optimally hence the performance hit of only having 3 cores available is much much smaller for these games.

To elaborate on this, [b][i]AMD CPUs[/i] [/b]are typically CPU bound in this game. We can see a lot of people are complaining about them with GTA V when you search for "GTA V GPU UTILIZATION" and they aren't even running in 3D. I don't have an AMD CPU personally. My 3D also works just fine in all the other games I play, no GPU scaling issues. This issue is quite specific to [color="orange"]GTA V in 3D[/color].
Let's focus on 3D specifically. I did some more testing and I can tell you with certainty that my GPU scaling issue is not due to being CPU bound. It is also not due to the 3-core issue either. I will show us.
I enabled some OSD monitors for the purpose of testing this. Below I have 3 screenshots. I just took them in a random location, I can duplicate the same results anywhere in the game.
[color="green"]First screenshot[/color] - Shows 60FPS is possible when graphics are simple, just to show 60fps is possible and not a hard cap. I can also get 60fps with people walking around me, cars driving, etc. The most important reason I show this screenshot is to compare the CPU/GPU utilization to the others.
[color="green"]Second screenshot[/color] - This time I am getting 37fps..Note that the graphics are a little bit more complex but yet the CPU and GPU utilization is essentially IDENTICAL to when I was getting 60fps. You add more complexity, [b][i]the FPS goes down instead of the GPU utilization going up.[/i][/b] My GPUs rarely even leave the BASE CLOCK (almost never boosts). Going from 60fps down to 37fps is a huge dip and very noticeable.
[color="green"]Third screenshot[/color] - Now I am only getting 32fps! The graphics are slightly more complex yet once again, GPU and CPU utilization hasn't changed! There's CPU left and PLENTY of GPU left. I've now lost HALF my fps and my GPUs and CPUs aren't working ANY harder??!?!
[b][i][color="orange"][b][i][u]So what is it common?[/u] Clearly, there is a CAP ON GPU UTILIZATION not a cap on FPS or a CPU bound issue, this is a 3D specific cap on GPU utilization and must be a Rockstar optimization issue.[/i][/b] [/color]
[/i][/b]
So in summary, [color="green"]when in 3D mode[/color], regardless of resolution, regardless of graphical settings chosen as the graphical complexity increases instead of additional workload being given to the GPU, the workload REMAINS THE SAME and the FPS is directly impact instead. That's pretty poorly optimized by any standard :) Try it yourself.
PS. I switched out of 3D, back to 4K and both GPUs are almost 100% utilization. I also tested at 1080P and get high scaling.

Third screenshot - Now I am only getting 32fps! The graphics are slightly more complex yet once again, GPU and CPU utilization hasn't changed! There's CPU left and PLENTY of GPU left. I've now lost HALF my fps and my GPUs and CPUs aren't working ANY harder??!?!
So what is it common? Clearly, there is a CAP ON GPU UTILIZATION not a cap on FPS or a CPU bound issue, this is a 3D specific cap on GPU utilization and must be a Rockstar optimization issue.
So in summary, when in 3D mode, regardless of resolution, regardless of graphical settings chosen as the graphical complexity increases instead of additional workload being given to the GPU, the workload REMAINS THE SAME and the FPS is directly impact instead. That's pretty poorly optimized by any standard :) Try it yourself.
PS. I switched out of 3D, back to 4K and both GPUs are almost 100% utilization. I also tested at 1080P and get high scaling.
