Did it get better? I was wondering when I saw that you have a GTX 570, and that got me somewhat nostalgic. Tinkering with Fermi's joke of a framebuffer and related stutter and corruption issues arising from the lack of video memory is definitely something I do not miss from my old setup with 3-way SLI GTX 480.
You see, that's a mighty decent graphics card even today, but I cannot stress enough how much it's starved of video memory. This is from personal experience, and the inherent cause of my incessant issues with stuttering and at times, graphical corruption in many titles, that led me to just say damn it all and go all out with the Titan, that efficiently and swiftly crushes 4 of my ol' trusty 480's. My advice here is keep VRAM 100MB below maximum for every GPU, in your case ~1200MB usage.
That fixed SLI scaling, stuttering and corruption issues on all titles back when I had to deal with 1.5 GB limit.
Of course that is a problem in some games (as it would be the same with a single card if you were threatening to constantly go above your VRAM threshholds).
I was more talking about testing for graphical corruption (which is a driver problem) than a profile, framebuffer, or fermi problem.

I know, bro, just that it could be a possibility, you see NVIDIA doesn't actively develop these cards anymore despite still having regular driver updates. I don't get any graphical corruption on my cards atm, though they are all Kepler both on my desktop and my laptop. Glad you managed by.
The remaining 2 of my 480's are currently with my brother, and the only other cards I could test atm are a pair of archaic 896MB GTX 275 GPUs. Not sure if it's even worth bothering lol.
Could you perhaps load up the newest drivers and post some results for me in DX11 in NS2?
Namely, when you load up biodome and walk around the start area whether or not shadows flash in and out randomly?
It would look like this:
That would be really helpful to figuring out the cause of the problem. Because if you do not get it, that means the driver regression is only with fermi based cards.
i'm running the new drivers on my 560TIs. I can check for that biodome problem this weekend. anything else? How can I capture these problems aside from screenshots?

Sadly no I don't, I wish I could afford two GTX Titans though :P

The problem is not just on biodome.. but with the shadow rendering in general (apparently just for me).
Screenshots should be fine, but videos made with FRAPS, Afterburner, or gifs made from videos also help.
Basically any evidence is fine.. even your anecdotal story!
Thanks for the help btw. I wish some people with SLI kepler cards would come in and talk about the SLI DX11 experience. The larger the sample base the easier it would be to narrow down the problem.
I strongly recommend MSI Afterburner. It's free, it has unlimited recording and screening capabilities with no watermarking and overclocking/voltage/fan control for your cards. It's a must have, bro
Tip to always keep your SLI setup quiet after you played for a while, max out the fan speed for a minute and then put it back on automatic, it'll "flush" the heat out

I've been doing that recently since one GPU will reach 102*C and about 95% load while the other is cool and around 30% load. I'm going to dust and rotate the cards since the slots are so close the top card's fans get blocked.

yea that's a really good idea, your card shouldn't go above 80 on a full load.

I can confirm the shadow flickering problem as well. This is with:
Awesome work guys. That means the SLI problem is both for kepler and for fermi (and Nvidia must not have really tested the game fully).
These problems do not occur if one uses 327.23 btw, so that means something changed in the driver. It also means that it is reproducable in both Fermin and K104 Kepler cards.
So has there ever been a resolution to this issue? I just got a 2nd GTX760 4gb today, got my SLI all setup and am a bit disappointed to see the flickering shadows in NS2. I'm using the 331.93 driver with win8.1 x64.

In the next few days I should be in contact with my contact @ Nvidia again (lost contact due to a temp ban on GAF recently).
In the mean time, play in DX9, or roll back your drivers to 327.23 or whatever the 327 driver was. Then edit the DX11 profile bits to be the same ones used for DX10 Crysis.
Update. My contact @ Nividia dropped off the face of the earth. I contacted Max and am waiting on some communication with him. I also filed a bug report over @ Guru3d which is then sent over to Nvidia.
Really wish I could move more on this... but alas, my Contact is gone
Am I doing something wrong here? I'm running an alienware 18, sli 770 gtx, and I still drop below 30 frames towards the end of a game when everything is hectic. I can remedy that by lowering settings. Although, I can run BF4 on ultra and never hiccup once. It's frustrating because, well, NS2 is far superior in every other way to BF4. I just don't know why it seems to run like crap sometimes.
Make sure you have preferred high performance set up for the NS2 profile in the Nvidia Control Panel. Other than that it is hard to do much about end game performance. NS2 requires extremely high single core performance, Laptops cannot achieve that due to heat concerns.
Just so everone knows... the latest Nvidia drivers still do not fix this problem. I still, of course, highly recommend using 327.23 with the custom SLI bits in DX11.
Comments
I need to have people test out the new driver with different rig configurations. Like 500, 600 series SLI.
On my system, I still get graphical corruption in DX11... but the Nvidia guys cannot reproduce it on their machines.
Therefore! We need a larger sample size than just myself. Could I please get some volöunteers?
The newest driver they just released is 331.82 WHQL.

works fine with them off
Edit, guess it just depends where you stand
- 3 x GTX680 4GB
- Driver 331.58
- DX11 SLI flag 0x000200F5
Edit:Shadow flickering also happens with
- 0x040200F5 (Nexuiz)
- 0x080202F5 (Batman: Arkham Origins, Batman: Arkham City)
- 0x000600F5 (S.T.A.L.K.E.R.: Clear Sky)
It's like it's a Z-fighting issue, but just for shadows.These problems do not occur if one uses 327.23 btw, so that means something changed in the driver. It also means that it is reproducable in both Fermin and K104 Kepler cards.
Good good. I will notify Andy.
Awesome job again, and thanks for doing all this!
Right now having a little trouble getting ahold of Andy, but it should come through in due time.
I'll update the thread as soon as I get a response!
