Been eagerly awaiting this title, however I am just looking for feedback from others with Multi-GPU systems and see if it has SLI support. From what I am gathering, the answer is no or limited, however that was not a good source. From what performance numbers look like for this game, I'd be disgusted to see it not have day 1 SLI/Crossfire support knowing how demanding it is and how much it could benefit from SLi/Crossfire. But knowing how the industries state of affairs......it would not surprise me if SLI/Crossfire were both non-functional. Anyway hope to hear feedback from those who have tried.

No problem. Yeah, it is sad. The game really does need sli support.

Yeah read Guru3D's work in progress, and the entire time thought "Hey my 1080's should really put up a good fight and really make this game look good". Wrong again LOL! 2x 2080Ti's would be AMAZING!!!! if only.

Yup. Vulkan or DX12 . No SLI ... Played few minutes in chapter 1 and closed the game. forget ultra or high with 1080 Ti . Even 1080 Ti will struggle to keep it running at medium with steady 60 FPS... at least for me because I game at 3440x1440.
Really disappointed with this.

@ joey unfortunately SLI is on it's death bed. Having said that from what I'm reading and seeing the game doesn't run as well on Pascal based cards for some reason. Probably something to do wit GamersNexus did a good GPU test https://www.youtube.com/watch?v=yD3xd1qGcfo&t=991s I'm getting 75-90fps in game with everything set to ultra except for motion blur which I don't like so I turn it off. I play at 3840x1080 on a 32.9 monitor. Game does look very, very good.

Should this work for 1080ti cards as well? Also, are you using the new NVidia drivers, or are you rolled back to a previous version? I've read others had to rollback to get SLI working, but I don't think they had to use a NV profile to do it.

Hello everyone and thank you Sajin!
However, does anyone knows how to add the "User Specified" values? I'm not finding those in my Nvidia Inspector so I guess I have to add them manually, right?

I’ll test this out tonight...hopefully it will work with 1080 SLI. I doubt it will work with TAA, it never plays nice with SLI.
Thank you in advance sajin!
Let’s hope an official SLI profile gets released soon in the meantime.

In NVIDIA Profile Inspector, "Export all driver profiles". Open file in a text editor, find the profile, and replace it with the one Sajin gave. Save it, and "Import (replace) all driver profiles" using that modified file.

How exactly does one create/import such a profile? The .nip files the Profile Inspector uses are formatted differently, and entering the IDs and settings into that format manually didn't work, so how do I import this?
I have found a different solution to get Sli working, but yours seems superior, so I'd love to know how it's done.
EDIT: Well, nevermind, I wrote this a minute too late.

Sajin. Would you kindly share with us how to do this from nvinspector ? Sorry I'm a bit of a noob when it comes to these things.
Edit: oh .. same didn't see the previous post. I will give it a shot.

Thank you, it worked! JustusLM, follow those instructions above. If you "Export all driver profiles", it gives you a .txt file that you can edit, just like uhwhiteguy said. Actually, it didn't get rid of my problem, which is that I have to enable TAA, otherwise the game world is blindly bright (and unplayable). Ultimately I'd like to disable it, as it only makes the game looks blurry to me, and take about 25fps... However, with the custom profile, I was about to enable TAA and gain 5 fps back. :)

Sure! Actually I have two GTX 970 (with a consequent OC). On a single GPU I run at about 45fps on 1440p with a mix of high/ultra and some options on medium without MSAA/TAA/FXAA. And with SLI I run at 85fps with the above settings. With TAA enabled however, I run around 60 fps. (Those numbers are relevant in the Heartlands though, didn't venture in Saint-Denis yet).
