    Just wanted to chime in here after lurking. First thanks to all of you with your help, tips, and information, it really helped out. So after months of trial and error and 2 RMA's, I am glad to say I have finally got BFV playing on 2 x 2080 Ti in SLI with DRT on the PG348Q STrix 3440 x 1440 in ULTRA settings and everything. I use the medium DRT setting for BFV because the ULTRA drops fps down to 50FPS in DRT intensive maps, (Rotterdam, etc...). It took alot of effort and money to get here, but there we are...

    So what CPU you're using?

    So after more testing I did determine that I was not actually getting DX12 SLI with DRX. Verified this with Rivatuner and confirmed it by trying out BF1 also. BF1 does not use SLI in DX12, but does work in DX11. I got such a performance boost when I enabled Dynamic Local Mode on the CPU that I attributed it to the SLI configuration. So hardware is there, just have to wait for more Software development to actually utilise it more efficiently. How long will we be waiting?

    DXR is DX12 only.
    DICE has already stated that DX12 mGPU is not happening.

    So you can have either
    Single GPU DXR w/DX12
    or
    SLI w/DX11.

    Well then it looks like the BF train may end with this release. No SLI support then why the NVLink? Just for miners?

    No SLI with DXR is only a DICE issue, other studios may have both together.

    Well if they stick with that (things do change), then it's DX11 and SLI for me. Seems a silly absolute stance to take; I'll bet they reconsider that one after a while.

    Thats maybe because your cpu is limiting .. so you need a faster one or try overclocking first..

    Hello,thanks for your answer but my cpu it's not limited it's using only 25% i have a i9 cpu i don';t have a problem with my video cards or my cpu the problem it;s the game or the drivers . This is why i was asking maybe someone knows how to make some settings in nvidia inspector or the game so i can get better usage from the video cards thanks .

    Only believe portion of what comes for toms, since bestofmedia took it over there are no real tech insiders left. Toms(bestofmedia is a malware infection) Be very careful

    The above is incorrect, BF1 mGPU support for DX12 has been patched in Lupkov Patch update - https://www.reddit.com/r/battlefield_one/comments/6v4rrv/lupkow_pas_update_patch_notes/
    I have 2x1080Ti and mGPU in DX12 works perfectly in BF1.

    My 2nd 2080 Ti stays idle, so no SLI/NVLINK support. PLEASE GIVE US SLI AND RTX FEATURES <3

    You know RTX works only in DX12 right? and that DX12 will never support SLI...You have wasted a lot of money buddy

    Never say Never, they will lose alot of supporters if they don't listen to the community. I know of many who didn't even get BF1 because of how the server administration got nerfed, (even worse than when DICE killed Map Modding).

    Dear lord, the amount of people who bought sli, who really shouldn't have...

    If a driver doesn't support sli out of the box, then you can just add a working profile yourself with nvidiainspector... and yes, this works fine with the 417.01 driver aswell...

    Sorry to say but the SLI community if very small ( and I used to be part of it) compare to the rest. Nvidia themselves advise to use single card setup now. Nvidia and dice will not invest a lot of time for a small group of people. I rather them be more focused on getting the game optimized CPU wise and better netcode.
