    Is it dx11 or dx9?

    Nevermind, it's dx11, I rember I put my reshade config with dxgi naming in it ;)
    I find nothing yet, will investigate in the weekend.

    This is UE4, right?
    You might want to try "0x080020F5" with TAA disabled.

    Anyone found SLI flags for Skyrim SE?? Now that I have loaded a lot of visual mods I get parts where it can't hold 60fps anymore on a single 1080. Would be awesome to actually use my 2nd gpu for a solid 60fps everywhere.

    I finally found flags that has no visual bugs at all... however there is negative scaling and runs a bit worse compared to a single GPU. I'm not sure what other bits I should change to try to improve scaling at this point. Messed around trying different bits randomly and nearly everything else I tried ended up with flickering shadows or messed up Bloom.

    0x080001F5

    Anyone found something working for Cities Skylines?
    I see that there is many posts about this on internet and many suggestions but nothing seem to work consistently.

    I don't own Cities: Skylines, but regarding other Unity engine games I have had success in using the -force-d3d9 launch option and using the basic "0x02400005" profile.
    A good example is Dead Effect 2, which I tested a while back:
    https://www.forum-3dcenter.org/vbulletin/showpost.php?p=11134394&postcount=2322

    Could you please list all your settings and resolution?
    Cities: Skylines is well known for being quite CPU limited at lower resolutions.

    Which DX11 SLI profiles did you actually try, and did you see any scaling at all?
    Screenshot comparisons with FPS numbers would be useful to clear all of this up (Single GPU vs. 2-way SLI).

    i tried a lot of different bits for the hunter call of the wild,and the killing floor 2 bits scaling well but its flickers like hell.all the other bits was worse.the game use the next generation of the avalanche engine(just cause 3).any idea?

    This is at 4K resolution?
    Could you please post all your settings, as well as single GPU vs. 2-way SLI performance numbers?
    It could be possible, that one of the more simple AFR1 modes might do the trick.

    Try out "0x000000B5" and "0x080000B5".

    Hello, everyone.

    I'm new here, and was wondering if anyone could tell me if there are better sli bits for Dragon Ball Xenoverse 2 then this one "0x281080F5" found by Zyrusticae over on Steam Discussions. The game is using an updated DX11 version of the Dragon Ball Xenoverse [Street Fighter IV Engine (highly modified)]. Zyrusticae's bits give 100% most of the time but isn't perfectly scaling/syncing a-cross the two cards, cause a slight stuttering/frame pacing issue. Any help would be appreciated.

    Short of actually buying all of these games and testing them myself, I can't say anything for sure.
    But Dragon Ball Xenoverse 2 seems to be running on UE4, at least according to the PCGamingWiki.

    So I would suggest one of the more "critical" SLI bits.
    Essentially "0x080080F5", "0x080020F5", "0x080040F5" or "0x080010F5" would typically be good candidates.
    If that fails, you can also try out just "0x080000F5" or combine this profile with the "Unknown" SLI function "0x00A06746" set to a value of "0x00000020".
    Sometimes such aggressive profiles can break TAA though, so I would suggest testing with just native 3840x2160 resolution and FXAA to begin with.

    However on a completely general note, it really isn't very helpful when people just post random undocumented profiles from the Steam forums or other "suspect" sources.
    I suggest everybody reading this post instead have a look at a small SLI guide I wrote a while ago:
    General information on advanced SLI bits

    It isn't exactly complete yet, and needs to be updated in a few places.
    But it should explain the "basics" of using and testing more advanced SLI profiles.
    This "guide" can also be found linked under the SLI categories in my master list spreadsheet:
    NVIDIA compatibility bits master thread and IQ guide

    Many thanks for the suggestion.

    So,in single gpu mode i have 38-46 fps and 95-99 gpu usage(disabled AA via cfg and shadow on High,everything else on max).with the killing floor 2 bits its gives a rock solid 60fps(with AA and shadows on ultra) and gpu usage is between 75-85 on both gpu.i am going to try the bits you suggested and ill be back with the results.thank you

    so the 0x000000B5=bad performance and terrible flicker

    0x080000B5=the best so far,good scalling and no flickering,but there is some shimmer on some trees and shadows.

    maybe the SLI broadcast option and dx11 hacks option in the NV inspector can do something to solve this shimmering?

    Thank you for your help but it does seem as tho the bits that Zyrusticae over on Steam Discussions came up with work as well and better than these ones. It would seem that they used your guide, just added bits #20 and #29 to "0x080080F5" making it "0x281080F5" and giving about 20 to 30 fps more than the for menaced bits with the same or maybe better scaling. "0x080020F5", "0x080010F5" and "0x080000F5" with "Unknown" SLI function "0x00A06746" on cause flickering. "0x080040F5" works without flickering but bad syncing, "0x080000F5" by it's self works okay but "0x080080F5" works better with better scaling and syncing, but all in all "0x281080F5" still seems to give the best of both.

    @remicius

    Very interesting about the "0x080000B5" profile.
    This is essentially just the basic AFR2 profile "0x080000F5", with one SLI function disabled.
    What kind of "shimmering" are you talking about exactly?

    You could try and disable further SLI functions using the bit value editor in Inspector to attempt to solve this, i.e. 0x08000005.

    @Neorwin

    I'm not exactly sure what you mean by "syncing" to be honest, but perhaps you could provide some screenshot comparisons of the different profiles with FPS numbers.
    Only then might I be able to figure out exactly what kind of SLI functions are needed, and which are redundant.
    I suspect something like 0x081000F5 or 0x280000F5 might be sufficient.

    Ah OK, now I understand.
    This is what I would call "shaky vegetation".

    Normally the solution is to disable certain aggressive SLI functions, but with this engine it might be different though.
    Try 0x08000005, which is just basic AFR1 mode with only bit #27 enabled.
