    Hi Folks

    I'm experiencing lag/stutter when moving windows or scrolling up/down AFTER playing a game. It's only happening with the HB Bridge or 2 soft bridges installed. If there is only 1 soft bridge the problem does not occur. GTX 1080 2-way SLI. Windows 10 64 1607 anniversary update.

    There is a 5 page thread on the issue at the nvidia forums, I'm just posting here to see if anyone is experiencing the same issue or knows a solution.

    Thanks very much

    Well, I also use an 80 mm NVIDIA HB bridge with my Zotac 980 Ti's:
    https://www.caseking.de/en/nvidia-geforce-gtx-hb-sli-bridge-2-way-80-mm-gcnv-003.html

    And I don't experience any of these issues, so perhaps this is a Pascal driver bug?
    Running the latest Windows 10 Anniversary build 1607 BTW.

    Are you guys sure this is not some new background application in Windows or in the NVIDIA drivers causing the issue?
    I always recommend only installing the GPU drivers and PhysX software from the driver package, nothing else.

    Out of interest, does the HB bridge make a diff to the 980Tis? Have you benchmarked different bridges?

    I have, but only Blaire made some posts about it on the 3DCenter SLI thread.
    The basic conclusion is, that with older drivers (e.g. 365.xx and older), the HB bridge does give some additional performance in very bandwidth limited situations with Maxwell cards compared to a flexible SLI bridge.
    For example with native 4K resolution combined with temporal AA in some games.
    (Not to be confused with 4xDSR at 1080P resolution)

    But with 368.xx and newer, this changes due to changes in "frame time behavior".
    However in many cases the "pre" 368.xx behavior can be restored with custom SLI profiles.
    Fallout 4 and Witcher 3 with native 4K and temporal AA are good examples:

    But honestly I mostly got this bridge because it looks nice in my case, and to prepare for future cards really.
