    Hi, I recently encounter an issue with using graphics api dx12 for all my unity editor versions on windows 11, does anyone know why?
    As long as I switch to dx12, all the windows in Unity editor just go black and shining, see picture below

    Graphics card: Nvidia geforce RTX2070 Super
    Graphics driver: latest 526.98
    Windows 11 version: 22H2 (Just updated today, but previous versions failed on dx12 too)

    Tried to udpate & switch several graphics driver, and also updating windows for the past weeks, does not solve the problem. I have a few projects that is dependent on dx12 ray tracking, can't use them any more now.

    Hi, yeah I did a clean remove on all the nvidia related drivers and reinstalled them all using DDU (Display Drivers Uninstaller), then it worked.

    Thanks, this lead me to dig deeper, and discovered the issue is with MFAA. To anyone who finds this post later, disable MFAA if you enabled it (it's usually off by default) in your NVIDIA control panel.

    This same issue also happens with Unreal Editor, so people may find this solution that way too. Adding this line for google keywords lol.
