    Any body had a bad performance hit with the latest Nvidia drivers. Last night my fps was terrible for the first time .The only thing Iv changed is the updated driver yesterday.No problem in the other sims.

    I had this effect after accidentally installing NVidia Experience and letting it optimise ACC. After that all was on low but I had half frame rate than before. Deleted it and restored old setting and all was back to normal.

    For me it was NE not driver or ACC fault.

    Ahh the wonderful world of PC gaming, you spend hours optimising stuff only for Nvidia/AMD/Microsoft/Whoever to update something and land you straight back at the star with a weird and unknown issue to work through

    I can confirm this....
    FPS is breaking down by 80-90% GPU Usage (RivaTuner OSD Info) on my system. Before the update i had most of the times smooth 60fps (vsync on and fps limit on monitor refresh time). Now i its going under 60 fps and gives me bad stuttering.

    will revert to previous version

    At first I thought that it seemed to me that fps sometimes stutters. And then I remembered that I also updated the nvidia drivers :)

    But this happens only with replays.

    Fair few people are having issues with latest Nvidia drivers it seems. The iRacing guys have also had some performance problems

    I have to change my feedback. I had no issues in practice mode, but in race mode (GPU load higher) I had stuttering. I reverted to previous driver and the stuttering is gone.

    I'm guessing you guys are about the 431.36 drivers, if so they are not coming with good reports over at Guru3d, and if you look here and over there the common dinominator is Win 10 that great bit of software..:p

    Well I have always kept my drivers up to date and obviously downloaded this newest one.
    Went to play ACC and my Oculus Rift wouldn't fire up and just had a black screen.
    I could still hear the sounds, but no picture at all.
    I tried just the Rift itself, in Oculus Home and no change at all, just a blank screen.
    Tried unplugging it and putting it back in and trying different USB ports, but nothing worked.
    I even tried resetting up my Rift as if it was a new one, but again, just a blank screen.
    In OH (on the desktop) it shows in devices that its working fine.

    I have now uninstalled the newest nvidia driver and rolling back tot he previous ones.

    I must admit immediately after the upgrade things didn't look right straight away, but I then discovered my system needed a .Net patch (I'm on Windows 1903) and bios too needed an upgrade, including the ME and microcode... long story short it now works same as before for me.
    Maybe try a clean install instead of an express upgrade if that's what you did.

    Except for using it only for installing new drivers. Easy peasy. ;)

    I believe need to return to the previous version. As always, updating the video driver is a lottery. And usually losing)
