Nvidia drivers 418.91 Caution

  1. Great to hear. I have it installed but haven't had a chance to take it for a spin yet in ACC. Might as well wait for the next drop at this point.

    Never done that and never had a issue.

    I never update without DDU ;) but it's possibly not needed

    Why wouldn't you click 'clean install'?
    It may work fine not doing this, but surely uninstalling older drivers before putting new ones on is bound to be better for your system.
    After all, its only a click of one button and doesn't take any longer.

    Why not just run DDU , it only takes maybe 2 minutes more and your guaranteed a clean install .

    I have used DDU for many years and will use it if I run into issues.

    I export all my profiles into one *.nip file via Nvidia Inspector, disable windows updates temporarily and always perform a clean install. Then you can import your profiles once the new driver is installed.

    This is also what I plan to do if I experience problems.

    I have always been really paranoid about these things (clean installs and whatnot). But the thing is, since moving to Win10 my computer has been really stable, and a couple of years ago I started to just install new drivers via Geforce Experience. It's the simplest thing in the world. Just clickety-click and done.
    I haven't had one single problem since I started doing it this way. And until I experience a problem I will just continue to do so. Because why not. :)

    @Whitestar - Personally I am not a fan of Geforce Experience. I tried it once a while back and it caused all sorts of performance issues for me. I think it was auto-tuning etc.. I also didn't like how nVidia were forcing users to install this with their drivers. To be be fair it may have changed alot since then however for me the less nVidia processes running in the background the better + I prefer full control that's why I like Nvidia Inspector. I also don't have alot of games so tuning for me is fun :)

    That's why I recommended the driver and Physx only to be installed.
    The least the better.

    Fully agree, and I would never use it for any kind of performance tuning, I use Inspector same as you.
    The only thing I use it for is installing the drivers, and occasionally desktop recording.

  13. Hi,

    A little bit off topic but, I just would like to know if Nvidia Inspectors users use it to optimize Antialiasing and Texture Filtering for ACC and what settings used.

    I always click ‘clean install’ and always select everything (although I don’t need any 3D stuff) and never had an issue.
    Only thing that has ever caused any problem was not having the DisplayPort cable in the 1st port. My chosen Nvidia colour settings would always revert back to look washed out when in port 2. Quick switch fixed that.

    I did enhance AA for a while in AC however not with ACC. I'm not sure its even possible with ACC as it maybe disabled. Depending on your hardware you can try different combos. ie. 8xQ + 8x Sparse Grid. I do not enhance or overide anymore. I found my sweet spot. I believe AC uses MSAA therefore I enable MFAA in nV Inspector. For AC I also edit the the user video.ini file to include the following:-


    For ACC I have edited the user UE4 engie.ini file to include the following:-


    I used to do alot more in the engine.ini as TAA is so blurry however since Kunos added the sharpening filter most of that code can be dropped.

    As for textural filtering... I turn off Aniostropic filter & sample optimization as well as Trilinear Optimization. I always set texture quality to High as my 1080ti can handle this fine. One thing I always switch on is threaded optimization. One thing you may wish to play around with is line gamma.

    Now my turn to go a little off topic. For all DSR users. After I install new drivers I prefer to create custom resolutions that are true 16:9. Such as 2304 x 1296, 2560 x 1440, 2816 x 1584, 3200 x 1800, 3584 x 2016 & 3840 x 2160. This can be done easily through nV control panel. I never enable or use DSR as the factors (1x, 1.25x..) gave me weird resolutions that were not true 16:9. The array of resolutions I create caters for a wide range of games and their performance demands.

    I hope this helps a little
