I am sure it allows the best environment for installing a new driver and I think this could be part of the reason my performance is so good allowing a ‘squeaky clean install without older driver files causing problems’.It is often recommended to disable networking or turn off windows updates to prevent Windows from installing the driver itself. I have never had a problem caused by this little software program. If your not using the DDU tool and are experiencing poorer than expected performance, you can try the driver uninstaller at your own risk. Always make sure you don’t allow Windows to download what drivers it believes are best, it always rolls back to an older WHQL driver which is not always what you want. Make sure Windows does not roll back to an old driver behind your, ‘back’ This has happened to me several times and the old driver never gets removed properly.

I am using the DDU tool remove all traces of my old driver along with the registry entries and then selecting custom install and ‘Clean Install’. This is the second time a new Nvidia driver has caused the same problem with my monitor display. I had increased stuttering with the new driver too. The biggest downfall for me with the new driver, I could not get my monitor to initialise with a DVI cable without turning the monitor off and then back on. I can see a significant gain in FPS reverting back to the-hotfix driver and I can push my ‘Super Sampling’ to 6X which was not possible with the new driver. I have spent hours testing this afternoon. On my system with an MSI 1070 over clocked and with an overclocked CPU using the same Windows and MSFS settings, THE NEW DRIVER UNEQUIVOCALLY KILLS MY PERFORMANCE. HERE IS MY CONCLUSION with regard to the new WHQL driver from Nvidia, (458.38). I have photogrammetry turned ON and have live traffic enabled.
