Install this program, NVcleanstall to install Nvidia drivers. It cleans out any remnants of old drivers and then installs the new drivers. It's easy to use and works very well, I used it a couple of days ago and it improved the performance of my 3080 card with more fps and removed the odd stutter I was getting. https://www.techpowerup.com/download/techpowerup-nvcleanstall/
I've never used DDU but I have investigated it. NVcleanstall isn't so comprehensive but is lot easier to use and probably more suited to people who are not so computer literate. DDU could possibly cause problems for some people. I've always used the clean install option with the normal Nvidia installer until I used NVcleanstall.
Guys there is an order to follow 1.DDU in safe mode to completely uninstall drivers 2.NVclean to create an installation without the bloat i ll send you a video its the one or the other you must use both
NVinstall video method i recommend use his method A F T E R you use DDU in safe mode and ofcourse you MUST NOT be conected to intenret because new GPU driver will be install automatically from Windows update
You can stay connected to the net, there is a setting to stop windows updates for X days(at least for Win 10 & 11)
