What is the point of DDU?

[remo233]

If you select the clean install option when installing nvidia driver, is it not the same as DDU?

Nope, Nvidia's clean install option does not remove every single trace of the graphics driver on the system like DDU does. Nvidia's clean install just removes user settings and previous driver versions, DDU fully cleans out the directories, system folders, and registry.

DDU is almost never needed, though.

DDU is something you do when you're experiencing issues otherwise unexplainable. I've never really needed it but I've seen it be helpful for very strange problems or performance issues.

actually when upgraded from my gt 710 to 1050 ti, all games were crashing with a beep sound on startup. IIRC i did a clean install of the drivers but didn't fix it, we checked the gpu in other pc and it was fine so after that i used ddu and my problem was fixed.

Hence the concession "almost never". Although rarely needed, it can be useful.
