It enables a GPU performance counter entry for developers to either use as an administrative access or for all users. It's a low-level access perfToolkit for debugging and identification primarily for developers. Vulnerabilities for it was addressed in the previous driver.
I don't believe that you can directly switch from Standard to DCH drivers. I used Wagnard's DDU to totally uninstall my old Nvidia driver and then was able to switch to the DCH version of driver 419.35. It was difficult finding the link to the Microsoft Store App version of the Nvidia Control Panel, but I finally found that as well. That Nvidia Control Panel app only works with the DCH driver.
I also put my PC in the Release Preview Insider Ring, but was not offered version 421.65 as of yet.
Apparently, 421.65 may help with performance issues caused by KB4482887.
