We currently require 460.32.03, however the 460 driver series got succeeded by 470 LTS one, which supports the same hardware. Thus all users can (and should) already have updated to 470.82. Distros like Ubuntu appear to ship the latest drivers as security updates to all supported versions.

Bumping the requirement to 470.82 has the great advantage of being in sync with the required version for EGL, i.e. all Nvidia users with HW-WR will use EGL by default (minus bugs like bug 1739611). This solves a couple of Nvidia+GLX related bugs at the price of downgrading some users with outdated/unsupported drivers to SW-WR. For these users, SW-WR likely gives a more stable experience anyway. If they want the performance benefits of HW-WR, all they need to do is to update their drivers (again, something they should do anyway for security reasons).
