ok so:
if you really want the older drivers make sure that the old version of your nvidia drivers are still in the pacman cache located at /var/cache/pacman/pkg
I for myself installed them manually with the dkms package so for me my pacman line is
sudo pacman -U /var/cache/pacman/pkg/nvidia-dkms-460.73.01-1-x86_64.pkg.tar.zst /var/cache/pacman/pkg/nvidia-utils-460.73.01-1-x86_64.pkg.tar.zst /var/cache/pacman/pkg/lib32-nvidia-utils-460.73.01-1-x86_64.pkg.tar.zst
460.73 was the latest working version for me
phil linked the blog post where a link to the old drivers are, if you dont find them in your cache you can still download them from there and use the same command like me just with a different location. Then you can reboot to try if it worked for you.
After reboot you need to edit your pacman.conf or else you will just update again with the 460.80 packages that broke everything. For that do sudo vim /etc/pacman.conf (or use nano, your choice, I am used to vim). Look for the line that says IgnorePkg, uncomment and type in the names of the packages you just downgraded, for me the line would be IgnorePkg = nvidia-dkms nvidia-utils lib32-nvidia-utils after editing. You can confirm that your edit did its job by opening pamac and and looking at the updates tab, it should show the downgraded packages but shouldn’t offer you to upgrade them.
This should fix it until Nvidia did their f***ing job.
