Nvidia cards are supported with the proprietary drivers; the game I play (Stepmania, OutFox) historically was without artifacts on nvidia systems. Nowadays, Wayland is moving forward, and nvidia is just behind on supporting it compared to AMD. According to this thread below you should be fine as long as you use nvidia drivers from version 560+.

Doctors are not individual practitioners and cannot normally decide to go off on their own doing a procedure that they were not specifically trained to do (doctors are trained in procedures during their residency and in CTE). Unless they are offered a course in this new method, the hospital would not authorize them to perform that new procedure. The best way to get this care would be to travel or to lobby the hospital to train staff on this new methodology.
