I think you misunderstood the commenter you replied to. The issue is he’s blaming Thor as if Thor singlehandedly killed the initiative, when in reality it’s a wider societal issue.

Not really. Default drivers should work just fine. If you want to make sure they’re installed and running, run the following in a terminal:

glxinfo | grep Mesa

If you have any output, you have Mesa. It’ll tell you what version you have as well.
