YouTube already does that, though? In fact your premium sub helps creators much more than a non-premium viewer does. Of course the multiplier proposition would be new/different.
Not trying to shill for YouTube but that’s one of the main reasons I have a subscription is to support creators I like.
I would agree with this, I use Nvidia cards for professional work on Linux and I’ve never had a problem. Yeah there’s some upfront work configuring the drivers, but I’ve never had it take more than an hour to setup.
