I’ve been using the GPU accelerated RC suite in PixInsight on Linux for a couple of years now. The process is practically the same - remove the tensorflow libraries that PI installs and you’re good to go!
I don’t remember how long they took on the CPU alone (Ryzen 5950X), but it’s basically breathe in and out a couple of times and it’s done on my 4090. Happy days
What other PI features are reportedly enabled on the 50x0 cards?
