just chiming in an saying geforce now is pretty amazing. i'm using it on my steam deck and the performance over playing it natively on the deck is so much better. constant 60 fps, higher resolution and max settings. my internet dl speed is about 330 mbps and i haven't had any issues, doesn't even feel like it's streaming.
i do have the ps5 version preordered. larian has done such a good job with the controller ui that it's my preferred way to play the game.
I would buy a copy on ps5 if we could do custom parties. I have to use a mod/workaround to get the party I want. I could suffer through the other unmoddable things, but custom party is kind of core for me.
