Jedi survivor on ps5 pro

So I've bought a ps5 pro, my first playstation since the ps1, and first console in over 10 years. I only play the odd game on PC (single player) but find I don't like sitting at my desk to do so.

I finished Fallen order which I loved and have waited for this console to play the sequel. I'm now reading lots of comments about how it's unplayable on the ps5 pro and seriously considering not bothering to unbox it tomorrow if that's the case.

I've only got the one game so I'm a bit miffed that I won't have anything to play.

Is it as bad as people say and can settings be changed to fix it?

Thanks
