It is just unfortunate that it does not run on Nvidia hardware. The benchmark runs if you disable all RTX features, but it crashes on a new game before you even have full control of the character.
Looking at protondb it looks like all people with Nvidia have issues since the 2.0 update. I hope there will be some fix soon. I don't want to replace the GPU yet it would be a waste (2080 Super).
For now I am playing it on my Steam Deck instead.
Emphasis on it was. It started to go downhill with Amazon integration and now we have paid security updates. They are holding back developed and available security packages for their OS!
There is no way to still recommend Ubuntu. No need to even talk about the other questionable decisions like snap.
