The complaints aren't about CP77 performance on Xbox Series X or PS5. They're about it's performance on non-X Xbox One and non-Pro PS4s. Which aren't just last-gen consoles, they're the lowest tier of last gen consoles. I don't think CDPR should have released the games on those platforms if they don't have their performance scaling right. I'm not defending their actions, but I think most people just have their expectations out of whack.
CP77 is the first AAA game released in a long time that was built for PC first and ported to consoles, instead of the other way around. Instead of PCs getting crappy ports hard-limited to 60fps no matter how much GPU you throw at it, and crappy control schemes, the dregs of last-gen consoles got really poor performance and visuals compared to people on PS4 Pros, Xbox One X, and the latest 2020 gen consoles. It's not acceptable, but it's also hard to imagine how you could have made people happy when they're that far underpowered from a hardware department for a game like CP77.
