To be fair, I haven’t played 2077 on launch day but like 3 months later, on a medium-high gaming laptop. I‘ve had zero crashes, no T-poses and generally nearly no bugs.
The real problem was them releasing the game on last gen consoles which were (like low tier pcs) unable to handle the game. I would even go as far as to say that they made a game that was only playable on high tier hardware.
And interestingly enough now 2.5 yrs after release, the game has more bugs for me than it had 3 months in.
I‘m not a game dev so I can’t say why that is but as a dev I can say that fixing one bug might introduce another which becomes a lot harder to fix.
