I remember I was on the PC an hour before it's release after I pre ordered and I was waiting like crazy for it to release, I played it exactly when it got released on Steam, and to be honest, never witnessed any bugs on the first day of the game, and I finished it all. The only bugs I've encountered was trees overriding the view but it was due to Nvidia driver that wasn't updated. And a side quest that I can't finish for some reason. Other than that I never witnessed any bugs at all, never understood why people complaining about it when I played it since day one
I reckon PC was way more bug-free than the consoles cause I the only bugs I had were charming and hilarious ones, like my car spawing vertical halfway through the floor or enemies dying with their eyes open and still talking shit hahaha I was tripping because I remember when Skyrim, Fallout 3 or the original Red Dead came out and they were fully broken to the point of being unplayable, yet there wasn't a big drama about that.
