The hardware limitations on the console caused obvious instability in the game that I don't think they ever fully resolved.
Except they released the game, in "enhanced" version, on the Switch, which is just old android phone hardware from several years back. The PS3 was totally capable of running it. The port simply failed - time constraint, investor pressures...doesn't matter. They chose to not make it better in the end when the hardware was perfectly capable of running the game.
But I don't think most people played Skyrim on PS3 so they aren't going to have that same experience. I know I didn't.
The number of people that play a game on console is vastly underestimated by pc-primary gamers when previous titles by a developer were PC only. Skyrim on console was big. Big enough that they decided to port it to everything they could. You don't waste that kind of developer time and not expect a return...
