The original Xbox 360/PS3 game launched with a tidal wave of bugs, some of them game-ending.
One particular collection of technical gremlins trapped me on a farm during the prologue.
I saw a distant rider stop-starting through a canyon with his own hat darting through the air behind him.

I followed the man for as long as I could, before tumbling through the terrain into uncreated space.
I’m going to chalk this up as a “maybe”.
Rockstar’s approach to porting stuff to PC is, I think it’s fair to say, belated.
