From my experience, this was a pretty lousy port. Walking and combat was fine, but whenever I got into the vehicle the game just seemed to stutter, which is a pretty big problem for a sandbox game. Couldn't even get rid of this issue when I lowered the settings to the bare minimum. May just have been something on my end, but I know there's been a lot of complaints about the PC version. Damn shame too, incredibly fun game on the consoles.
