If you're playing on a PC or console powerful enough, it's now just mostly Skyrim level visual bugs and stuff; nothing catastrophic. But they did not add in everything they promised, like for example the police system is as crappy as ever(but they said they are fixing that for 1.7). IMO, when the game is good, it's really good, but when it's not, it just feels disappointing since it could have been so much better. Mods can alleviate some of this though.
