It's better. There was only one patch that really had any problems and those were corrected in the one after. There are still plenty of glitches but significantly less than on release. If you happen to play on PS3 some patches helped a lot with performance too.
Either way though, as I said I'm on PS3. I don't even know if you guys can defrag. I bet you can though, and it's less of a process than we've got. =' (
Nope, no defragging for us. As it's a Microsoft product it could probably do with it too.
I do seem to get way more freezing than I did when the game first came out. Now that I think of it it has been worse since 1.9. I hate having to get up like 3 times in ten minutes (sometimes) to go manually turn off the Xbox because the entire system is froze.
Plus, I try to save a lot because of this, but sometimes you get deep into the game and you forget to save (and autosave hasn't kicked-in in a while either) and the game freezes and you just lost like an hour or more of either awesome play or a part of the game you really have no desire to play over right then and there.
Still, I mumble in frustration, live with it, and Skyrim on.
