I'm really enjoying the dlc, but a consistent lag and really bad loading times for textures offset me a bit.

The solution seems to be to delete the game from the harddrive and run the game from the disc, this bumped up the performerance quite a bit.

Has anyone else had similar experiences?

I had this problem for a bit but after awhile it cleared itself up.

Maybe it's unrelated to the disc install then. I felt it was relly bad (Ps3 type lag) when I first got there, but after I deleted the game and loaded back up it was a lot better.

I had lots of lag and freezing until I put about ten or so hours into the dlc then it just ceased to be.

For the lag, it's the netches. Kill them and it'll stop. I don't know why but it does. I had bad lag when exploring near them but killed them and it stopped.

That's because of the extremely taxing netch-generation technology they had to use when they created them..

It's their flight animations. Dunno why.

Noooo! Shh, don't talk about bugs or else Bethesda might delay the PC & PS3 versions!

Just kidding. Just hope this is a minor bug, easily corrected by a patch.
