"Thank fuck for the first one.

thank god for the performance fix

Yay, Cowboy Repeater fixed.  I always wondered why sometimes my mouse wasn't responding so I thought I needed a new one.

When they say "performance fixes", do they mean what I think (read: hope) they mean? No need for the DLL fix anymore?

 Watch out. Apparently after the patch a lot of people are having issues where random enemies can not be killed (they only become unconscious).

EDIT: Looks like they just pushed out a hotfix to fix that.

" @FritzDude: I meant the companion waypoints. I've lost Boone altogether :( "

" When they say "performance fixes", do they mean what I think (read: hope) they mean? No need for the DLL fix anymore? "

So the dropbox/deliver items thing is how they are going to do the DLC? Could be good. 
 
These changes dont really effect me that much though I never encountered many bugs or any game breaking bugs.

I've played around a bit with the latest patch/hotfix installed and I must admit the game is running more smoothly than with the D3D dll fix. Even if some people are complaining about their games being broken by these updates, everything's more than perfect for me. I can hardly wait for the "proper" patch to be released in the next few days.

Game still runs choppy for me even with new patch, so gonna be sticking with the .dll fix.

I guess the White Glove Society crash is getting fixed in the next one. Sucks for console players trying to help out Yes Man.
