Hey, I'm one of the guys playing patched vanilla
Tried a GW mod sometime back & the game ran so slooooow.. Ended up having to delete everything & reinstalling the game & the 1.4B patch.. Miss the eye candy, but really enjoy playing the game at a decent speed & no CTD's.. Running the system on a 2.8 GHZ w/ 1 gig of ram & middle of the road video card w/ updated drivers..
Good Hunting!!
