i feel aweful there are still people unable to play this much aticipated game. I have a fix that might work for a lot of you it definately worked for me! To give you something to relate to, i have a gtx 480 and was having that stuttering mess of a problem, the game was unplayable. the dll fix made it a tiny bit better, but then the new nvidia drivers made it horrible again. Now i am playing new vegas damn near absolutely perfect! perfect framerate, perfect everything. I used the fallout new vegas 4G file at newvegusnexus.com. YOU NEED TO USE THIS FILE ALONG WITH THE DLL FIX, go to

http://newvegasnexus.com/downloads/file.php?id=35262

(you will have to copy and paste it i dont know how to make it a link) and read the description so you can understand what you are downloading and how to use it (its very easy) and then click on the files tab and download the "Binary and Source Update 2". i think many of you will be very happy and relieved. after a week and a half of agony over not being able to play my brand new new vegas game, this new vegas 4g file has kind of been my video game savior lol as i have been playing new vegas for 25 hours now with now stutters or eff ups. and yes the wasteland is beautiful. so grab those special nugs yall have been saving, its time to get down on some new vegas.

This is designed to be used by players with 64 Bit Versions of Windows. Usage on 32 bit Windows is unlikely to work (will run but wont incress the address space).

yes this is a true true important statement that i forgot to mention, thank you pattex96 my b niggy

overall ram usage (win7 x64 AND new vegas together) was only 2 (!!) GB, this game does not need much ram, i cant see the point of a laa fix.

have you tried to set water multisampling on low?
this is a must with nvidia cards.
