thank fucking god someone came out with this already.  i was already sick of the fps and i loved how smooth f3 ran on my comp

What? The description is terrible, what does it do and what is it for?

My (legit retail) copy showed up a couple days early and I can't play it because it's not supposed to be released in the UK until Friday, so Steam have taken it upon themselves to lock me out of my game until then.  Is there a patch for that, or do Valve just need to go fuck themselves?

Thanks! I'm hoping they will release something similar to the Fallout 3 thing which made it possible to use +2gb ram soon.

Damn, that works great!
 
My comp:
Q6600
9600GT
2GB RAM
 
FPS without that file on High Settings:
The Strip: 30-40
Gomorrah Casino: 20-35
 
With the file:
The Strip: 60
Gomorrah Casino: 50-60
 
Still a bit of slowdown at times, but it disappears pretty fast.
 
EDIT: On Ultra, I only lose about 10 FPS. That is one awesome file.

Nice. Il have to download it when I get it on friday. 

Looks good, ill give it a try.

Wow you are thick.  Just goes to show how rushed this thing was. "

Wow this topic is getting hostile here is a pallet cleanser  
    
Nice download man, thanks for the link.

Just started up Steam and an update is downloading. Might have fixed this problem already.

I'll give this a try, but after seeing if the patched did anything to help first.

I actually got a lot better performance after tweaking the graphics setting by selecting "Options" in the launcher window (before the game goes full screen).  The auto-detect feature in F:NV set my game to Ultra-High graphic settings.  I could anticipate every crash because it was preceded by a huge drop in frame rate as my machine choked trying to render too much detail.  By going into "Options" in the launcher window, I simply changed the general graphics settings from Ultra-High to High (you can do more tweaking if you want in "Advanced" settings).  I'm getting a much better frame rate and the games crashes a lot less.  I know it sounds pathetic to toil over a game just to make it "crash a lot less", but I love Fallout!!!

Looks like I can't use it because i've got two monitors.
 
YellowOverdrive is right. If you graphics card is shitting itself, tone down the antialiasing and draw distances and LOD sliders. Just a few notches lower on some of the more useless features like grass improved my framerate a lot.

Yeah this tweak helps alot, apparently the graphics card wasn't being utilitized when there would be NPC's on screen and it was causing me massive stuttering.  You just drag the direct x 9 dll file in the fallout directory and it seems to alleviate all the rendering performance issues.

This is good to know.  I'll go install it once I get home.  I was having a lot of choking framerate when an NPC was anywhere in my screen.

Real real sad the game devs could not do this. The game is barely out and someone has fixed it up all ready. 

Installed and played last night. This finally made my game playable. Thanks!

I just finished the game.... was not going to play it again even though i wanted to because the bugs were ruining it.  But this... i just tried it and it works REALLY well.  The Strip is no longer 8 frames a second.  Thanks for posting the link.  You may have saved New Vegas.

worth a shot

WTF is this black magic? When from 20-30 fps on medium to 50+ on high.
@kishan6: Thank you
