Ok I'm at the end of my rope with single digit fps in way to many areas Judging by the lack of response of any kind from the makers of this here beta I am not holding my breath for a patch anytime soon. I've got the 260.99 driver, I've disabled all the settings that are the reason we buy pc games and not console versions. So what is left? I dam sure will not be offered q refund.

So my question is is this dll file safe? Can it hurt my hardware? Does it alter anything else besides this beta? Will it give 'me the fps I deserve or just fix the npc bug? I'm paranoid when it comes to my pc. Help quell my fears before I throw this beta that I was conned into paying retail for in the garbage and loadup up fallout 2.

Didn't get any framerate issues, but I tried it yesterday in hope of fixing the random desktop crashes. For a brief moment it raised my hopes but they were dashed quite expertly. Still crashing every 15~30 minutes or so, I stopped playing for now.

It's safe if you get it from Nexus. The Megauploads version had ads on the download page that infected people. It was not the dll file itself!!!

Just try it, you may be rather pleased with the results. I sure was! (I'm running dual 5870s and still need to use it.)

I got it from the nexus and my system is fine. It really did improve the framerate.

Something else you can do if crashes persist, that I read on this forum is: turn off FNV's AA and AF, and then if you actually want to run those settings force them with your video card settings.

People have said here that helped stop the random crashes.

The d3d9.dll does not alter any files. The only way for your hardware to permanently take damage would be if your computer short circuit or overheats and hardware have safety specifications for that.

The dll file only tricks the game into thinking that your using a graphic card that only supports dx9 so the game wont try and load the more advanced features. Once you delete the dll everything will return to how it was.

This may be a stupid question but can't you run games in, say, windows xp compatibility mode? Does this do anything for fonv? Why would that not do the same thing as the dll file? For posterity my specs are as follows:

Win7 64
Wolfdale 3 ghz dual core
Gtx 280
4 gigs mushkin high perf
Evga 790 mobo

Yeah I wish it could be fixed by simply using a compatible mode such as xp sp3, unfortanetly there is no change betwean win7 and a compatible mode when it comes to fps improvements. I can't answer your question as to why the FaceGen software isn't loaded in a more efficiant way while using compatible mode.

I believe there is more then one version of the dll around. The one I got from nexus does not list my card as a 7900, but instead shows my actual gtx 260. As far as not loading advanced features, I cannot tell the difference visually at all, just that my frame rates went from teens and 20s around npcs to a constant 60 and no stutter. Using latest nvidia driver and d3doverider...

The dll fix was the only thing that would work for me. it reads as a 7900 (i have a 260). I got the file from nexus as well. If it wasn't for that I'd still be raising hell, but being able to finally play the game distracts me from doing so.

It's reasons like this that I use Ad Blocker Plus. I was one of those that got it from that site but fortunately was not infected thanks to ABP as well as No Script. Looks like they have saved me a ton of trouble.

Speaking on the Nvidia side (250 GTS 1 GB) there is nothing wrong with the .dll (7900). Only thing that keeps me from throwing this Fallout New Vegas beta in the trash.

I checked it with Zone Alarm, Malwarebytes Anti-malware, and Windows Defender. All give it a OK. If you are that worried, you can always pull the .dll from your Operating system, although you get better result if you download the tweaked version.

I hear there is also a version for ATI cards as well.

And a side note to Chris Avellone, I find your lame excuses lacking. Many of the bugs were/are quite obvious. Quality Assurance Anyone?

Chris, would you care to pre-order some swamp land in florida?

I also use both and was not affected either.

Would have been my first virus/trojan, ever. *knocks on wood*

Regarding the crashes, if you have a quad core processor, search the forums for the fallout.ini fix for that issue. I had pretty regular crashes in Fallout NV and Fallout 3 prior to making the changes in the INI file, only a couple since the changes.

Regarding the d3d9.dll, is this simply the d3d9.dll from a Windows XP machine?

I have an Nvidia 8800GT and the .dll fix worked really well for me. I almost want to start the game over just so I can enjoy it lag free, but I'm so far along I'll probably just finish and make a new character.

I plan to remove the dll whenever a real patch comes forth, but until then I'm using it. I got sick of laggy gameplay around every single NPC and I'm so glad I decided to finally try it out.

It shouldn't hurt your hardware, but I'm not going to buy you replacements if it does as I'll be too busy replacing my own . If it doesn't work for you, just delete the file. A dll is usually just a big library of functions, but in this case I think it's a big list of functions that do nothing more than pass their data on to different DirectX functions that avoid the cause of the slow-down (whatever that turns out to be). Of course I could be wrong and Cthulu might come eat us all. For his convenience, I will be parked next to my PC playing FO:NV.

I have an Nvidia 260 GTX as well and also have horrible lag. I'm not inclined to try a dll from a download site. I have emailed the d3d9.dll file (zipped to get through the filters) from my work Windows XP system to try on my Windows 7 rig.

I'll try it tonight and report whether it makes any difference. If it does work, this will be an option for folks who don't want to download dlls from random download sites. If it doesn't, crud!

I have a 480 GTX and the DLL patch fixed my fps slowdowns.

You're going to throw your video card in the trash? Well I suppose that's something. You could always give it to me, I'd be fine with that too.

The slowdown/etc problems are generally related to the drivers released by nvidia and ati. ATI has already released a hotfix, listed elsewhere(or hit a gaming site to get it). Nvidia hasn't released a fix yet. The DLL files themselves(ATI and Nvidia versions) force the game to ignore certain features which the drivers themselves are not rendering properly.

Somebody's a Futurama fan I see...

In reference to using files from other sites, there is a web based multi-AV-scanner @ http://virusscan.jotti.org/en - I have used it many a time for suspect files/sites and It is fairly comprehensive.

I will also second the above mentioned noscript addon for firefox. I was a wonderful cherry to top off my layered defensive system.

./endthreadhijack

I wouldn't even consider surfing the net without noscript. It is impossible NOT to end up with some malware if you just run every piece of code.

The DLL is unfortunately the only good fix for most people. What surprises me is this whole "it's the drivers fault"... well if it is, what other games have similar issues. NV is not so cutting edge it's using some feature that no other game is. Given all the other issues it's probably an implementation issue with NV.

Can I get a link to the d3d9.dll download please? The nexus file seems to be missing.

It just worked fine for me when I tested it.

http://www.newvegasnexus.com/downloads/file.php?id=34778

how would i go about doing this?

In the world of drivers, software doesn't have to be cutting edge to cause problems with it.

For example, bad implementation of the dx overlay can cause black screens in XP for games that only need DX7/8 to run. Another fine example would have been the WoW problem back when Orgi'la came out in burning crusade. For 66xx/7xxx series nVidia owners, their cars dropped to a crawl. It was a two fold problem. First the drivers were ordering improper linear executions of the terrain, the second was due to the way the land was created causing 'under render' issues. Effectively the cards were rendering terrain, under terrain, instead of the simple surface terrain.



Go into CCC(catalyst control center), or whatever nvidia calls theirs now. Look for the AA/AF settings under advanced 3d options. There should be a checkbox or something similar that says 'let the application control these settings'. Uncheck it, then set 2xAA 4xAF or whatever you want. Save/exit/apply whatever. Then go enjoy the game.

DLL fix in place and the game is running smooth at 60 fps(synced with my monitor) and rarely a stutter on ultra high. For those that have been saying that a relatively loud tiny minority of [censored]y people have been having issues with this beta, plz explain why the dll fix has over 100000 downloads.
