Yeah, maybe he didn't grab it from the link. I scanned it too and there are no problems.

Well after the flood of positive reports I decided to break protocol and try this fix.

Bottom line. It worked.

In the basemant of Gomorrah Casino there is a dance floor. Before applying the fix listed by the OP
my frame rate was 15fps (fraps) if viewing from the floor facing the male dancer on one end and the females on the other side of the room.

With this fix a solid 60 SIXTY FPS even if the dancers boobs jiggle (maybe I'm seeing things).

What the F is wrong with you at bethesda? You release a game like this and blow HOW MANY sales due to some idiot oversight ?

ANyway, thanks for the fix.

Oddly, when comparing the filesize of the d3d9.dll found on megaupload and the ones installed in myi Win 7 64 bit system one notes a glaring difference that may explain SOMETHING.

megaupload dll size is a mere 104 KB
The d3d9.dll from the windows/sys64wow dir is about 1.74 MegaBytes or so (as I recall )
THe d3d9.dll from the windows/system dir is about 2.3 MB or so

The above figures are approx I' had looked earlier but didn't write the figures down.

Could it be MS BS bloat , just wondering.

I had tried both of the system dll's before trying the one found on Megaupload as listed by the OP but those did not work.
Using the syswow64 dll breaks fraps too.

As others have said, once I used the megaupload dll the game re-detected my vid and set my settings to medium. I set them to High as I had set earlier.
After I close this post I plan to restart the game using ultra since it seems to be running 1000 percent better around multiple NPC's.

For record system specs:

No, I used the link in the thread. If it's a newly minted DLL, no virus scanner is going to find it, since it'll be a new signature (as of today, or yesterday, or whenever it was created).

It's possible it's a total coincidence and I somehow got a slew of trjoans installed (including hotfix.exe, etc) at the exact moment I ran fallout new vegas with this dll... but I doubt it.

Dude, most games being released right now are still DX9 titles. DX10 doesn't really add a whole lot to most games visually, and DX11 is brand new. There isn't a huge incentive for devs to support anything over DX9 in their games yet...especially since a lot of people still aren't running hardware that can run DX10+ stuff at decent framerates, and a lot of people still game on Windows XP. You're not being ripped off. What, exactly, from DX10 would you like to see implemented in the game?

Also scanned this thing in all directions (came up clean), though technically that doesn't prove it doesn't have malicious code (ie, virus scanners only detect virus patterns they know). It seems absurd that someone would produce a fix for this issue only to load it up with custom malware though.

Well can we get some posts that ppls systems aren't all screwed up after copying this dll into their game?

I can confirm this works by placing the *.dll in the game's main directory under steam. "\program files\Steam\steamapps\common\fallout new vegas"
As mentioned earlier the video detection in the launcher will auto-detect medium quality but you can change settings to ultra and the game will run smooth.

If he had visited the original site where the file was originally posted with other Fallout New Vegas fixes he may have got it there, it had a LOT of questionable popups. I don't think there is any issue with the .dll - he/she's the only one to post about it. As far as the version of the d3d9.dll file is concerned, I'm going to try my file from work off of a 32-bit windows xp sp3 system updated to the latest available DirectX 9. File runs about 1.6 meg, then I will try the other one on my 64-bit Windows 7 system and see which one works best. Ultimately if neither work it's back to the one from the original post.

Frankly a working piece of software that does something useful is probably the single best baseline deployment vehicle for a piece of malware. Noone's going to run INSTALLROOTKITHAHA.exe, but plenty of people will happily drop in a dll that actually fixes an issue, or plays a cute video, or shows them the weather, etc. Alot of malware is deployed by perfectly reasonable and useful software and small utilities, so don't think that just because it's useful it's not doing something naughty.

Your mileage may vary, just reporting my experience. It DID fix my framerate issues...

If I had to guess you're looking at a shim/thunking dll that thunks to the primary directx dll, replacing just a few calls, telling the program that the video card is worse than it actually is, forcing some sort of directx 9 only code path. Who knows, it's certainly not a whole directx dll. It'd be easy as cake to take a legit working thunking dll and slip in some malware install code and call it a day.

0 problems on this end. I've had it installed for a couple hours now.

Yeah, you're quite right actually. I meant it in more of a uh.. in a fair and just world, solutions to really annoying problems wouldn't be loaded with malicious code. Because that would just be too horrible. ;D

Anyway, I'm going to continue using it for now. I just played for about 10 minutes and then ran a full system virus scan, so far all is well. Someone above mentioned that the site the OP linked to (the original place this was posted) was filled with bad advertisemants, and I wouldn't be shocked if the poster who reported getting slammed by trojans picked them up there.

It's still entirely possible that the DLL does include some backdoor which might only be used selectively by its author (ie, he has only used it on a few systems to test it), so I'll be keeping a careful watch on my system. For anyone out there who isn't familiar with dealing with viruses and general system catastrophe, I don't recommend trying any file like this until it's had a chance to be fully tested by those of us willing to take the risk.

Interestingly enough, the file on Megauploads is listed as "Fallout 3 fix," so I'm wondering if this is something that's actually been around for a while and just happens to work, or if someone simply mislabeled the upload.

I had this issue when I tried to turn compatibility mode on for FalloutNV.exe, the launcher would just cycle over and over. If you have XP compat. set on either the game or launcher EXE, try turning it off. Also, try launching the game directly from FalloutNV.exe. It still pulls up the launcher, but that allowed me to get the game running when it was stuck in "launcher loop."

I tried it out and still no go, i dont understand whats up with this but thx for responding.

http://www.oldblivion.com/sm/index.php?PHPSESSID=0c25cf7ae2446df346e6788026722bf0&topic=5831.msg76421#msg76421

I'm believe this is the same file (the download links are broken, so I can't be sure); if it is, then yes, it's been around for a while.

Also, VirusTotal http://www.virustotal.com/file-scan/report.html?id=794dfbd1b0b0c9f0081166c4a58b07051fe426bac67dd51562306fd1e586dc79-1287600614, which is somewhat reassuring.

Nice find, that does make me far less concerned, honestly, as I would expect that a file that's been around since Oblivion (scratch that, it was from OldFallout3, not Oldblivion) would have made it into virus pattern files by now if it contained something horrible.

Here's the post by the guy who supposedly made it (as part of the OldFallout3 project apparently, an attempt to get this engine running on cards that didn't support stuff like the facegen features):

Interesting. Is this a problem with the engine since Oblivion that's come back for NV? Perhaps Obsidian used a version of the engine that didn't include all of Bethesda's previous bug-fixes...?

No, I had the same thing happen. Same exact hotfix.exe.

The fix works, but it starts loading a ton of trojan viruses in the background. Among them is one that overhauls your start-up with a fake anti-virus software you can't minimize on your next re-boot.

This DLL was obviously modified to include malware. Do not use it.

Thanks to the OP for this, I just installed it after trying everything else: ToggleEmotions, changing iFPS, yelling at my computer...

Now it works silky smooth, and I just killed 5 Viper Gang Members to test it.

And to the naysayers.... is being able to play New Vegas lag free worth the risk that your computer may be infected with rootkits and etc etc? If you are a true fallout fan like me who has waited 10 years to play this game... the answer is: Hell Yes.

The thread that file was in is actually about Fallout 3, not Oblivion. Also:


Everything old is new again.

I scanned this with Microsoft Security Essentials and Malwarebytes and it came up clean

I've just played for about 2 hours, totally fixed my issues.

Sooo than the best fix is to use the one off of the MS site? If thats the case am I looking for the latest DirectX9 version?

Thanks! worked for me! Was tired of getting 15fps with quad-sli GTX295's.

Here is the VirusTotal scan of the .dll for anyone that thinks its infected:

http://www.virustotal.com/file-scan/report.html?id=794dfbd1b0b0c9f0081166c4a58b07051fe426bac67dd51562306fd1e586dc79-1287601261#

Fix works perfectly, scanned with AVG and Malware Bytes and came up with nothing. If there is anything that is giving off virus alerts, it might not be the file, but the megaupload site.

There is obviously a clean version of the DLL that fixes the problem, but I wouldn't know where it was found before this one was modified.

This is riddled with trojans, it is not safe to use. That's all I can say about it.

This fix works PERFECTLY!
Smooth as butter with ultra settings now!
NPCs no longer cause massive FPS drop!
Thank you!
