You screwed up question 3 you or asking if you use xp which usses dx9c or a dx10/11 card and the answers are yes no n/a'
the answers should be xp, dx10/11 or n/a

Are you using the d3d9 fix.
No, don't need it

Image Quality issues when using the fix ?
not using it

If you don't need it, are you running Windows xp
yes xp
using 2 Nvidia GeForce 9500 GT 1gb cards

Do you have framedrops on a dx11 card in windows7
not using one

by the way i have no problems what so ever thats why i've never tried it.

A word on that particular segment in your post, and of course this is purely my personal opinion - take it for what it is worth to you:

While that particular website does have a lot of good links to useful utilities and such, his advice and frequently voluminous opinions misrepresented as 'fact' are woefully myopic and spread a great deal of misinformation as a result of blatant ignorance and even refusal to actually investigate and/or research that which he proceeds to criticize. I'm not going to go into details but that individual has gotten himself banned from various forums as a result of his behavior and inability to behave in a civil manner, since witnessing those events the dubious credibility of tweakguides declined to pratically infinitesimal. As I said though, it is a decent place for links to utilities and news (from generally credible sources) - but I would call into serious question the validity of anything that comes as personal advice from that site.

Did you play New Vegas before the reinstall ? If so was it worse/better ? Do you get any sort of stutter near a big grouping of npc's ?
Did you update your drivers before/after the reinstall ? could you possibly post some screenshots with a fps overlay ?

Sorry for being so exited but you're the first guy I've met on any of the message boards I frequent that has that setup without any issues.




Will add to the topic for people to make of it what they will, good info. I had no idea, lets not make this about him though.

Are you using the fix: Yes
Windows Vista 32, Nvidia GTX460
Increased performance: Yes, very much so (average framerate went from 30 to 60, no more drop to 15 when an NPC speaks).
Image Quality Issues: No. I've taken comparative screenshots, they are identical in every way.
Quality Settings: 1920 x 1080, Ultra for all settings except AA (none), due to a seperate driver issue that causes white flashes if AA and HDR are used together.

Edit: Your final poll question is meaningless.
Do you have framedrops on a dx11 card in windows7?
I voted No because I don't have Windows 7, but I DO have framerate drops (without the fix) on a DX11 card in Windows Vista.

Edit: Oh, hey! I just checked, and Nvidia has released a new driver. Release Highlights:

?Adds SLI profiles for the following PC games:
?Need for Speed: Hot Pursuit
?Star Wars: The Force Unleashed II
?Fallout: New Vegas
?Improves compatibility for Fallout 3: New Vegas with antialiasing enabled.

I'm off to install it, so I can use AA!

Still cant vote you need to nadd n/a to question 2 and 4 for those people who did not use the fix.
sorry should have said at the same time i said question 3 was wrong .

Hmm did you change question 3 from compatable card to incompatable card ? if not and ot was incompatable all the time then it was right and i read it wrong sorry i'm tired .

Yeah I'm tired and confused as well and I apologize for this poll failure ;(, I'll make a final attempt at sorting it out and the formatting on the o.p as well

Are you using the fix: No, I don′t have the balls to try something I don′t understand..

OS/Video card/CPU/RAM: Windows Vista 64 bit/ ATI Radeon 4800/ Intel Core Quad Q9950 @ 2,83 GHz/ 4 Gig

Increased performance after the fix: Don′t know, haven′t tried it.

Image Quality Issues with the fix: Don′t know, haven′t tried it.

Do you have framerate drops when close to NPCs: Yes. I do run the game on ultra high settings and highest resolution, but when I turn down settings the problem is still there. Framerates when close to NPCS seem to drop even more when I turn down my settings. Game seems to flow best with highest settings. I do not have the extrem slowdown I have been wittnesing on the internet but I do get low framerates when close to NPCs, especialy at places like Prims crowded casino. This is annoying and takes away some of the games atmosphere.

P.S. My game crashes to desktop every 2-3 h or so.
P.P.S I′m from Sweden so please excuse my english D.S.

You, and the people like you, are the reason bethesda needs to get this fixed. I don't blame you for being unwilling to apply a random .dll you don't know anything about in order to fix the issue, it's sheer common sense in the world we live in today. Furthermore your case is an almost textbook
demonstration of this issue. Almost everyone seems to notice it for the first time in Prims casino.

P.S So does mine
P.P.S Your english looks fine to me.

Yes I did and it was definitely worse. There is some micro stutter but it is random and very rare. I installed the drivers after a format and before I install the game. I haven't got any screenshots at the moment but my fps is 40-60. However, I'm definitely not the only one and there are many people on Youtube with similar setups (Phenom II x4 955/965 and HD 5870s who play with VSync off and have higher fps than me.

Oh you are running two 5870s ? yeah 10.10c would make it better for you with added crossfire support. However that still seems like an awfully low fps count for that kind of horsepower. How does fallout 3 run like around what framerate ?

Using an ATI HD 5770 card on Vista. Ultra graphics settings.
Had framerate issues, the fix worked, no hit to image quality.

Aside: Game runs smooth as silk covered in butter now

I didnt _need_ it, but I was curious to see what it did so I tested frames on max settings. 23 FPS average on my HD4870, then again with the d3d9.dll, got 38 FPS. <.<

So yes I use the fix and it works.

No, I meant people with HD 5870 cards. I'm running a single HD 5870 @ 900/1300 with a Phenom II x4 955 @ 3.6 GHz. Fallout 3 runs better, I always play with VSync on so my maximum framerate is also 60 but my minimum framerate is higher and there is no micro-stutter at all.

I think your microstutter is the same thing as my framerate drops, I walk around and it feels like my movement is stuttering and it gets worse in places that have a lot of npc's. I also don't have it at all when I play Fallout 3 which I have maxed out as well.

update

original dx9
Are you using the fix: Yes
Windows 7 64bit/Video card HD6850
Increased performance: Yes - NV Strip from 14 fps to 45
Image Quality Issues: No. The game resets everything to low after the dll. The card is recognized as HD7900

java generated dx9

The java generated dll works even better and correctly recognizes the card. I just don't understand why there are java builds available in x64 too and i cannot run them.

o.0 and there's a hot fix 2 inject too?

Yes with performance increase, no anomalies, NPC related framerate drops with W7 and GF 9600GT (dx10 card).

I'll jump in. The fixes work. The original one which forces detection of a 7600GT or something like that does reduce the IQ a slight bit on ATI cards because it suggests a particular set of shaders that the ati cards don't do, so it falls back (or something along those lines). When using the other one, which forces detection of the modified 8xxxgt or whatever card, the shader issue is gone and everything looks proper.

The fix is essential, otherwise the framerate is total junk. This FPS problem is a gamebryo specific one, and it happens on both ATI and NVIDIA cards on at least windows 7 (perhaps vista?).

No
Window 7 x64, 4 gigs ram (DDR2), 9600 GSO (768 mb)
Only have drops when in the BoS bunker (the worst), and the kiddies chasing the rat in Freeside. Other than that my frame rate is shockingly high for my antiquated tech.

I still have lots of world to cover so I may do the fix later on.

No. Dont need it and if i did i would wait for OBSIDIAN and or BETHESDA to patch it. I read years ago DLLs can be dangerous.
N/A.
WinXP with all service packs and Radeon 5770 vid card installed aswell as onboard sound. 2gigs of ram.
N/A.
Game plays on ultra settings at a resolution of 1280x1024.

Thanks for asking.

Bumping this thread up to the top again this needs to be discussed IMO.

In my case I still haven't applied the dll fix, because for the life of me I cannot figure out what it does. I still have a sub-par framerate on my system consisting of a i5 760, HD5870, 4GB DDR3, and windows 7. I have tried virtually everything except for the .dll and disabling the heads on characters. ToggleEmotions does nothing, The ati 10.10c hotfix does nothing, forcing a multitude of different settings through CCC does nothing, and finally, as a last resort, lowering all the settings down to low did not alleviate my issues. My performance is fine, as long as I am out exploring the wastes. If I meet a grouping of NPC's hower the entire playing experience takes a nosedive into the awful territory. This is in my opinion unacceptable, and it ill fits both Bethesda and Obsidian that there has been no response to this supposed d3d9.dll fix. If it is a bug or the result of a coding error on Bethsidians end,they should simply inform the community of said issue and subsequently fix it.(Never going to happen probably because they like sales.)


I have scoured every New Vegas related thread I could find and it seems like a very large percentage of people are actually being helped by this fix. Especially the people running high-end systems that are not performing up to par. I am at my wits end in trying to resolve this issue. As I have already spent far too many hours, watching, the well crafted but utterly obnoxious when viewed for the 500th time, intro screens. I hope Bethosidian(something like that I guess) are looking into this situation because it is absolutely heart-breaking for the many fallout fans that are suffering from these issues.




Please call Epic and have them deploy CliffyB to your location, because dear Clifford fixes everything, thank you.

Using this fix - Runs like a charm(Medium-High) on my crappy 8600M GT

You don't need it because you're on XP. The fix seems to be only relevant to systems capable of DX10/11. That means, both a DX10/11-capable video card, AND a DX10/11-capable operating system, i.e. Vista or Windows 7.

The problem is that even though the games runs in DX9, DX10/11 systems are not properly using DX9--they are downgrading to it in a way that negatively impacts performance, especially around NPCs with facial animation.

The DLL file simply fools the game into thinking that you have a DX9-only video card, which forces it to use DX9 properly. It doesn't change or replace any existing files or downgrade performance. It will change your settings to Medium the first time you run with it (due to the launcher seeing 'different' hardware), but once you put your settings back to what you want, you will have the sort of performance you would expect from your system without the extreme framerate drops.

That seems to be one of the running theories, I'll update this post/post further on in the thread with the information I have gathered about it's workings so far.

Are you using the fix: Yes
Windows 7/Video card: Yes - GeForce GT 330M
Increased performance: Yes
Image Quality Issues: No

It made a world of difference for me. Before this fix i wasn't able to play it smooth at lowest setting and now it's really smooth at High quality. I'm using a VAIO F series with Windows 7.

ps : Thanks for the post, i didn't knew there was a fix before i read this.

I have made this topic to expand on my findings, it explains why and how the d3d9.dll works. http://www.gamesas.com/index.php?/topic/1134379-d3d9dll-and-why-it-works/.
