from the looks of it you're the only one with an ego thats connected to your pc lol

the dll doesnt just force newer cards to use dx9. the game already does that. what it does is force newer cards to behave like older ones. thats why you may lose image quality.

Well, without the dll, I get the same identical crappy framerates in New Vegas whether I have the game set to 800x600 with all settings low, or 1920x1200 with everything on Ultra!

Again that card is fully directx 9 card as i looked up, so what image quality are we talking about since the game are dx9 ?

Only thing that that card would done worse then my new card is performance.
And possibly a couple settings forced under nvidia controlpanel like transparent aa etc.

Call me crazy but I agree with this guy 100%.

I also have a computer able to Ultra both FO3 and FONV but in FONV I get stutter and constent framerate drops, but with the .dll everything is as smooth as butter with NO loss in image quality.

I think you guys saying you are loseing image quality are just looking for something to talk/complain about.

This has NOTHING to do with directx 10 or directx 11. The game is DX9, there is NO reason why a DX9 game would work improperly on a DX10 or DX11 feature set video card when they are 100% backwards compatible. The only difference is the hardware support for the new versions of direct x

I edited my original post to state what the difference is,

Without the .dll (and an nvidia card since I don't have ati), rendererinfo.txt will point to nvidia's main 32-bit driver dll file - nvd3dum.dll

With the .dll file, it will spoof the game into thinking you have a 7900gs and load nvidia's older main driver file instead - nv4_disp.dll

(Fallout 3 does not load nv3dum.dll at all, only nv4_disp.dll so this d3d9.dll won't help that game at all,just in case you were wondering)


nv4_disp.dll doesn't exist on my system at all, so I have no idea what it does in it's absence. Interestingly, the game folder has a version of ati's main driver .dll file but I don't know why and there is no nvidia file in the folder

I don't think this has been mentioned yet. But there is a different dll fix available that spoofs a newer card, a 8800 GS i think, which evidently fixes some of the image quality problems people are noticing, such as the vegetation and lower quality shaders. This one is for ATI cards only.

http://www.newvegasnexus.com/downloads/file.php?id=34970

Note as the description says that this file doesn't fix any of the current problems with crossfire.

Nvidia owners shouldn't use this, it's using ATI's renderpath:

NVIDIA Geforce 8800 GS
aticfx32.dll
RenderPath : BSSM_SV_2_B
PStarget : ps_2_b
PS2xtarget : ps_2_b
Shader Package : 17

It'll run slower because you're using the wrong rendering method for your graphics card. It might say it's an nvidia 8800GS but it should not be using ati's driver file (aticfx32.dll) or PS 2.0b which nvidia cards no not support. Or shader package 17 which are ATI shaders. Please do not use this if you have an nvidia card

I already stated what the difference and I just did a test. It's the emotions, I talked to Benny and the way he squints his eyes is different if using one method versus the other (same as disabling emotions).

This is just a guess but because my GPU utilization goes down without the .dll when people are talking and also because the game mainly uses 1 thread, I am going to guess that they added subtle facial expressions to make the NPCs less stiff than in Oblivion/FO3. I am also going to guess that these are calculated on the CPU but still within the same thread as everything else. That's just a guess, I could be totally wrong

Can you show me where to find the 64 bit version of atimgupld.dll? And aside from replacing that file was there anything else you had to do to get it to work? (I am already using the ATI version of the d3d9 fix). Thanks.

Thanks for the info. Strange that it runs at all for me then using that dll with any visual difference, you'd think it would just crash immediately. I will update my post so I don't mislead anyone to using it with their nVidia card.

Just in case people didn't notice, there is a new release of the current nVidia drivers with Fallout 3 specific fixes. It seems to have fixed the NPC issue for me, I've removed the drop in dll and I'm not getting a slide show when looking at more than 3 NPCs. Obviously this removes the graphical issues as well, like the majority of the z-fighting and flickering horizons.

http://www.nvidia.co.uk/object/win7-winvista-64bit-260.99-whql-driver-uk.html

Oh it will work for whatever reason, but the lighting will gltich and performance (in some parts) will suffer. I know this because I followed a "performance tip" for fallout 3 once that consisted of copying shader files over to 'force 3.0 shaders'. But there was no difference in visual except lighting was off in parts and some areas chugged really bad when they didn't before.

Well, I'm going to keep using the .dll file (nvidia 7900gs original one) for one because it's harmless and I'm pretty sure any difference in visuals is all in out heads EXCEPT I'm 95% sure that it togglesemotions off (so no need to do from console). I'll stop worrying about it for now and just play the game, hope a fix comes out. Week 1 sales figures said PC users made up 10-15% of 1.4mil sold... So 140k -210k PC copies and the only ones complaining on web forums probably total in the low hundreds if even that high. We're a minority for now until the gameplay bugs like quest breaking glitches and creatures stuck in rocks are fixed for the console users

I get extreme z-fighting with that dll. Particularly on the horizon. Whole mountains flickering in and out of the sky texture, removing the dll removes the z-fighting. It definitely affects visual quality.

Aren't we playing Fallout New Vegas though? /facetiousness

I'm wondering if it was simply a mistype in the name, or if this is really a Fallout 3 update?



I see no difference on my end. :shrug: (Other than the lack of FPS without it.)

I'm using these, but I still have slowdown with NPCs talking or on screen without the .dll. Performance on my GTX 460 is noticeably overall smoother though, excellent driver release. I still get flickering on horizon every now and then but this happened in Oblivion and FO3 and is something that doesn't bug me much

That's all very good information Mr. OP but still, the basic issue is that FNV won't run worth a hoot for most of us. I am not a puter junky in the least so I come to these forums in the hope some brilliant minded customer has found a solution to the problems that Bethesda stuck us with. I actually did the .dll install the other day and had a noticeable improvement on the NPC/Lag problem. I do note that the video graphics defaulted to medium quality and originally it defaulted to ultra. Now, even though I don't understand a thing about what you are saying there are a few things I do know:

1. my puter which is a big expensive Alienware has the NPC lag/stuttering issues.
2. my drivers are up to date
3. i want to play the game
4. the .dll seemed to help
5. Bethesda never fixed the significant FO3 crashfest issues
6. I have no confidence that Bethesda will fix the engine issues in FNV either
7. I am therefore dependent on all of you geniuses out there who can do Bethesda's job for them

By the way, notice how there is a complete lack of communication from the Developers on this problem. Until one of the customers solves it for them don't expect it in a patch. Yes, I'm fuming that this was released in the condition it is in as it was nothing more than grab the money and forget the playability (i.e. screw the customer) mentality.

Anyway thanks for all that info on the .dll solution as I am certain everything you are saying is correct. But at least for now, I can actually play the game even though the graphics now leave a bit to desire.

Ah I see. The image quality increase was probably all in my head too, i've been tweaking so much the last two or three days I don't know what's what anymore. The new slow down in Camp McCarren and the Strip likely gave me the idea that it must look better if it's running slower. /agree with everything else as well. I'm hoping the PC specific stuff gets cleaned up in a month or two once gameplay issues on the consoles have been sorted.

No it's not a typo. Any driver fix that works for Fallout 3 is going to do the same thing for New Vegas.

As for the visual quality, there is a noticeable difference in the z-fighting, no question, but if that doesn't bother you then it's identical.

The FPS is much smoother with 260.99 but I still lose about 10 FPS without the DLL when Im near multiple NPCs. The difference before 260.99 was about 40 FPS

It should include NV in the fix then. :shrug: (Forgive the OCD moment.)

You are going to have to tell me what is different in those screens because other than character/cloud positioning, they look identical to me. (But I can be a bit slow at times and maybe I'm just missing it.)

Only thing that new driver helped my gtx 295 was getting rid the flickering mountains in bakground.

Stil stutterfest without the dll file.

is the 7900 GS the only dll file that works, what if we use alittle newer version for the 800`ss series will that make it bad again ?

Well New Vegas is Fallout 3. Same engine, same game when it comes to drivers as far as Nvidia is concerned.

There is no difference between the screenshots, that was the point. Some people were saying that using the DLL reduced the quality of the visuals, which it does in some very minor ways (the z-fighting like I said) I was just showing people how minor/non existent the differences were.

I just downloaded it from my dll.com..renamed the default atimugulpd.dll library and dropped the new one in.

When you download it there will be several files in it...just scroll down and look for the 64 bit version...copy it to the New Vegas folder...drop it in there.

And that's it...

It stands for ATI Multiple G P U Profile...

Will not help Nvidia cards...

No the ATI dx9.dll ( at Nexus ) is for all ATI cards.

The atimuglpd.dll library exchange is for Crossfire only....

I don't see a difference either. I get flickery mountains one way or another. Bottom line is the .dll you discovered indeed makes the game much smoother even if we don't know exactly why. But still would be interested in knowing!

Thanks for the info but i was able to find the answer here:
