Here are my system specs before we begin, I don't need to post a DxDiag as I already have the recent drivers (the 11.8 beta drivers) for everything. I just upgraded my ATI graphics card from the 5750 HD which the game worked fine on to the beast 6850 HD graphics card... which every other game works fine on. New Vegas is just a buggy mess of a game now, especially if other games work fine. Now, to the specs:

Windows 7 64 Bit

8GB of RAM

AMD Phenom II 1035T with 2.66 GHz and six cores

ATI Radeon HD 6850 with 1GB of VRAM

All latest drivers installed, I do well to update often, and I got the beta drivers even; hoping to grab the complete drivers soon for 11.8.

This is a huge problem that I notice has been spreading here for you all. I sympathize with you guys, as it's happening to me too; right after I start a new game and right after it does the very first loading screen of the game. I refuse to try any of the fixes because there is no reason for me to do any of them for a game that came out so recently and a game that should already be stable with my stable system that RARELY HAS PROBLEMS with anything. What's the matter with you Bethesda? Seriously!

I clocked in about 42 hours, never finished the game awhile ago because I wasn't strong enough and the final boss was too hard for me. So after several months, and after my graphics card upgrade, I wanted to enjoy the game with hopefully better performance (apparently people with nice systems still get performance issues, what an unoptimized mess of a game). So I started it up again, with the Dead Money DLC I got awhile ago and should try out in this playthrough. But the game crashed, and I may never be able to play again. I am attempting to reinstall the game after verifying integrity of game cache didn't work. For some reason, the game sets the graphics to low after detecting my hardware, when before it set it to ultra... this makes no sense, this is what you get Bethesda for allowing the usage of a 5 year old graphics engine! THIS is what happens!

I love this game too, but I will never be able to play it again. Some of the people here still have problems even after attempting the fixes, so I am not even going to try; and why should I? The game should be FINE from the get go, like ANY OF MY OTHER GAMES. I might as well settle with Fallout 3 GOTY edition, even if Fallout 3 is somewhat inferior (in VATS, the game is too easy, 40% damage reduction, a HUGE flaw no one noticed). I'm just sick of problems that I should of left behind me after getting Windows 7 and upgrading my PC into a more formidable gaming beast!

ussually windows on 64 bits it is a little demanding for any portion of software that were first made for a 32 bits system...and if I remember corectly my 64 bits 7 never run fallout nv...not because of a bug or a compatibility mode..but bcs I think he never like too much fallout..

Then I can try 32 Bit compatibility mode for the game, if possible. Maybe some of us should try various compatibility modes for FalloutNV, I don't want this game to be dead for me just yet!

Well, I tried putting it in Windows 7 compatibility mode, but it didn't work.

I reinstalled the game on Steam, and reverified integrity of game cache, but it still doesn't work. It always seems to have to download a 188 MB file every time I verify the game cache. I tried messing with the data file manager with my mods (which I only have two, vanilla NV and Dead Money, even checked load loose files). Really, what the hell is going on?!

Well, it's time to put New Vegas to rest, I will never be able to play it again; what a waste of money.

Be sure that you know that this is Obsidian's work. A developer that deserves its reputation of releasing inordinately buggy games, lying to their publishers and consumers, and blaming the result on someone else. They previously apologized for FNV and later retracted the apology and now claim in their automated response spam letters that the game was made before Windows 7 was released. So they claim it is the fault of Microsoft. This is also the same developer that gave us lousy Alpha Protocol and craptastic Dungeon Siege 3.

This sure is funny targeting obsidian for this. Lot of ppl have had problems with the engine since oblivion so let not start to blame left and right even though its a funny to blame obsidian for this as all the tools are bethesdas. I myself have had lots of problems with all 3 games and lets face it the engine is already really old. and the engine was never actually to be used with win7 as its already a grandmother of graphic engines.

Does it crash after the cinematic when the actual game starts or during the cinematic ? Do you have a bunch of codecs installed...
If you have FFDSHOW try and disable its use with FalloutNV exe for starters

I had way more problems with FO:NV than with FO3 or Oblivion, or Morrowind for that matter. Clearly Obsidian arent as good as Bethesda at using these tools, and i'm quite sure they added or changed stuff because GECK for FO3 isnt the same as GECK for FONV, so there must be changes to the toolset, made by Obsidian. Even the editor is highly unstable (not sure how it is for FO3, didnt use it).

The LOD is incredible crappy, flickering textures, LOD's that doesnt disapear etc (yeah even default without any mods). The game is also very unstable for me, far more than FO3 which run great.

FO:NV also has a bit of stuttering, FO3 was almost butter smooth for me even when loading new cells..


One thing that does seem to help with stability is the 4GB patch (search on TESNexus), Im also on Win7 x64, 8 GB RAM.

This issue isnt fixed yet?? I installed the game the day it came out, it failed and crashed. I come back 5 months later and its still broken? WTF I bought it on Steam too, you would think they would be able to realease a patchec working copy and when u try to get help its just links to abandoned threads. Nice one gamesas

Yeah guys, it's just sad because Fallout New Vegas isn't a bad game either; I love it, and it's sad that it is having these problems... so if they are never going to fix this crashing issue I am not going to do anything because I shouldn't put in so much effort just to fix a game that worked for me from the beginning. I won't be able to play it ever again; this is a sad day for me as a gamer indeed...

10.7 here with a similar rig as yours. Have you tried the final 10.7 drivers yet? Using some unfinished drivers is bound to call for problems, y'know?


So you do have problems with your rig?


Speech skill of 90 does help with the Legate... actually at lvl30 with companions this one should be cake even with guns blazing...


Why? The game refuses to load your safegame now?


Sounds like a good old problem with chipset drivers. When these are not "properly" installed, the game and DX cannot detect your graphic card propertly. Been a problem for a long time and a many games now. Let me guess, you are using Beta Chipset drivers too?


I am running FNV under W64U7, so I can assure you that's usually not necessary.


Sounds like the main suspect for the usual culprit.

Have you tried using a retail disc for a reinstall?

Steam's copy protection is crap. Period. Always will be. FNV is not the only game suffering from that. :confused:

I am using beta drivers AND ALL OF MY GAMES FUNCTION JUST FINE... don't say it's 'been a problem for awhile'. No it hasn't! My games still work!

My system IS stable, I barely have any problems with it and my games, it's only NEW VEGAS that's having problems. The recent problem with a game was Metro 2033 with my not so good gaming computer I previously had that was Windows Vista. But now Metro 2033 works just fine!

I am going to uninstall the beta drivers for everything and see if it helps, but otherwise, I just don't know what to do to fix New Vegas.

Didn't you write that FNV doesn't run for you? Now I am confused.


Well, for the last 15years or so it has been a problem that people did not install working chipset drivers, and their games had problems. Like with AGP graphic cards. Same problem is with PCIE and some games. That's what I've meant. Whatever.


I think you misunderstood me in your rage. :shakehead:



Try to get rid of Steam for your FNV. Or try a copy of Vegas without Steam copy protection. Like from a retail disc of sorts. The Internet can be a usefull place at times, y'know?

The game works fine now after uninstalling all 11.8 beta drivers.

For one thing, I had those drivers for Battlefield 3 Alpha Trial, because I was invited to it. Those drivers claim to improve that game's performance... even if the game ran well for me, I was hoping it would get rid of the strange graphical artifacts, but since it's an alpha it still had the artifacts regardless. The performance in Crysis 2, well, looked like an improvement but the game runs well for me now regardless.

So yes, it's not Steam copy protection; I trust Steam, as I haven't had any problems with it so far either.

Maybe if others have the beta drivers, they should attempt to uninstall them and get back the 11.7 drivers? Try out this fix everybody!

Retail or not you cant get rid of steam. FNV uses steam period whether you buy it on steam or retail. There is no steam-less version.

Yeah you can get rid of Steam, might also help with stability, for me it didnt get worse at least..

Not sure those forums allow such discussion though, probably not.
