Fallout: New Vegas Game Fixes (Crashes, Audio Issues, Lag, Saving, etc)
Last Updated on Monday, 29 December 2014 10:53 Written by DarkKnightH20 Tuesday, 19 October 2010 07:43
Fallout: New Vegas is highly addicting game. It is also full of numerous glitches and errors that can prevent you from playing the game easily — like game or launcher crashes, audio problems, quick save / auto save issues (overall saving issues), game lag / stuttering, etc. I’ve compiled a list of pc game fixes that will allow you to play this game with NO problems at all. There are also xbox game fixes listed, but they’re not as reliable as the pc game fixes since there are less tweaks you can perform.
If you still have errors with the game, please do comment and I’ll try to help you out. Just make sure to backup any game files that you may have to modify. This is important! And for those of you viewing this page who have not played the game yet, check out this Fallout: New Vegas Review for information on how it plays
Oh, and when making requests for help, be sure to list what PC game fixes or Xbox game fixes you’ve tried already. Also mention what operating system you’re using and your graphics card. If you’ve used a pc game patch or Xbox game patch, that’s worth mentioning as well

This game page is divided into SEVEN sections: Errors, Crashes, Lag, Audio Problems, Problems Saving, Misc, and Xbox 360. Navigate accordingly between the Xbox Game Fixes and PC Game Fixes.
For some of these tweaks, you may have to locate your Fallout.ini or other INI files. Below are common paths to these files and other files. Simply replace “USERNAME” with your actual username.
C:\\Users\\<USERNAME>\\Documents\\My Games\\Fallout New Vegas\\
C:\\Documents and Settings\\<USERNAME>\\My Documents\\My Games\\Fallout New Vegas\\
C:\\Documents and Settings\\<USERNAME>\\My Documents\\My Games\\FalloutNV\\
This section pertains to general errors with the game and how to troubleshoot them. These errors do not crash your game. That problem is covered in the next section. These errors generate an error message that may or may not prevent you from even playing the game.
“Not compatible with 64 bit Windows” error
After downloading the game, Steam will decrypt it. When running the game afterward, the above error may occur. despite the fact that the game CAN run on Windows 64-bit.
- 1. Close Steam
2. Re-open Steam
3. Re-verify your cache.
It should start decrypting again and *should* run fine now.
Crashes are one of the worst problems to experience and this game is plagued with them. They’re easy to solve though so do not worry.
“Game Launcher Crashes”
This can be caused from a couple of problems. Try one or more to get rid of the error. This usually happens for a non-Windows XP operating system, such as Windows 7 or Windows Vista, but it CAN happen on Windows XP. Note that if you have Windows XP, the compatibility mode solution will do nothing for you, so try one of the other methods.
- 1A. Load the game folder and set each EXE to run in “windows XP” compatibility mode (right click the exe’s -> properties -> compatibility -> check “run this program in compatibility mode for” -> select “Windows XP (Service Pack 3)”
- 1B. Do NOT run the game shortcut created on your desktop. Load Steam directly instead and select the game.
- 1C. Validate your game files
- 1D. Update your drivers
- 1E. Reinstall the game
“Game Crashes After Cinematic Introduction (Intro Scene)”
You may be missing an important DLL file, especially if you are on a newer version of Windows. This error may pertain very well to DirectX 9. Thanks to ABC for alerting us of this method.
- 1. Download the dx9d9.dll: HERE (Nexus)
2. Put the file in your game folder
If that doesn’t work, then try the following:
- 1. Load the “fallout.ini” and “fallout_default.ini” (be sure to set both to NOT Read-Only and make backups of both files)
2. Locate SMainMenuMovieIntro= and delete the following lines:
sIntroMovie=Fallout INTRO Vsk.bik
- 3. Save the files, then locate Fallout INTRO Vsk.bik and rename it to whatever you want (i.e. Fallout INTRO Vsk.bik BAK)
The problem should now no longer occur depending on what was causing the crash on your computer.
A lot of people experience lag with this game. It can be caused by multiple reasons.
“Game Stutters / Lags Randomly” (NOT NVIDIA-Specific, Look at Next Game Solution)
This issue seems most common with NVIDIA graphics cards, though it is reported that some ATI graphics cards are having the issue too. This usually happens when multiple NPC’s are nearby or after killing something. It isn’t related to having a low-end system, as even some high-end systems have this problem. This is a “general” solutions. Look at the next solution for one specific to NVIDIA.
- 1. Upgrade your graphics card drivers (NVIDIA and/or ATI) to the latest version. These generally provide performance enhancements for specific games, as well as fixes.
2. Turn off kill cinematics
3. When possible, apply the latest patch for the game
Again, if you are using a NVIDIA card, first follow the PC game fix listed below, and if that doesn’t work then try the steps listed in this one.
“Game Lags and Stutters / Choppy Graphics or Frame Rate / FPS – With NVIDIA Graphics Card”
So, unlike the above PC game fix, this is aimed specifically to help those with NVIDIA video cards. Note that if you do NOT have this issue, it has been reported that older drives don’t have this problem with the game, and that newer drivers do play the game without issue at this given time (October 19th, 2010). This WILL be solved so don’t feel as if you will never be able to update your drivers again. On the contrary, as mentioned above, it will improve your performance eventually once more updates come out.
- 1. Add a custom NVIDIA Game / Applications profile for “Fallout: New Vegas”
2. For that profile, change the “Power Management” from “Adaptive” to “Max Performance”
That *should* get rid of your problem. For those having trouble locating this feature, go to–
My Computer -> Control Panel -> NVIDIA Control Panel — and it’s under “Manage 3D Settings”. Here’s an image of it (click the image to enlarge it)—
It is reported that this option is “Available only for the GeForce 9 series and above”.
“Game Lags and Stutters / Choppy Graphics or Frame Rate / FPS – With NVIDIA Graphics Card PART 2”
As of right now (October 29th, 2010) the most recent NVIDIA drivers are release 260.99. Upgrading to these drivers is suppose to add:
Plus a lot of other features. Information can be found From NVIDIA on what such an upgrade entails.
“Game Stutters / Lags Randomly” (ATI Graphics Cards)
A hotfix has been released by ATI to help solve the problem of lag on their ATI cards! Get the hotfix HERE. Make sure that it’s compatible with your ATI card otherwise get it elsewhere from their website.
AMD Catalyst 10.10c Hotfix Features:
OpenGL 4.1 beta support
Support for the new Morphological Anti-Aliasing feature
Dead Rising 2 – Crossfire profile (Resolves negative scaling)
Crossfire Performance Improvement for:
Fallout New Vegas
Hopefully if you have an ATI card, that’ll have helped you. Otherwise, try some of the other methods as well. Many have the best results when using this hotfix in conjunction with the DLL fix. Also, though users with a crossfire configuration are suppose to have the greatest improvement with this hotfix, single card users will benefit too.
“Game Lagging / Stuttering From Direct-X?”
This is the same solution as the above DLL crash fix method. Some of you may not be crashing from not having this DLL, but instead may be suffering lag and game stuttering.
- 1. Download the dx9d9.dll: HERE (Nexus). Also download d3d9.dll from here.
2. Put the files in your game folder
“I Am Still Lagging! What Else Can I Try?”
Bummer! You can attempt to modify your Fallout.ini file yet again to combat this. This method makes use of VSYNC.
- 1. Load your Fallout.ini file and make sure that it is NOT Read-Only
2. Make the following change and then save–
iFPSClamp=0 to iFPSClamp=60
“Is There Anything Else I Can Do to Stop This Lag!?”
Yes! One of our users commented on a method that has helped him and many others stop their lag.
- 1. In your console type in ToggleEmotions
You’ll have to type this in every time you play the game, but as I said, it fixes the problem for many. Thanks Auutumn!
“Is There a Way to Help Lessen the Lag?”
One of our visitors just posted a great tip on how to help lower the amount of lag being experienced. Thanks gr0x!
- 1. Right Click Falloutnv.exe -> Properties -> Compability -> Check “Disable Visual Themes”
Your audio messed up? Is there NO audio? Things of that nature will be listed in here, as well as the steps taken to resolve the problem.
“My Game Audio / Sound is Messed Up” (i.e. no sound or timing of sound is off, etc.)
This is usually solved by updating your audio / sound drivers.
- 1A. Update your your sound card drivers
1B. If not remedied yet, disable 7.1 or 5.1 sound output. Use standard 2.1 audio.
1C. Try using analog instead of optical audio output* (thanks OmniNegro).
1D. Put the game into Window Mode (oddly enough, this solves the problem for some)
If that doesn’t work, then the problem below may be what’s causing your audio issues.
“My Audio / Sound is STILL Messed Up, How Else Can I Fix It?”
If this is the case, it may be a problem caused by the FFDSHOW codec that many often install from either codec packs or manually to watch videos on their computer. Here are your options:
- 1. Uninstall the FFDSHOW codec via Add/Remove Programs
- 1. Load a video so that your FFDShow Audio Codec pops up in the system tray
2. Right click the system tray icon “ffdshow audio decoder” (NOT “ffdshow video decoder”) and then select “ffdshow Audio Decoder”
3. Select “DirectShow Control” in the list and then click the “edit” button next to the “Don’t use ffdshow in:” option
4. Click the “Add” button and select the Fallout EXE for 32 bit or 64 bit version(s) installed
“My Sound Still Isn’t Playing! What Else Should I Try?”
This was a suggestion by one of our users. Thanks Andres!
- 1. Load the game and pause it (hit the Escape / Esc Button)
2. Hit ALT + TAB and open the Task Manager (CTRL + ALT + DEL)
3. Under the Processes tab, Right click the Falloutnv.exe -> Set Priority -> HIGH
“Are There Any Other PC Game Fixes Fore Messed Up Sound?”
Fortunately, yes. As suggested by Alex (thanks!) try the following pc game fix–
- 1. Load the Control Panel and open “Sounds and Audio Devices” -> Click “Advanced” Under Speaker Settings -> Click the “Performance” Tab
2. Set “Sample Rate Conversion Quality” to “Good” (the bar to the very left)
Done. That’s all there is to it.
“Maybe It’s My Sound Card?”
This was a suggestion by one of our users. Thanks gr0x! It turns out that his sound card did not support DirectX DirectSound Acceleration.
- 1. Go to Start -> Run — type in dxdiag and hit OK
2. Click the “Sound” tab and then click “Test DirectSound” and allow all of the tests to complete
3. If you any errors occur, use the slider to turn off Hardware Sound Acceleration by dragging it all the way to the left so it’s labeled as “No Acceleration”
Note: Even if you don’t have any errors during the test you can try turning off the acceleration to see if it solves your problem. Turn it back on when you are not playing the game any longer.
This category is about problems with quicksave, autosave, and general saving for the game. This REALLY gets on people’s nerves since they keep on losing all their data. Note that there ARE patches being released by the company so apply those patches BEFORE even attempting any of these pc game fixes. You may find that the patch will solve the problem for you and it’s better to use a legitimate fix rather than tweaks when it comes to something as important as your saved data.
“The game won’t save, or my saves are overwritten, quicksave and autosave do not work, or I am having issues saving the game”
Unfortunately, this game is plagued with save issues. The pc game fix is very annoying as well, so my suggestion is simple;
Do NORMAL, manual saves instead of QUICK SAVES for the time being until a patch is released. To speed this up, do the following–
- 1. Hit the ~ key
2. Type save “savefile1” and hit enter
3. When you need to save again, hit the ~ key like before, then hit the “up” arrow key to bring up the previously typed in save command. You can overwrite or rename the save file.
4. To load your file, hit the ~ key and type in load “savefile1”
“How Can I Recover My Saved Data From QuickSave / AutoSave / Etc?”
- 1. Locate the save files folder — My Documents\\My Games\\FalloutNV\\Saves
2. Find files that have a *.bak extension. If you cannot see extensions, enable them through these steps.
3. Rename the files with a .bak extension to something without the .bak extension (i.e. “autosave.fos.bak” to “autosave.fos” and then rename your old “autosave.fos” to autosave_old.fos”, as they .bak may have your newer data).
“There Are No Game Save Files! How Can I Find Them / Fix This?”
- 1. Navigate to your Fallout.ini in the FalloutNV folder and set it to NOT Read-Only
2. Open the file and search for SLocalSavePath using CTRL+F (find option)
3. Look at the path it has listed to make sure there is an actual save folder (i.e. SLocalSavePath=Saves\\ ). If it isn’t present, make the folder yourself, otherwise the save files are located there!
“How Can I Fix The .BAK Save File Issue to Prevent Incorrect Save Overwriting?”
Some people are having luck with this method, while others are not. Be sure to back up your save files regardless before doing this.
- 1. Follow the steps above and load the Fallout.ini
2. Make the following change in the file:
CHANGE iSaveGameBackupCount=1 to iSaveGameBackupCount=0
Again, make sure to do a manual backup of the save files! And only do this if the latest patch isn’t working for you!
“Is There Anything Else to Help Fix Saving the Game?”
Yes. I keep talking about files being “Read Only”, but it may be that your entire SAVE FOLDER is “Read-Only”.
- 1. Navigate to your Save folder and Right Click it -> Properties -> Uncheck “Read-Only”.
Why it’s set to “Read-Only” on some PC’s, I do not know. But hopefully your game will be able to save now. Thanks Jason!
This category is full of miscellaneous problems with the game that don’t cause the game not to play, but do cause annoyances. For this game in particular settings reverting happens to be a very common problem. You’ll find solutions to this problem and more here.
“Language for Game Not Changing After Selecting Different Language”
- 1. Select the language you wish to use for the game
2. Close Steam
3. Re-open Steam
A game fix / patch will be released to allow for the language to be changed without restarting Steam.
“When Installing Game from Disc / DVD / CD, Steam is automatically launched (executed), validates the game files, and then begins to download the the game files instead of installing the files from the actual disk.”
- 1. Load Steam and Select the Library
2. Right click the game -> “Delete Local Content”
3. Insert the disc into your DVD drive
4. Close Steam
5. Go to Start -> Run and type in–
“C:\\Program Files\\Steam\\Steam.exe” -install E:
Make sure to replace the path to Steam with the path to your Steam.exe. Replace the letter “E” with your DVD drive letter. Then press OK.
The installation should now use the files in the DVD rather than downloading them from the internet now.
“How Can I Fix Mouse Acceleration Problems?”
The game’s mouse acceleration may be annoying you. You’ll have to edit a few INI files to fix this.
- 1. Make sure the game / Steam is closed
2. Navigate to My Documents\\My Games\\FalloutNV and set “Fallout.ini” and “FalloutPrefs.ini” to NOT Read-Only (right click each file -> properties -> UnCheck “Read-Only”)
3. Add the following to the [Controls] section of each file–
- 4. Next navigate to “C:\\Program Files\\Steam\\steamapps\\common\\fallout new vegas”
5. Set “Fallout_default.ini” to NOT Read-Only and add the same lines above to the [Controls] section
6. Next navigate to “C:\\Program Files\\Steam\\userdata”. There will be a folder here with random numbers as its name. Open it, then sort by last modified (right click folder -> “arrange icons by” -> “last modified”). Open the MOST RECENTLY modified folder that is NOT “config”.
7. Make sure “falloutprefs.ini” is NOT Read-Only, and edit it just as you did with the previous INI files.
That was a lot of work, huh? Easy, but tedious.
“Game Graphics Settings Aren’t Saving / Keep Reverting”
You may be trying to alter your graphics settings to improve game play and find that the settings either are not saving or they keep reverting to your previous settings. This is likely an issue with Steam Cloud.
- 1. Close Steam / the game
2A. Turn off Steam Cloud Synchronization under the update tab of the game via the properties area of the steam game list (or play in offline mode) – Thanks dviper785
2B. Set FalloutPrefs.ini to NOT “Read Only” (right click -> properties -> uncheck “Read-Only”). It’s located here: My Documents\\My Games\\FalloutNV\\FalloutPrefs.ini
- 2C. Delete the INI files (FallOut.ini and FalloutPrefs.ini), then launch the game directly
“How to Activate DLC and Bonus Content?”
- 1. Double click the game entry in your Steam library
2. Select “Data Files” in the game launcher menu
3. Select the game content accordingly that you wish to have available
“How to Activate / Play Hardcore Mode?”
You may notice that “Hardcore Mode” is NOT enabled / clickable / is grayed out / non-selectable / etc. Well, this is because for it to be enabled, you must first leave the house in the beginning of the game. It will then be enabled
This category is NOT for PC gaming problems, but for Xbox 360 gaming issues. There are less xbox game fixes available for these than there are pc game fixes because generally, you must wait for a patch.
“My Xbox 360 Fallout: New Vegas Game Keeps Crashing / Freezing”
As mentioned above, there isn’t much that can be done here. But I will give all the suggestions that I can that MAY or MAY NOT be able to fix your problem.
- 1. Make sure your disc is clean
2. Clear your game cache (follow directions below)
3. Run the game from the DVD instead of directly installing it on to your Xbox 360
4. Apply the latest patch / patches when available
“How Do I Clear My Xbox 360 Game Cache?”
This might solve your particular problem, though nothing works as well as a patch.
- 1. Load your Xbox 360 and go to My Xbox -> System Settings -> Memory
2. Select your storage device, then press Y on your Xbox Game controller
3. Select Clear System Cache (or press X, X, left bumper, right bumper, X, X)
4. Choose “Yes” when asked to perform maintenance mode and let it do its thing
I hope your problems have now been solved. If not, feel free to comment about the error you are experiencing and I’ll be sure to get back to you within a day or two. Also, if you know any other game fixes (pc game fixes or xbox game fixes), I’d love to hear those too Thanks.
