New Vegas is built on the same game engine as Fallout 3. Unfortunately, New Vegas has also inherited some of the bugs its predecessor had. This does not mean it’s full of bugs. It’s a very famous game. To avoid Fallout New Vegas crashes and enjoy improved performance, here are some fixes that you can apply.
1. Change Settings from INI Files
2. Update Graphics Driver and DirectX
3. Fix and Defrag the Registry
4. Run the game in Compability Mode and as an Administrator
5. Change Game Settings
Change Setting from INI Files
Some multi-core hardware incompatible with the game may result in Fallout New Vegas crashes, freezes, and BSOD errors.

1. Click Start | Documents.
2. Double click: My Games | FalloutNV
3. Open a file named fallout.ini
4. Look for the string named bUseThreadedAI=0
5. Replace 0 with 1

10. Double click the file named fallout_default.ini
11. Do the steps 4 to 7 above.
Update Graphics Driver and DirectX
Keep your drivers up to date. Download a latest version of the graphics driver. Download DirectX from Microsoft’s website. This will prevent Fallout New Vegas crashes due to poor drivers.
Fix and Defrag the Registry
Windows Registry is the database containing the information, like user settings, operating system and application data, for the functioning of your computer.
Likewise, the game has its registry entries in the Windows Registry. If these keys become corrupted the game Fallout New Vegas crashes.
Due to random access to the registry (like storing and deleting) the data in it, it gets fragmented time by time. This results in slower performance in retrieving of the registry information. You can defrag the registry to fix errors and maximize the performance of your game.
