Click 'Add', then browse to your New Vegas folder (Usually in your Steam Steamapps Common folder), and add FalloutNV.exe Scroll down to the 'Power Management Mode' option, and set it to 'Prefer Maximum Performance'. Click Apply, then Yes. Fallout New Vegas should hopefully not crash for you (at least not with the same frequency) anymore!

1. Fallout New Vegas Geck Crashes On Startup
2. Fallout Nv Mods Crash On Startup
3. Fallout New Vegas Crash On Startup No Mods

Just installed Fallout New Vegas.

After some time of game play the game just quit to Desktop without any error messages.Can someone point me directions on why this is happening and how can I fix it?

Running on Windows 7 32-bit, nVidia GTS250 MB.

The game is very buggy, make sure you have the latest patch installed (should happen automatically if Steam is not in offline mode). Also try to install the latest Nvidia driver.

But most likely you just have to wait for a new patch to fix some more of the numerous crashing bugs this game obviously has.

If you have a multi-core machine, you may want to try these instructions: http://www.pdsys.org/blog/post/2009/02/07/Fallout-3-VideoDisplay-Freezes-sound-keeps-going.aspx

Please Note: Even though this was written with Fallout 3 in mind, it also works for Fallout New Vegas. Enjoy!

The game engine has some issues with processors that have more than 2 cores. You can force the game to only use two of them and it will stop the freezing. I haven't had it freeze once since I did this several days ago.

Open up the fallout.ini file in: My DocumentsMy GamesFallout3

(Note: In Fallout New Vegas, Most tweaks which would normally go in the Fallout.ini file in Fallout 3 actually need to be made in the Fallout_default.ini file found under the Program Files (x86)Steamsteamappscommonfallout new vegas directory in Fallout: New Vegas. This is because when the game is launched via Steam, it opens the launcher first, which overwrites your Fallout.ini file with the contents of the Fallout_default.ini file, along with your launcher settings. Make a backup of Fallout_default.ini, then edit it with a text editor.) (Source)

Find the line:

bUseThreadedAI=0

change it to:

bUseThreadedAI=1

Add another line after it and insert:

iNumHWThreads=2

This will limit the game to 2 cores and prevent the engine bug from causing the game to freeze.

From the PC Gaming Wiki's 'Fallout New Vegas - Game Crashes Randomly' article:

D3D9.dll Replacement

• Start the installer in compatibility mode for Windows XP SP3 and as an Administrator.
• Download D3D9.dll from MediaFire or a similar source.
• Place D3D9.dll in the directory that contains FalloutNV.exe.

Random Crashes (Random Crashes that tell you FalloutNV.exe has stopped working.)

• Download the following mods: NV Stutter Remover, CASM, Fake Fullscreen Mode Windowed.
• For assistance on downloading these mods: http://www.youtube.com/playlist?list=PL0E5E8CA384409B11&feature=plcp

I have personally tried NV Stutter Remover and CASM. NV Stutter Remover modifies the game to be more 'stable' (more info on its New Vegas Nexus page here). CASM (Cipscis' Automatic Save Manager) allows for an incremental auto-save function specified by a time preset (can also be done manually through a hotkey), allowing you to load a savegame close to when FNV crashed. Fake Fullscreen Mode Windowed runs the game in windowed mode, which some report as helpful in preventing crashes (more info in its New Vegas Nexus page here).
