Enhancing Stability: Introducing New Vegas Anti Crash (NVAC)

We’ve all experienced the frustration of Fallout: New Vegas crashing at the most inconvenient times. Fortunately, there might be a solution to alleviate this common issue: New Vegas Anti Crash (NVAC).

NVAC, short for New Vegas Anti Crash, is more than just a mod; it’s an NVSE (New Vegas Script Extender) plugin designed to tackle frequent game crashes. By implementing structured exception handling and sanity checks, NVAC aims to reduce crashes related to access violation exceptions at specific offsets/addresses.

Installation and Verification:

Installing NVAC is a straightforward process. Simply place the nvac.dll file in your Data/NVSE/Plugins folder. Once you’ve run New Vegas, you can verify that NVAC has loaded by checking the nvac.log file located in your New Vegas folder. If nvac.log isn’t present, consult nvse.log for confirmation. Notably, NVAC does not fully support the German “no gore” variant of New Vegas due to development constraints.

It’s important to note that while NVAC strives to enhance stability, it is not a cure-all. The primary focus is on addressing crashes related to access violation exceptions at specific offsets/addresses.

Logging and User Contributions:

Users are encouraged to share exceptions marked with “u” or “v” in the nvac.log file in the comments section. These entries, often the final ones in the log, indicate unhandled exceptions that can lead to crashes. Additionally, users can contribute by submitting “e” or “s” entries for addresses listed as “preliminary” in the readme. This helps in validating addresses to prevent potential crashes.

Bonus Performance Improvement:

Beyond crash prevention, NVAC comes with a bonus feature – it implements helper function inlining. This optimization involves replacing internal New Vegas functions that can fit within a 5-byte space with a 5-byte-or-less instruction, resulting in a minor performance improvement.

Flexible Removal and Compatibility:

NVAC can be removed at any time without affecting your save files. Unlike traditional New Vegas mods, NVAC is an NVSE plugin that modifies the game’s executable code at runtime without making permanent changes. This ensures compatibility and flexibility for users.

Deciphering the nvac.log File:

The nvac.log file provides valuable information about exceptions and their occurrences. Entries include timestamps, codes for various exception types, and details about the exception’s location and code. A guide to deciphering the log file is included to assist users and mod developers in understanding the provided information.

For Mod Developers:

Mod developers are advised to disable NVAC while developing mods to ensure that potential crashes caused by their creations are not suppressed. This can be done via the mod manager or by removing nvac.dll from the Data/NVSE/Plugins folder.

Enhance your New Vegas experience with NVAC, a tool dedicated to minimizing crashes and improving overall game stability. Share your insights in the comments, and let’s collectively contribute to a smoother wasteland journey!
