FNV 4GB Patcher makes your Fallout New Vegas game believe that your system has 4 GB of RAM installed, even if it doesn't. When present and installed correctly, it will auto-load NVSE during the initial startup. If you use several mods and want to improve speed and performance, this mod will help you achieve just that.

If you use multiple enhancement packs, such as New California mod for Fallout New Vegas with Fallout New Vegas Stability Enhancer and Stutter Remover, using 4 GB of RAM will tremendously improve your gaming experience and help make the game run correctly. It will also help if you run graphical enhancements or texture pack mods.

Does it work with NVSE?

The FNV patcher does work with NVSE. The mod aims to fool your game into thinking your system is running 4 GB of RAM. It's a great way to get around the restrictive 2 GB requirement.

Does it have restrictions?

This mod only makes your computer falsely aware of 4 GB of RAM. Gameplay will still struggle with this mod if you lack a 64-bit OS, sufficient RAM, and a quality CPU with a dedicated graphics card.

Does GOG have 4 GB of RAM?

Yes, it does. Still, this mod is relevant because it makes GOG load NVSE automatically. So by simplifying the launching process, the mod makes startups quicker and easier.

Adaptable for modern platforms

This Fallout New Vegas utility mod works with Steam and GOG versions. Unfortunately, XBOX Game Pass and Bethesda versions are not supported since neither system supports NVSE.

Fuss-free launching

Helping eliminate driver detection problems and working with most default launchers is fine. However, you will still need Visual C++ 2013 Runtime to run this mod, even if you own a legitimate version of the Fallout New Vegas game. This factor is one of the main downsides.
