FalloutNV:FNV 4GB Patcher
FNV 4GB Patcherby LuthienAnarion, Roy Batty
Guide/Version-Specific Mod Recommendations
Even though the GOG version of Fallout New Vegas is pre-patched to make the FNVPatch.exe executable able to use up to 4GB RAM, this guide still requires users to install the FNV 4GB Patcher from Nexus regardless, as it has a built-in compatibility with NVSE and shaders like SweetFX and Reshade.
- Download the latest version. Choose manual download from the download tab at Nexus.
- Place the FNVPatch.exe file into
Fallout New Vegas\(not the data directory!), usually found at
...\Steam\steamapps\common\Fallout New Vegas.
- Run FNVPatch.exe.
Use MO to call the game executable, not "NVSE" or the launcher. The game is now "patched" to see 4GB of memory and will automatically load NVSE if present.
