🎯 Tips & Tricks
Install NVSE manually by extracting the files into your Fallout: New Vegas root folder (where FalloutNV.exe is located).
Use a mod manager like Vortex or Mod Organizer 2 to handle NVSE and its dependent mods more easily.
After installing, launch the game via the NVSE loader (nvse_loader.exe) to ensure it's active.
