LOOT is the Load Order Optimization Tool which tests the integrity of game plugins and files and alerts you of the issue. LOOT is essential for any properly modded New Vegas. So to clarify, install NVSE and then install FNV4GB on top of it, then launch Fallout: New Vegas through NVSE. (You have to have NVSE installed obviously.) Install in the same manner as you installed NVSE and run the now installed patcher to patch your game, and then run the game via NVSE_loader. This is required if you want to run HD texture mods, an ENB or any mod that requires heavier RAM usage. Those 4 gigabytes will serve like a reserve set of RAM. In other words, this means Fallout: New Vegas is allowed to allocate an extra 4GB of space on your hard drive. Then, drag and drop all the files contained into the Main Directory where FalloutNV.exe is located, not into the Data folder. To do this, just open the zip file that NVSE comes in and open the nvse_5_0_beta 3 folder inside. NVSE, unlike Skyrim's version, NVSE does not have an install wizard so you'll have to install it manually. New Vegas Script Extender, or NVSE make sure to install the beta version, 5.1b4 is very important and it is also required by an insane amount of the greatest mods that change the game in a positve way. NVSE, FNV4GB, LOOT, FOMM, NMM, FNVEdit, MCM, and VortexĪll credit goes to developers of the many tools! If however, you need to lauch the game through the defult launcher, set Fallout.ini and FalloutPrefs.ini to read only You'll want to launch the game via NVSE_loader.exe in your New Vegas folder. This will reset your Fallout.ini and FalloutPrefs.ini to their default state, causing a lot of work for you. WARNING: Do NOT EVER, under any circumstances run Fallout: New Vegas through the vanilla launcher on the steam client.
