There used to be an extension that could unlock up to 6gb of memory for the game, all that while still maintaining the original .exe to run it through... sadly I can't find that anymore, and I don't know where it went, does anyone know ?
I found a few detailed guides on how to renmae the .exe-file for fnv4gb so the trainer would "think" it was running everything as normal, but there is a much easier way now...
NVSE has updated their coding a few times now, and in that process they've made fnv4gb compatible with the normal steam-.exe and NVSE, thus enabling running the trainer with fnv4gb too. Just download NVSE and use the alternate loader from the site of NVSE
