Fallout 4 and 76 both use this engine and its a terrible out dated engine. Then Skyrim used what is called the Creation engine, which was based off of Gamebryo which was based off NetImmersive. Which then became the Gamebryo engine for Oblivion, Fallout 3, NV. The game is on an old ass engine dating back to Morrowind on the NetImmersive engine. But it makes the game look so much better. You will get a performance hit and you will need to follow the steps to install properly. These are just some fixes and performance tweaks to get a better overall experience. Shame, I would still keep this patch though it fixes an insane amount of bugs and is still being updated.įallout 4 Script Extender (must have for most mods)
