None of the information online really helps with the memory leak except adding -nomoviestartup which removes all the cutscenes in the game. From what I can tell the real problem with the memory leak is the loading screen "cutscenes".

So for this fix all you have to do is navigate to
BorderlandsGOTYEnhanced\WillowGame\Movies
and delete (or move) all the ones that say "loading".

This is only for the main game, if you want to remove them from dlcs, youll have to go to each movies folder in each dlc located in
BorderlandsGOTYEnhanced\WillowGame\DLC\Shared
and delete each loading movie from there as well.


This will make it so you have cutscenes still, but all the loading screens will be black. A pretty good compromise I think.
