I posted in the discussion for the mod in an attempt to get some more info about the mod. As I noted there, I'm no expert. But I've done some coding before. What is being said about persistent markers building up in the database over time seems dubious to me... it shouldn't build up like that if you remain in one cell. They should build up in every new cell you travel to, if I'm not mistaken. Also, I still see no evidence of a memory leak, and these nebulous other elements being attributed to collision markers don't make any sense to me. Collision markers do nothing aside from acting as objects to collide with. The effect of this mod should be to speed things up in a minor way and to reduce crashes slightly on taxed systems by allowing the game to keep collisions markers in persistent memory, because you only have to to load them on first entering a zone and it won't have to clean them up when you zone out. But the drawback should be that they build up in the database as you zone, making it worse over time and degrading to below vanilla game performance after a number of zones. Even if I'm right (and I'm honestly not sure if I am!) I'm unsure how many zones it would take to degrade any benefit you'd see from the game not having to clean up markers when you zone. Just my thoughts on the whole thing... again, I'm not an expert so I can't be sure. But not everything I'm reading adds up.
