PoE Memory Leak?

Earlier in the dungeons under Caed Nua in the area behind the Drake with all the undead, my FPS dropped from a steady 60 to around 40-50 or so. I fixed it by exiting the game and going back into the game, and it was 60 FPS again. This is usually a sign of a memory leak.

Has anyone else experienced this same exact thing?

(This is the Steam version btw)

By the way....

My inventory is full and my Stash box has tons of items in it. Is this known to lag the game after certain points, etc?

Yeah, nevermind. Its just how the Unity engine is with this game. After a lot of research, combat where magic particles are flying will make high end rigs drop in FPS. Also, Defiance Bay will lag you too.
