Engine Performance Regression

Hey all, I just posted a new question/report up on AnswerHub.

In short, I have been seeing a pretty bad in-editor performance regression that causes me to drop frames to around 10 fps or below. Just curious to know if anyone else has been experiencing this over the past couple engine versions. Almost feels like a memory leak, as it doesn’t happen until after working in the engine for a little bit, or making some significant changes to the Content Browser (i.e. deleting assets and running fix up redirectors). Any insight is appreciated!
