Hey Epic, I noticed while eating my sandwich today that in the editor I get sudden drops in performance if I let it run for 10-20 seconds.

I did a bit of research here at the office, and it looks like this isn’t happening in our internal build, but I was able to reproduce it in 4.3. I’m not sure what’s causing it - maybe something related to the way the objects in the level are loaded in? Anyway, that means that the bug should be fixe…
