What in this update broke the fps?

The stutters are very obvious indeed in this update. One thing I noticed very clearly, the drop on the fps due to work that is main thread is doing, possibly loading new orthos. It used to be like this before but the fps drop wasn’t noticable, now is like from 40 to 25 for few seconds and back to 40. Not the annoying micro stutters. Something definitely is ■■■■■■ in this update
