(Solved) RenderMeshSystemV2: Huge spike every 10 seconds after updating to 2019.1

Hello! I've just tried updating my game from 2018.3 to 2019.1.10, and am having some issues:

I'm getting a massive spike every 10 seconds or so:


Note that this is only in the editor, but regardless it makes testing extremely frustrating. I also noticed I'm getting massive physics (Physics.Processing) spikes after updating, I figured it was irrelevant to this issue, but I've also noticed they often (but not always!!) go hand in hand (RenderMeshSystemV2 spike, then the next frame the physics spike).

Any thoughts?

 

Just kidding, I'm an idiot - when I updated to 2019.1, I didn't update the hybrid renderer package. This seemed to do the trick! I also updated the probuilder package at the same time, so it's possible it was either one of those.

However, the physics spike does still happen, but that is for another thread discussion
