MacOS massive spike in RAM usage and InitViews when converting a project from 5.5 to 5.7.

I’m seeing a massive spike in RAM usage and InitViews when simply converting a project from 5.5 to 5.7.
Basically it goes from being playable (40-60fps) to completely unplayable (4-30fps).

I’m wondering if anyone out there has any advice of what to look for to track this down?

It seems like something under the hood in 5.7 is automatically causing this spike. I know InitView has something to do with view culling but there’s nothing special about the culling I’m doing.
I dont’ imagine it’s Draw Call related as there are very few of them.

An update for the historical record…

I tried debugging the issue using Insights but I couldn’t find any clear cut indicator of what is causing it. I tried process of elimination…literally removing every element in the project. Nothing worked so I did a series of tests using the stock 3rd Person template and saw the same issue. I then submitted a bug report.

Including images of my testing…
