Regression

Yes

Culling performance regression when spawning a large amount of primitive models

Graphics - General

-

How to reproduce:
1. Open the "SampleScene" Scene in the attached "1217274.zip" project
2. Open the Profiler window
3. Ensure that Module details panel is set to Timeline
4. Enter Play Mode
5. Exit Play Mode after getting a "Finished Benchmarking" message in the Console window
6. Observe the Culling performance in the Timeline Module

Expected result: The time that it takes for culling stays relatively the same or lower throughout versions
Actual result: The time that it takes for culling has increased by an average of 3 ms

    If you create a standalone build with the supplied project you can easily see the performance drop, even if you go as far down as 50000 cubes (then there's a performance regression of around ~0.6-0.7ms). It's not easy to see the difference with anything lower than that.

    Also, if the editor freezes now, but didn't freeze before, perhaps that is something else that should be looked into?
