How To Optimize Your Unity Game With CullingGroups
Taking a look at the CullingGroup API and one potential use case of spawning enemies at various points in a level.
I had originally recorded an actual deep dive, going through all of the documentation on the Unity website, but it didn't really add much to the video though I encourage you to read it on your own.
There is plenty more that could be done to optimize and make this system better, but I wanted to focus on just setting up the CullingGroup. I also forgot to Dispose the CullingGroup in OnDestroy, be sure to do that!
Profiling - Before - After:
Total - 23ms - 5ms
