If you're the sort of person who's deep in the throes of EXAPUNKS, you should be aware that 7 Billion Humans was released today, and it will fill a very similar void in your life. Think Human Resource Machine + SIMD. https://store.steampowered.com/app/792100/7_Billion_Humans/
Obligatory introduction tüt! Hello, I'm Cort, (postgoodism, elsewhere), and I work at Unity Burbank on the engine's "performance by default" initiative (see also: ECS, JobSystem, Burst, etc.) Someday soon, I hope to be able to offer useful assistance regarding Unity optimization, but right now I can virtually guarantee that you know more about the engine than I do.
Now: Unity (DOTS, ECS)
Before: Google (Vulkan, Stadia, VR)
Beforer: Sony (ICE Team, Gnm, EdgeGeom, SPUs)
Beforerer: Maxis (junior stuff)
