As a game developer, I don’t think this is particularly noteworthy.

I’m sure it was a very important optimisation for Star Citizen, but it’s not like some amazing tech that will be important for the game industry or anything.

Star Citizen had some awful performance problems, and because the development is quite public, optimisations that programmers are working on get important sounding names and publicity all their own. If it wasn’t for that, this would just be an implementation detail in their engine.
