I remember early, soon after the game was announced, there was discussions of unity updates and what they could mean for the game. As far as general improvements, increase in scope, added functions, and so on. Not much of a programmer but I recall discussions of multi-threading rigid body physics, the (im)plausibility of it being possible, mentioning of DOTS and BURST etc.
So instead of either being sad that we have to wait another year and a half at least for the game (oh god so long...) or simply cheering on "we can wait!" / "it's done when it's done"... As a layman I ask the more coding literate among us.. What new possibilities can be considered in bounds now? What future updates would this game have missed that might now be implemented?
