It’s honestly baffling how inefficient the entire vanilla engine is. They’ve fixed up the lighting engine in 1.20 at the very least,so that annoyance is gone, but still… the fact that a few part time freelance devs can whoop mojang’s ass (who pays like 100 developers for java) in every other optimization category is just baffling. What the fuck does mojang pay all those people to do on java? It took them a decade to fix the clusterfuck of an inefficient lighting engine.
