i am sorry but there is a deep misconception here. of course you can update thousands of things, why wouldn't you.

try racing game for instance: https://twitter.com/0xca0a/status/1400164834243719173

or space game: https://twitter.com/0xca0a/status/1184586883520761856

you won't find react in the browsers perf readout except for short blips when the tree structure is changed. you do not update fast things with setState. since games are render-loop driven, you mutate, and that is also how r3f works.

as for react 18, yes, it works global. the entire component tree is virtual and can be prioritized. you could say, this thing back there is less important than physics driving my rocket, defer please. this will be an incredible tool for games going forward.
