Similar to age gated instances, you could create a higher tick rate instance for everything, udon, avatar ik (face tracking, contacts), string, and others, only with VRC+

Could even just be a doubled increase, 22/tps instead, and could be limited to only vrc+ users who could join, or limited to only PC if quest couldn't handle the update rate.

this would help game worlds immensely like first person shooter PVP as you get the "shot while behind a wall" situation way too often, while still keeping the option for 11 tick rate/update rate for other games like idle games or cookie clicker-likes.

could even limit the instance creation to only worlds which VRC has an approved 'Game' tag, so that only game worlds that would benefit or need a higher tick rate can have those instances, and then vrc wouldn't have to dedicate as many servers to the less used, but still appreciated higher tick rates.
