It’s not uploading the same for pc and quest, its about just the names of the ranking system. Most things would remain the exact same, the only things that would need to be altered that I can see would be “Particle Trails Enabled” and “Particle Collision Enabled”.
It would many be a visual change, nothing that would effect much uploading.
You can see the difference on the performance ranks page they have : Performance Ranks | VRChat Creation
(The ONLY downside is the fact quest users would no longer be able to view Very poor avis, but VRC has already been considering this for a while, however the system vrc has been considering is blocking Very poor(quest) not very poor(PC), which would make quest users not see 90% of avis on vrc. I’ve spoke with other creator friends, and they all say if they wanna do that, it should block very poor(pc); HOWEVER, quest users cant tell the difference between Poor(PC) and Very poor(PC), so there wouldn’t be any good way of implementing that.
However, if it was a global system like this, then they could easily do that without completely messing up creators and quest users because of the strict limitations on quests.
I hope that helps to explain it better! ^o^
