Yea but what I mean is that serve meshing ain't done yet and far from it as well as many of the game mechanics especially in fps mode/view
Did you half finish your reply? That sentence appears incomplete. Server meshing directly is needed for player increase whilst also expanding the player area. The first step though is SSOCS which is being worked on accordingly to the devs. In which case there shouldn't be a reason to not add in game mechanics.
Server side meshing is really only going to be critical to get beyond the single system & 50 player cap we have. Which likely wont be till 2022 in my honest view. Then we will likely see more systems and increased player cap. I don't think we will ever get past a limited number though rather there will still be instancing needed in my view.
Vulkan is meant to happen at some point but I can't see that happening till after SQ42 either tbh and so the first episode of SQ42 will be DX11.
Edit:
what has fps mode/view got to do with game mechanics and server meshing?
