is this some kind of optimization because using 
idiv is too bad?
add(10/5, 10/5, 3/5) 
the proposal for adding one was in 2021 with no activity. gamedev just don't use debuggers huh.

@Learath2 i think i have a faulty usb port (port 6), and it slows down my boot time massively, do u know if its possible to disable this specific port? is this some kind of optimization because using idiv is too bad? [ 3.364712] usb 3-6: new high-speed USB device number 5 using xhci_hcd

big texture chokes slow mem bandwidth. it's just a snapdragon thing big texture chokes slow mem bandwidth. it's just a snapdragon thing 
i also tried secondary details, sampling a repeated texture and splat them onto the model, but the additional sample also tanks the framerate.
probably could hand write the whole thing and save a lot
gamedevs care none of that
that's just a china thing
i did
we do post processing in material shader too
