what is this optimization

im pretty sure they fixed the optimization with the newer updates to some degree, but holy hell this game sucks kinda lowkey. my computer recently broke or something, i have no clue, so i had to start playing crk on my ipad (its 4 years old and runs most things fine), and it's literally impossible. i have a bunch of storage on my ipad so i dont think its a storage issue, maybe a memory issue (yet again my pc is a decade old and ran crk practically fine until this update came out), but every time i try and play crk it crashes every minute or two this is actual hell im losing my mind dude

is this just a problem im having or does the optimization still suck
