Uncooking is something you need to do for most unreal engine games using directx,it is hard to do and requires advanced pc users(im not advanced)
I'm pretty sure if that was the case the devs would say that on the webpage. I'm learning development for Unreal Engine and I've never heard of "uncooking" before.
Uncooking exists,and most devs dont say they're game needs you to do it
