I just got a new pc going from intergrated i7-6700 graphics to 5950x and 3080. Wanting to keep all my apps and everything I cloned my c drive to a new 1tb nvme but unreal seems to think i am using my old pc as i cant use shader model 6 and i cant use nanite cause my graphics hardware doesnt support it. I’m reinstalling ue5 but my internet connection is slow so im posting this in case that wont work.
maybe turn off the onboard gfx in bios and be sure to have latest nvidia drivers installed
or install windows fresh
you can reinstall windows without changing your files and progs using the recovery mode
but
if that doesn’t work
sometimes starting from squeeky clean is what your prod env needs.
