Nanite displacement/tessalation not working in Unreal Engine 5.3 update

no one seems to know. or want to know
how can this be missed by so many users?

is it only AMD users?

this is dumb and consuming way more time than it should

DOES IT WORK

NO

when it does work. its either preset on a asset like “rural australia” megascan.
and the value is. 0 or 1. on or off. no scale no other changes.
and if u try to use lumen for GI even on an empty project i get crash out of memory after 20-60 seconds. BLANK PROJECT!
