I found that displacement runs super slow in v6, this is bit weird because when the displacement is applied to simple surface @very high it becomes superslow but if i’ll extract render mesh and hide srf with displacement extracted mesh runs super fluidly without any hassle.
I know that on single surface it is bit overkill but: 840560 total triangular polygons
Even more strange: i made array 3x3 with total ~7,5 million poly and still runs fluidly on extracted mesh while 2x2 planes with displacement on killed viewport
