(Please Help) Metahuman Problem

So for some reason when I use a metahuman for my game and when i play around in it in the editor it gets laggy when I look at the metahuman. I’ve tried turning down the lodsync numbers and lowering textures quality but when I do that most of the lag stops but sometimes it will have a lag spike. so I don’t know what to do and i have a good pc so i don’t know why it’s doing this (Please Help)
