Metahuman vs daz3d?

Cushion

Hiyo buddies!

im currently working on a projekt which will have many characters (d day landing) for a game in UE5. However im struggling with the metahumans and the need for making Them optimismed. How Well are character/model from daz3d optimized? With 9 metahumans (LOD 3, No hair, eyelashes ect) im running with 50 fps in sim. 
Any idea how many models from Daz I can run in a same sim without Loosing to much performance?
