Hideout FPS drops/crashes

Hi,

first the specs

PC Specs:
Intel 13900k
64GB RAM
NVidia 4080

now my problem
there is some FPS problem with the amount of mtx on mannequins in my hideout. i have arround 20-30 mannequins with all kinds of mtx equipt in my hideout but there are soo much things to load that the cpu lag is so bad that my frames drop into the dirt.

i moved all the mannequins to the bottom of the hideout. when i stand in the top half of my hideout i have arround 150 FPS with 4-6ms CPU and 2ms GPU times.
if i move to the bottom half where all the mannequins are i drop to arround 9 FPS with 100-150ms CPU and 20-30ms GPU times.

a friend with a different CPU and GPU has very similar results. i tried different renderer but that changed nothing, well i'm CPU bound so no wonder.

i tried it with different combinations of the mannequins to see if a specific mtx cause the issue but no. as far as i can tell it has something to do with the ammount of stuff the game has to load/buffer.

i hope my explanation was somewhat usefull. let me know if you need further informations

cheers
