FPS plummits around ritual, harvest, delirium.

I don't even have to start the ritual. Just standing next to it kills my game play.

Processor Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz 4.20 GHz
Installed RAM 16.0 GB (15.9 GB usable)
System type 64-bit operating system, x64-based processor

NVIDIA Geforce GTX 1080 ti.

Sure she's getting old, but I don't recall interacting with these league mechanics being like this in previous leagues. I've adjusted setting until I'm blue in the face. I don't mind playing on lower graphical settings if that'll fix it.

Thanks
