Toxic Rain performance issues - Night Lotus MTX

Setup

Currently using 2x 6links, consisting of toxic rain and toxic rain ballistas with focus support.

When playing i noticed large fps drops when all totems (5) were down and the TR pods were blooming. After testing in the hideout i've narrowed it down to toxic rains MTX - Night Lotus.

Starting fps ~140 in hideout

No MTX on either TR with totems up

Minor dip in performance but nothing to write home about.

MTX applied to self casting TR - no totems
loss of ~20 fps.

MTX applied to self casting TR - with totems (5)
loss of ~50fps

MTX applied to Ballista totems TR
drop of 80 - 90 fps

This is replicible by turning on/off the MTX on the different TR's. In the worse case scenario, the graph overlay showing fps etc, the white line (sorry don't know what it is) spikes upwards whilst the MTX is attached.

Tested in Vulkan, Dx11 and Dx12 - all the same.

Graphics settings are default with low sun shadow quality and textures set to 4x AF.
