Massive framedrop in specific ship

we use a that parks in a POS most of the time, and members use it to do the dailies.

i noticed that one of my toons massively drops framerate when using it, but was just thinking of this unrelated, however i also noticed that other alts of mine have the same issue.
and it always happens when the alts are in the ship to do daily tasks.

the ship is very basic (just reused a old ammo-store ship)

does anyone has the same issue?
the only common thing all the toons have to board this ship, and once they enter warp for the first time the framerate drops below 2fps and stays like this until i log out.

I’ve found that having the Volumetrics Effects even set to low greatly diminishes overall performance. The only (current) way to disable it is to drop your Shader Quality settings to “low”.
