Since season 6 launch I see a couple of huge glowing areas to the left of the mirror universe map, if I go anywhere near them my framerate drops to 5fps as my graphics card gets bloomed to death!
I just feel that those effects are a pointless addition to the map and if they are staying they need optimising.
And before you say it I know I can just stay clear of them but curiosity got the better of me

I run the game at all max settings and normally dont see framerate drops.

It's not a bloom settings issue, and it's not limited only to the Mirror Universe event.
