Mirage causing fps issues

[OutOfOrder404]

I recently started using mirage and noticed that my fps were dropping by alot, more importantly tho the game felt way less smooth. First I thought it might be due to the immense amount of enemies on screen but after some testing I found out that mirage herself (it doesnt matter if I play mirage or a teammate does) causes these. I made an example video to show what exactly I mean but do keep in mind that the recording itself dumps down my fps a bit, usually I have around 110-120 constant fps on earth with a group of enemies around me without mirage and around 80 with mirage and her 1 active.
