Opening/ Going Close to Shop Drop FPS

[Cpt_SR]

After opening the shop FPS drop significantly (around 40-50 fps). I am also seeing performance loss quite a lot after the recent update.
I would like to see options to choose shadows to turn off completely or choosing between Sun shadow/All (Like CS2 dynamic shadow Sun/All).

I am really enjoying Deadlock, but this performance issue is hindering my enjoyment. Thank you
