Can there be a change to how global blinds work?

I'm talking about abilities like Nocturne's Ult, Graves and Quinn blinds, (i know theres an obvious official name i just cant remember but yeah). These abilities annihilate the cpu of low-end pcs. My max fps is 36 (rare but achievable in winter with a fan on the pc). This form of cc drops it to 1-3 fps for a few seconds at the end. From best I can tell these abilities despawn then respawn all objects. For a few brief seconds my fps SKYROCKETS to like 60, then the fog ends, and it PLUMMETS down to one to three. There's gotta be a better way to code them.
