A way to disable baron/dragon vfx?

I have a potato pc, and i can hardly get 20 fps in team fights. Problem is when a team gets baron or dragon. At that moment i have 5 fps. It would be a very good thing if you could disable baron vfx on minions and dragon vfx on champions. You already know they took it. There's no reason to show it in your face and make you lose fps..
