Character Inking causing FPS drops

Hi with the new patch I experienced FPS drops from a constant 60 to 30/40. It wasn't until the end of the game that I checked and the problem was that character inking was enabled.

I think character inking should be unchecked by default in case that's a problem for some people that may not know what's causing FPS drops.
