I always get a pretty bad lag spike when enough blood spawns. The spikes happen after the particles have already landed and created a decal, doesn't matter if I look at them or not. I have disabled all addons and tested it with perfopus afterwards, the slowdown persisted and perfopus didn't see what was lagging the game.

Maybe it's just a engine thingy. I just hope it's fixable because the addon is crazy good, and the lag is very annoying
