tufts is a simple but very useful mod if you experience LAG when a certain number of experience orbs are collected in a certain area. With this mod installed, instead of generating dozens of experience orbs, a single entity will be generated, which will be picked up by the character when we touch it.
Another interesting feature, which is a consequence of generating a single experience orb, is that we will save ourselves from having dozens of experience orbs spinning around our heads, as happens by flaw in the game.
