Clumps Mod for Minecraft 1.19.4, 1.19.3, 1.19.2 and 1.19, adds optimization features related to experience orb collection, improving performance.
Now, the experience orbs will be merged into one, eliminating the fps jerks that were caused when many of these orbs were in the same area.
The main goal of Clumps is to improve game performance, allowing players with worse devices to play Minecraft without lag. To do this, the orbs released by the creatures when they die will be combined into a single experience ball.
In fact, it will work the same way with experience bottles or orbs dropped by other related mods. As is logical, these orbs will grant the same experience as in their default form, albeit in a reduced number of orbs.
