Olim's Performance
Olim's Performance is a lightweight performance mod focused on improving both client and server performance without changing the way Minecraft is played.
Client-side optimizations help Minecraft use your computer's resources more efficiently, which can lead to higher FPS, fewer stutters, and smoother gameplay, especially in busy areas or when there are lots of entities around.
Server-side optimizations reduce unnecessary processing and help keep server ticks more consistent. This can make servers feel more responsive and help maintain performance when multiple players or lots of activity are happening.
