The Optium is a performance-focused optimization pack built on the Fabric loader. It helps improve game performance and stability without changing vanilla mechanics or adding new gameplay content.
Rendering Engine Overhaul: Reworks the graphics engine to boost FPS and cut down on micro-stutters while exploring.
Memory Management: Lowers RAM usage, improves garbage collection, and speeds up client startup times.
Physics & Logic Streamlining: Optimizes background processes like entity pathfinding, chunk generation, and internal server ticks.
Visual Quality of Life: Brings back features like custom shader support, dynamic lighting, connected block textures, and camera zoom.
Network Stability: Improves packet handling to reduce latency and keep multiplayer connections more stable.
The pack works as a drop-in replacement for the standard client and is fully compatible with vanilla servers and Realms.

This modpack runs on Fabric and NeoForge for Minecraft 26.x. The launcher you install it with sets that up for you.
Download the .mrpack file from Modrinth.
Open it with a launcher that reads .mrpack files, such as the Modrinth App or Prism Launcher: it makes a new instance with every mod and setting of the pack.
Give the instance enough memory: most modpacks want 4 to 8 GB.
To play it with friends on a server, use the server files of the modpack if its page offers them; otherwise install the same mods on the server.
