OptiPrime is a pre-configured client modpack built to reduce RAM consumption and increase framerates (FPS). It functions as an open-source alternative to OptiFine.

Functional Features

  • Pre-assembled: A ready-to-use mod list. Requires no manual searching or testing of individual mods.
  • Resource Management: Lowers memory allocation and stabilizes frametimes across different hardware setups.
  • Open-Source Base: Compiled entirely from open-source projects, ensuring technical transparency and rapid updates.
  • Multi-Loader Support: Actively maintained for NeoForge, Fabric, Forge, and Quilt.

Technical Foundation

Performance is achieved through a specific set of mods (exact list varies by loader and game version):

  • Rendering: Sodium / Embeddium alters chunk rendering logic to increase FPS.
  • Memory: FerriteCore and ModernFix reduce RAM usage and patch vanilla memory leaks.
  • Culling: EntityCulling and MoreCulling skip the rendering of unseen entities and blocks to save CPU cycles.
  • Shaders: Iris / Oculus provide native compatibility for shader packs.
