FPSMaxx 1.2.0

FPSMaxx 1.2.0 - low-end optimization

FPSMaxx is a client-side Fabric optimization mod for Minecraft 26.2, built for smooth gameplay on low-end PCs. It unlocks a 64-chunk render distance and uses an adaptive visible-radius governor to protect frame rate.

How it optimizes

• Low-end preset - /fpsmaxx lowend applies Fast graphics, clouds off, minimal particles, no entity shadows or smooth lighting, render 16, simulation 8, a 60 FPS target and a 60 FPS cap.
• Adaptive chunk-section culling - chunks stay loaded, but only the affordable visible radius is submitted to the renderer.
• Particle culling and budgeting - rejects distant particles and shrinks the live cap when FPS falls.
• Sodium integration - caps Sodium's terrain search distance and fog to the same radius without unloading chunks.
• Entity and block-entity culling - skips distant entities before extraction and submission.
• Memory guard - prevents small heaps from loading more chunks than they can safely hold.
• Chunk retention - visible mode avoids repeated load/unload stutter.

It is a rendering optimization mod, not a mob-AI or server optimizer. Simulation distance 32 is CPU-heavy; the low-end preset lowers it to 8.
