FPSMaxx 1.3.0

FPSMaxx 1.3.0

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 - applies Fast graphics, clouds
  off, cloud distance 2, minimal particles, render 16, simulation 8 and
  a 60 FPS target.
• Potato preset - goes to render 8, simulation 5,
  tiny cull distances and a 24-section update budget.
• Adaptive chunk-section culling - chunks stay loaded, but only the
  affordable visible radius is submitted to the renderer.
• Chunk-update budgeting - caps mesh rebuilds per frame and re-queues
  the rest, smoothing stutter.
• Particle culling and budgeting - rejects and removes 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; low-end lowers it to 8 and potato
lowers it to 5.
