FPSMaxx 1.5.0

FPSMaxx 1.5.0

FPSMaxx is a client-side optimization mod for Minecraft 26.3 with
Fabric and NeoForge builds. It is built for smooth gameplay on
low-end PCs while keeping high-end machines fast.

Choose your jar

• Fabric 26.3: FPSMaxx-1.5.0-fabric-mc26.3.jar
• NeoForge 26.3: FPSMaxx-1.5.0-neoforge-mc26.3.jar
• Fabric 26.2: use the previous 1.4.1 release.

Fabric users also need Fabric API 0.165.0+26.3 (or newer for 26.3).
NeoForge users need NeoForge 26.3.0.97+. Java 25 is required.

How it optimizes

• Hidden FpsMaxx preset - drag the Graphics Preset slider all the way
  left. The FpsMaxx position applies the adaptive governor, all cull
  distances, the particle budget and the chunk-update budget together
  with the low-end graphics reductions.
• Low-end preset - /fpsmaxx lowend applies Fast graphics, clouds
  off, cloud distance 2, minimal particles, render 16, simulation 8 and
  a 60 FPS target.
• Potato preset - /fpsmaxx potato 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, and adds a searchable
  FPSMaxx page with an Open FPSMaxx preset screen button to Sodium's
  Video Settings.
• Fresh & Smooth aware - auto-detects the pack and keeps its shaders,
  particles and animations with a visual-safe profile.
• Particle optimizer aware - defers particle culling to AsyncParticles
  or Particle Core when installed.
• 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.

Loader notes

• Fabric: Sodium 0.9.2+ for 26.3 works. The jar also runs on Quilt.
• NeoForge: use Sodium NeoForge 0.9.3-beta.1+ for 26.3. Sodium
  NeoForge 0.9.2 has a broken LevelExtractor mixin on 26.3.
• PojavLauncher / MojoLauncher: use the Fabric jar. NeoForge is not
  supported by most mobile launchers yet.

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.
