Pureformance

Pureformance

Pureformance is a lightweight client-side performance optimization mod for Minecraft 26.2, designed to reduce unnecessary rendering work, memory usage and runtime allocations while preserving visual correctness and compatibility with modern rendering mods.

Rather than focusing on a single optimization, Pureformance combines several rendering, culling and memory improvements into one carefully integrated mod.

🚀 Main Features

• Adaptive Entity Culling
  Avoids rendering entities that cannot actually be seen, using visibility caching and conservative occlusion checks to reduce rendering overhead without introducing noticeable pop-in.
• Block Entity Culling
  Skips unnecessary Block Entity rendering while preserving special render bounds for objects such as banners and other non-standard renderers.
• Direct Frustum Rejection
  Quickly rejects objects that are completely outside the camera view before more expensive rendering work begins.
• Visibility & Occlusion Caches
  Reuses recent visibility results to avoid performing the same calculations every frame.
• Adaptive Tick Culling
  Reduces unnecessary client-side processing for objects that do not currently require full update frequency.
• Render Engine Optimizations
  Removes redundant rendering operations, reduces state changes and improves several frequently executed rendering paths.
• Render-State Pooling
  Reuses temporary render objects where safe, reducing garbage creation and pressure on the Java garbage collector.
• Memory Engine
  Deduplicates frequently repeated Minecraft data such as BlockState collision shapes and face-sturdy information.
• Reduced Runtime Allocations
  Optimizes several high-frequency rendering paths to decrease short-lived object creation.
• Text Optimizations
  Reduces unnecessary work during text and sign rendering.
• Particle Optimizations
  Improves processing of particle-heavy scenes.
• Fluid Rebuild Prioritization
  Improves chunk rebuild scheduling around fluid rendering.
• Map Atlas Optimizations
  Uses a more efficient map texture atlas system to reduce unnecessary texture operations.

⚡ Designed to Work With Your Performance Stack

Pureformance is designed to complement modern Minecraft optimization setups and has been tested with:

• Sodium
• Iris
• Fabric
• Quilt
• NeoForge

On Fabric and Quilt, Pureformance can also complement Item Frame Cache, another optimization mod by the same developer. When both mods are installed, Pureformance automatically avoids overlapping Item Frame optimizations where necessary.

🧠 Conservative by Design

Performance optimizations should not come at the cost of broken rendering.

Pureformance uses conservative visibility checks, caching thresholds and fail-open behavior. If an optimization cannot safely determine that something should be skipped, Minecraft is allowed to render it normally.

This approach helps reduce visual glitches while still removing a significant amount of unnecessary client-side work.

💻 Client-Side Only

Pureformance runs entirely on the client.

Servers do not need Pureformance installed, making it suitable for:

• Single-player
• Multiplayer servers
• Vanilla-compatible servers
• Modded client setups

🔧 Configuration

Pureformance includes configurable optimization systems for advanced users who want to fine-tune culling distances, cache sizes, visibility timing, ray budgets and other performance parameters.

The default configuration is designed to provide a good balance between performance, compatibility and visual stability without requiring manual configuration.

🎯 Goal

Pureformance aims to provide a single, lightweight optimization layer that reduces rendering overhead, memory usage and unnecessary allocations while remaining compatible with the rest of your Minecraft performance stack.

Install it, leave the default configuration enabled, and let Pureformance quietly remove work that Minecraft does not need to perform.
