⚡ OptiElitePlusz (v1.3.1)

📢 IMPORTANT PROJECT NOTICE:

OptiMobilePlusz has officially been rebranded to OptiElitePlusz starting from v1.3.1! Along with the new name, this update officially introduces deep, native optimizations for low-end desktop PCs and laptops, while remaining 100% committed to providing the ultimate performance boost for mobile players.

🚀 The Elite Performance Engine for Low-End PCs, Laptops & ARM Mobile Devices

OptiElitePlusz is a high-performance optimization mod for Minecraft 1.21.1 (Fabric). It is specifically engineered to maximize FPS, eliminate micro-stutters, and guarantee thermal stability on weak, budget, or older hardware—ranging from low-spec desktop PCs to mobile systems running through PojavLauncher or Zalith Launcher 2.

By utilizing advanced Fabric client hooks, lightweight runtime modules, and dynamic GUI-driven profiles, the mod auto-tunes your game engine on the fly. No complex manual tweaking required—just raw, optimized performance.

📊 Performance & Hardware Profile

Target Hardware: Low-spec Desktop PCs, older Laptops (integrated GPUs), Snapdragon / ARM-based Android setups, and low-power handhelds.
The Result: Massive and stable FPS gains through adaptive thread throttling, intelligent chunk prioritisation, advanced entity culling, dynamic LOD scaling, and streamlined rendering pipelines.
Best Used For: Low-end desktop setups, memory-constrained environments, mobile-first play, and heavy modpacks where frame stability matters more than unoptimized visual fidelity.

📈 Real-Time In-Game Benchmarks (No other optimization mods used!)

OptiElitePlusz 234 FPS Benchmark Over 230+ FPS achieved purely with OptiElitePlusz on a mid-range mobile device (Snapdragon 695) in a dense forest biome—with zero other optimization mods installed.

OptiElitePlusz F3 Diagnostics Extreme memory efficiency and zero lag spikes: running Minecraft 1.21.1 Java Edition smoothly while allocating only ~526MB of RAM (25% footprint).

🚀 Key Features and Improvements

🎛 Adaptive Performance Engine (PC & Mobile)

Adaptive Engine: Automatically switches between EXTREME, PERFORMANCE, BALANCED, and ULTRA profiles based on your live, real-time FPS.
Frame Budget Manager: Dynamically triggers during heavy lag spikes, reducing expensive rendering workloads to keep your frame times consistent.
Architecture Detector (NEW v1.3.1): Intelligently detects whether the game is running on a standard x86 Desktop PC or an ARM Mobile platform, automatically applying tailored system thread and garbage collection parameters for that specific hardware type.

🧠 Advanced Rendering & World Optimization

Smart Entity Culling: Dynamically hides distant entities to heavily reduce CPU and GPU overhead on both desktop and mobile screens.
LOD Manager: Scales entity rendering distances down seamlessly during intensive gameplay or weak FPS periods.
Render Throttle: Automatically manages non-essential visual effects and view bobbing to keep your hardware running cool and fast.
Scene Simplifier: Switches complex graphical behaviors to a lightweight, resource-friendly profile when under heavy stress.
Texture Streaming: Throttles asynchronous texture loading to prevent performance drops during rapid world exploration or high-speed chunk loading.
Particle Limiter: Intelligently drops particle counts based on your active performance state.

📦 Chunk, Audio, and Background Handling

Adaptive Chunk Loading: Dynamically alters chunk simulation behavior based on player movement and hardware capabilities.
Background Tick Throttler: Skips heavy background world processing when the game loses focus, is minimized, or when switching tabs on a PC.
Sound Budget Manager: Allocates and limits non-essential audio processing threads to free up critical CPU cores.
Thermal & Lag Protection: Provides soft warnings when your hardware enters a heavy throttling or high-heat zone.

🎮 Enhanced UI & Universal UX Features

High-Performance Smooth Zoom: Built-in smooth camera zoom via hotkey (Default: C). Fully optimized for both desktop mouse precision and mobile touch controls—completely eliminating the need for extra zoom mods!
Pixel-Style FPS Counter: A clean, color-coded FPS display tailored for high visibility on any monitor or screen size.
Detailed Performance Overlay: Real-time diagnostics showing your active budget state, particle multipliers, and live runtime performance hints.
Preset Manager: Quickly cycle through battery/power-saver, balanced, and competition profiles via an intuitive in-game interface.
Config GUI: Toggle and tweak every single feature easily without ever touching a config file.

🛠 Installation

Install Fabric Loader for Minecraft 1.21.1 and ensure Java 21 (or higher) is active.
Download the latest -RELEASE.jar file.
Drop the file directly into your mods folder.
Launch the game and configure your presets using the in-game options menu.

🎮 Recommended Controls and Presets

Zoom Hotkey: C
FPS Overlay: Enabled by default (can be toggled in the config GUI).
Presets:
- battery / power-saver → Maximum hardware stability, aggressive culling, background throttling, lowest resource usage. Perfect for phones and laptops on battery power.
- balanced → The recommended safe default for standard, smooth gameplay.
- competition → High-performance tuning with active hardware telemetry enabled.

📁 Runtime Data & Footprint

All configuration profiles are securely saved directly into the standard Fabric config directory.
Presets and optimization snapshots are cached locally for lightning-fast game loading.
The mod maintains an extremely lightweight memory footprint, making it fully compatible with other standard optimization mods.
