What does SmartRender Engine add?

⚡ SmartRender - Ultimate Entity Optimization

SmartRender is a lightweight, client-side performance optimization mod designed to dramatically boost your FPS. It targets the heaviest parts of Minecraft's rendering engine—entities, animations, and particles—without altering the game's core visuals.

🚀 Key Features

🔍 Smart Entity Culling: Automatically stops rendering entities (mobs, dropped items, etc.) that are behind your field of view or hidden behind solid walls. Your GPU won't waste power drawing things you can't see!
⏳ Distant Animation Throttling: Lowers the animation frames of mobs and players further than 40 blocks away from 20 FPS to 5 FPS. This significantly reduces high CPU and GPU stress in crowded areas.
💥 Adaptive Particle Filtering: Intelligently reduces redundant cosmetic particles during heavy explosions, potion splash effects, or dragon breath attacks. Visual quality is preserved while preventing sudden lag spikes.

🌐 Compatibility & Safety

Multi-Version Support: Built to run smoothly across all major versions from Minecraft 1.20.1 up to 1.21.1.
100% Client-Side: Does not require the mod to be installed on servers. You can safely join any vanilla, Aternos, or large multiplayer economy/PvP server.
Anti-Cheat Safe: This mod only affects how things are rendered on your personal screen. It sends absolutely zero packets to the server network, making it fully undetectable and safe from bans (GrimAC, Vulcan, etc.).
Modpack Ready: Works standalone without requiring Fabric API and coexists perfectly alongside popular performance mods like Sodium, Lithium, and Iris Shaders.
