🚀 Optimally Optimized MC — v1.4 Changelog Tagline: Making Minecraft ASAP (As Smooth As Possible) while keeping it content-ready! This update brings a massive upgrade to visual compatibility without hurting your frames, alongside some under-the-hood engine stability tweaks for lower-end hardware. 🌟 Major Highlights 🎭 Custom Entity Models & Textures are HERE! We have officially integrated ETF and EMF to replace heavy alternative rendering pipelines. This gives you complete, hardware-friendly support for custom resource packs! • Added ETF (Entity Texture Features): Brings full support for emissive, random, and custom entity textures. • Added EMF (Entity Model Features): Enables custom entity models (CEM) and animations. • Why this matters: You can now use popular resource packs (like Fresh Animations) without needing heavy shaders or OptiFine, keeping your open-world FPS high and stable! 🔧 Engine Tweaks & Bug Fixes • New Update (Fast Noise): Fine-tuned world generation optimizations just for your PC. Your CPU will rest even easier when the game is tabbed out or rendering inventory GUIs. • Memory Management: Refreshed Memory Leak Fix configurations to prevent RAM degradation during extended play sessions on SMP or Prison servers. • Cleaned Configs: Optimized the internal layout files. If you are updating manually, make sure to overwrite your old config/ folder to apply the new performance presets! 📦 How to Install / Update (For Offline & SKlauncher Users) If you are using SKlauncher or running a local offline profile, follow these quick steps to apply the v1.4 update smoothly: • Download the updated OptimallyOptimizedMC_v1.4. • In your launcher, click the three dots (⋮) next to your 1.19.2 profile and select Open Installation Directory. • Delete your old mods and config folders. • Extract the new mods and config folders from the v1.4 zip directly into the directory using an MRPACK to zip tool. • Hit Play and enjoy those extra smooth, animated frames with top notch world gen optimizatons!
