⁉️ Why Optimus?
🔥 Blazing fast performance
Optimus is based on Adrenaline, onme of the greatest performance packs available. It greatlty improves minecraft's performance by default, and Optimus goes further to add a few mods not bundled by default
📦 Everything you need is already prepackaged
Just install and go! Optimus provides a great lenght of QoL client-side tweaks, whilst keeping maximum performance.
🧡 Made with love.
Optimus is a passion project, born long before the first public release. I've been building performance modpacks for 7 years (due to tremendous need lol), and Optimus itself was born 3 years ago.
✒️ Good design.
Come on, don't you love the orange arrows?!
❔ Why not just use OptiFine?
OptiFine's methods are and have always been extremaly invasive. This leads to a lot of issues with other mods, and also slows down updates. Also, it doesn't offer the same boost in performance today as it did on older versions, when it was at it's peak.
