Based on Fabulously Optimized and Simply Optimized, this is a modpack that greatly increases your performance. (Sorry to those who downloaded the first 1.21.5 version, my worlds gave me an error that said "Invalid player data", locking me out of my worlds.)

The video above is how much this modpack optimizes your game.

Why does everybody need ANOTHER optimization modpack?

Because this has 4 pages.

Do I need this?

Well, depends on the PC. My laptop needs it bad. The computer I used in the video doesn't.
