This modpack tries to Optimize Minecraft Fabric 1.21.9/10, nothing more. This Modpack increases FPS a lot. No quality of life Mods, no Zoom, just Vanilla with much more FPS. But of Course you can add some, if you want ;). This Modpack addes nothing special to change Minecraft and it also doesn't have extra features.

Tutorial how to get much FPS: go to Options and then to Video settings. deactivate VSync and change the max Framerate to Unlimited. If you did everything correct, join a world and you should have a lot more FPS now!

extra: if you want the maximum FPS Minecraft gives you, then change the leaves, clouds and weather to fast and the particles to decreased/minimal. these options are in Sodium in the Quality settings.(version 1.0.0 - 2.0.0 2.1.0 I did it for you)
