Quietly optimized

Why Quietly optmized? (Qo)

Quietly Optimized (Otherwise just QO) is your go to performance modpack. One of the originals performance modpacks on Modrinth with a rich history.
Pushing minecraft to its very limits.

Performance increases (Up to 500% over vanilla)

Network stability improvements (Makes playing on servers way more stable)

And many quality of life mods to improve your gameplay.

Speeds up loading times (By a lot for my system)

World loading time decreases

Other micro optimizations

Frequent updates! (Make sure to follow so you never miss them)

Updated rendering engine (OpenGL 4.0+ courtesy of GPUBooster)

My recommended launchers

ATLauncher - One of the BEST launchers you can use.
https://atlauncher.com/

MultiMC - Rock solid launcher for those who want a more stable experience.
https://multimc.org/

Modrinth's app. The official Modrinth launcher. Its pretty solid. And open source.

NOT RECOMMENDED LAUNCHERS

Prism Launcher - Hostile fork of PolyMC, current owners tired to force the old repo owner out.

PolyMC - Pretty much dead, you're better off using MultiMC or ATLauncher.

Quilt information -
While this modpack technically unofficially supports quilt, it is not recommended for three main reasons.

1 : The projects goal is to remove fabric support entirely, thus splitting the modding scene further. Though they have wiped this off their website, I still have a feeling that this is the underlying goal.

2 : Generally a useless fork of fabric, which was created from drama that was so petty it could've been resolved privately.
