This mod pack is a cut down version of my other mod pack, uPack. This version focuses much more on performance, but still has some QoL features. Suited for low-end devices.
Server Usage:
THIS MOD PACK MAY NOT BE ALLOWED ON SOME SERVERS, DUE TO MODS LIKE "GammaUtils". PLEASE CONSULT WITH STAFF ON THE SERVER YOU'RE TRYING TO PLAY TO SEE IF THESE MODS ARE ALLOWED! I'LL NOT BE RESPONSIBLE FOR ANY BANS HANDED OUT BY USING THIS MODPACK!
Features present:
OptiFine Resource Pack Support
Fast World Quitting
Optimizations ranging from NBT handling to world rendering, and more!
Joining servers with different versions
Singleplayer Server (world) optimization
8-bit resource packs
Extra features for Sodium
Memory Optimizations
Handling Cullings effectively
Reducing FPS when not needed, eg. having the game minimized.
Faster mathematical functions.
Particle improvements.
Detailed Block Viewer
Features Removed: Shader Support. Many QoL mods. Dark Mode. Optimizations that have effects on uncommon elements. Darker Loading Screen. Dynamic Lighting. Voice Chat. Redstone QoL. ... and much more!
As mentioned earlier, devices not being able to run "uPack" smoothly due to it being heavy, should run this one much smoother. Essential QoLs (in my opinion) have stayed in this pack.
As always, please support the developers/creators of the mods and resource packs, not me!
