About this Modpack
English
Fastably 1.20.1 is a Minecraft Forge modpack (version 1.20.1) designed with one goal: to boost game performance to the maximum without altering gameplay.
The pack works on any PC where vanilla Minecraft runs at 40-60 FPS. If you have that baseline, Fastably will make your game smoother and more stable.
For multiplayer, the e4mc mod is included so you can easily play with friends. If e4mc causes issues, just disable it and enable World Host instead — one of these mods will work. It’s recommended to try e4mc first.
If you plan to play on servers, disabling Distant Horizons is advised for better stability. This does not apply to single-player worlds or hosting for friends.
Recommended Java launch arguments for best performance:
-XX:+UseZGC -XX:+ZGenerational -XX:-ZUncommit -XX:ZAllocationSpikeTolerance=1.0

Fastably 1.20.1 — это модпак для Minecraft (Forge, версия 1.20.1), созданный с одной целью: максимально поднять производительность игры без изменения геймплея.
Модпак работает на любом компьютере, где ванильный Minecraft запускается с 40-60 FPS. Если у вас такая базовая производительность, Fastably поможет сделать игру плавнее и стабильнее.
Для мультиплеера включён мод e4mc — чтобы вы могли легко играть с друзьями. При этом если e4mc вызывает проблемы, просто отключите его и включите World Host — один из этих модов точно будет работать. Рекомендуется сначала пробовать с e4mc.
Если собираетесь играть на серверах, лучше отключить Distant Horizons для большей стабильности. Это не касается одиночного мира и хостинга для друзей.
