Quick answer

Which OptiCool release should I use?

Updated 1 year ago
Latest stable file OptiCool 1.0 B1
Game version 1.21.5
Loader Fabric 0.16.14

OptiCool 1.0 B1 is a complete pack release for 1.21.5 with Fabric 0.16.14. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 72 mods in this pack file.

Pack setup

How should I set up OptiCool for players and a server?

Use OptiCool 1.0 B1 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

Client instance Install OptiCool 1.0 B1
Dedicated server setup Match OptiCool 1.0 B1
Pack loader Fabric 0.16.14

A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.

Referenced mods 72
Client only 0
Server only 0
Not labelled 72

These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.

What are the server requirements for OptiCool?

OptiCool 1.0 B1. Change the pack release and its contents or setup may change too.

72 mods in this pack file

The selected pack release is OptiCool 1.0 B1. That file is for Minecraft 1.21.5 with Fabric 0.16.14. It contains 72 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.

Now let's get to the most interesting part - FPS Testing!

Why this result? Most likely because OptiCool uses optimized settings options that try to give the look of Minecraft on Fancy graphics although it's Fast and fixes the big lag issues from particles.

Пришлось поставить 12 чанков, чтобы был результат точен.

FPS с OptiCool 1.0 B1 pre1

Почему такой результат? Скорее всего из-за того, что OptiCool использует оптимизированные варианты настроек, которые придают вид Minecraft на Детальном графике, хотя это Быстрая, а также исправляет большие проблемы с лагами от частиц.

Дополнительно

В новых версиях будут обновления или добавления модов для оптимизации / модов для возможностей OptiFine.
