Who is this for?

This modpack is for you if:

• You have a low-end PC (integrated GPU, limited RAM, low-core CPU)
• You want Minecraft to run smoothly without researching mods one by one
• You play on servers (ViaFabric lets you join servers on other MC versions)
• You are not looking for shaders or HD textures - you want real FPS

Iris (shaders) ships optional and disabled in _opcional-iris/ - enable it only if your PC can handle it.

90 / 10 Philosophy

90% Optimization	More FPS, fewer stutters, less RAM: Sodium, Lithium, FerriteCore, C2ME, EntityCulling, ImmediatelyFast, Ksyxis, BadOptimizations, ScalableLux, Alternate Current, Krypton, MoreCulling, Cull Leaves
10% Lightweight improvements	Useful or visual mods that do not hurt FPS: BetterF3, Mod Menu, Ok Zoomer, Simple Voice Chat, Litematica, MiniHUD, Tweakeroo, BetterGrassify, Continuity, Shoulder Surfing, Debugify

Everything ships pre-configured for performance: 8-chunk render distance, Fast graphics, clouds off, minimal particles (options.txt included).

Real results

Users with low-end hardware report big FPS gains. Example from our gallery:

• AMD Athlon Silver 3050U + 8 GB RAM DDR4 - 200 FPS (Fast graphics, 4 chunks)

Got results? Reply in the comments with your CPU, GPU, RAM, MC version, and average FPS - it helps others with similar hardware pick the right settings.

Supported versions

Minecraft	Status
1.20 - 1.20.6	Stable
1.21 - 1.21.11	Stable
26.1 - 26.3	Stable

All versions use Fabric. On older versions (1.20.x) some mods are missing because authors do not publish builds for those MC versions - the pack only includes what is compatible.

Server files

Optimized server-side packs (Lithium, C2ME, Krypton, Spark, FerriteCore, Alternate Current, Voice Chat) are available in the Versions tab - pick the server version you need. Drop the mods into your server mods/ folder with Fabric Loader installed.

Installation

Option A - Modrinth App (recommended)

1. Open Modrinth App
2. Search Hydra Studio Opti-Modpack
3. Pick your Minecraft version (1.20 - 26.3)
4. Install - Play

Option B - Manual

1. Install Fabric Loader for your MC version (fabricmc.net)
2. Download the .mrpack from the Versions tab (or GitHub)
3. Import the .mrpack in Modrinth App / Prism / MultiMC, or extract the mods into .minecraft/mods/
4. Copy the included options.txt (already optimized)
5. Play with the Fabric profile

Troubleshooting

• Crash on world join: check crash-reports/ - Crash Assistant usually explains the cause in plain language
• "Incompatible mods" on 26.x: always use version 1.1.1 (the 1.1.0 builds for 26.3 and 1.21.11 were removed due to bugs)
• Missing mods: some mods do not publish builds for every MC version; the pack only ships what is compatible
