About this Mod

OfftiFine

This mod restricts OptiFine's network connections.
By default, all connections (telemetry, crash reporting, version checks, capes, etc.) are disabled. However, the capes function may be restored in the mod's options.

Additionally, this mod fixes the FPS Limit resetting on each relaunch with OptiFine + OptiFabric on Ornithe.

This mod is built against java 17.

The mod's logo depicts the OptiFine icon below a disabled wifi icon which is sourced from https://lucide.dev

Frequently Asked Questions

OfftiFine server crashes on startup – what to do?

Most common cause: wrong ornithe version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.8.9). You can switch loaders with one click in the panel.

Is OfftiFine compatible with ornithe?

OfftiFine officially supports ornithe for Minecraft 1.8.9. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with OfftiFine – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if OfftiFine consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
