About this Mod

DeckTweaks

DeckTweaks lets you control render distance, simulation distance, and master volume on the fly, directly from your keyboard or Stream Deck, without ever opening a menu.

Every change shows as a clean, minimal toast notification in the bottom-right corner of your screen, so you always know what's happening.

Features

Render distance — increase or decrease on the fly, chunks reload instantly
Simulation distance — tweak how far the game simulates without restarting
Master volume — adjust in 5% steps while staying in-game
Toast notifications — subtle, styled HUD notification for every change, no chat spam
Stream Deck ready — all shortcuts are simple two-key combos that map perfectly to macro buttons

Keybinds

Keybind	Action
`Ctrl` + `.`	Render distance +1
`Ctrl` + `,`	Render distance -1
`Ctrl` + `]`	Simulation distance +1
`Ctrl` + `[`	Simulation distance -1
`Ctrl` + `=`	Master volume +5%

Frequently Asked Questions

DeckTweaks server crashes on startup – what to do?

Most common cause: wrong fabric 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 (1.21.11). You can switch loaders with one click in the panel.

Is DeckTweaks compatible with fabric?

DeckTweaks officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with DeckTweaks – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if DeckTweaks 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.
