Krypton Mod FAQ

Krypton is primarily a server-side optimization mod, but it can also be installed on the client. On a client it improves your own networking performance, though the biggest gains come from running it on the server.

Yes, Krypton is designed to complement other optimization mods. Lithium handles game logic, Sodium handles rendering, and Krypton handles networking, so they target different areas and generally work fine together.

No. Krypton only changes how packets are handled and flushed, not how the world is saved. It doesn't touch world data, so your existing worlds are safe.

Krypton replaces parts of the vanilla Netty pipeline, so mods that also modify networking handlers can clash. If you get a startup crash, remove other networking-focused mods and test one at a time.

Yes, Krypton works fine behind a proxy. Since Krypton's handlers are derived from Velocity's own networking code, they're designed to behave well in proxied setups.

Krypton mainly reduces CPU load from packet flushing and serialization, which lowers overall tick times. It won't fix lag caused by entity AI, chunk generation, or redstone, so pair it with other optimizations for those.

Krypton uses less memory than vanilla networking because of its micro-optimizations, so it won't increase your resource usage. It's a net reduction, not an addition.

No configuration is required. Krypton works out of the box with sensible defaults, and there are no player-facing settings to tune.
