In their own words
Krypton
Krypton is a free Fabric mod that optimizes Minecraft networking and entity tracking, with its performance work directed mainly at servers. It works on both clients and servers, including dedicated servers. Its network handlers are based on optimized Netty handlers from the Velocity proxy, using native code where appropriate. Flush consolidation is intended to reduce server CPU use and tick times and lessen the impact of speculative-execution hardware vulnerabilities. Other small optimizations target memory use and packet serialization speed. Krypton is tuned for Linux, though it should work wherever Minecraft can run. CurseForge lists Fabric and Quilt as supported loaders. The project aims to work with Fabric API, Lithium, and Sodium; compatibility with other mods is best effort. It is licensed under LGPL-3.0-only, and the maker does not guarantee stability, compatibility, or support for every setup. The project is described as feature-stable, while updates for newer Minecraft versions depend on the maker's availability and need. Listed compatibility includes Minecraft Java Edition versions 1.16.2 through 1.16.5, 1.17.x, 1.18.1 through 1.18.2, 1.19.x, 1.20.x, 1.21.x, and 26.1 through 26.3.
Nvidium
Nvidium is a free client-side rendering backend for Sodium in Minecraft: Java Edition. It uses NVIDIA mesh shaders for a largely GPU-driven rendering pipeline that culls terrain geometry. The project requires Sodium and an NVIDIA GTX 1600 series or newer GPU with Turing architecture or later. It is listed for Fabric and Quilt, and the supported platform is Linux. Listed Minecraft Java Edition versions include 26.3, 26.2, 26.1.x, 1.21.6–1.21.11, 1.21–1.21.1, 1.20.6, 1.20–1.20.4, and 1.19.4. Nvidium does not function on non-NVIDIA systems and disables itself there without affecting gameplay. It also switches itself off when Iris is actively using shaders. The project warns that mesh shader use may cause Minecraft to terminate unexpectedly. Nvidium is licensed under LGPL-3.0-only; GitHub is linked for issue reports and Discord for community discussion.
