Exordium vs Krypton

Exordium is a free, client-side Minecraft mod that renders selected vanilla interface elements at a configurable fixed frame rate. Lowering the interface rendering rate is intended to free CPU and GPU time for world rendering. Affected elements include overlays, the hotbar, crosshair, bossbars, the debug screen, titles, scoreboard, and chat. It is listed for Minecraft 1.19.4 and later on Linux, macOS, and Windows, with Fabric, NeoForge, Forge, and Quilt support. The project links to CurseForge and Modrinth for downloads, and does not require Sodium or support dedicated servers. The repository lists compatibility with several mods, including Sodium, Iris, Optifine, AppleSkin, JourneyMap, and BetterF3; VulkanMod is listed as incompatible. Only the vanilla GUI is supported, so mod-rendered interface elements may not work. Screen-setting support remains unfinished, is disabled by default, and can have transparency issues. The project is in maintenance mode, with no new features or fixes planned for bugs involving other mods.

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.
