Krypton vs More Culling

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.

More Culling is a free Minecraft: Java Edition mod that changes how the game skips rendering objects the player cannot see. Its project wiki describes techniques for block states, item frames, leaves, and paintings, along with custom culling shapes and model shapes for resource packs. API guidance covers custom block culling and troubleshooting culling issues on modded blocks. The listed Minecraft versions are 1.18.x through 1.21.x and 26.1.x through 26.3. Fabric, NeoForge, and Quilt are listed as supported loaders. The project information lists client-side and client-and-server environments, while the supplied compatibility details specify client scope and no dedicated server support. More Culling requires Cloth Config. The related MoreCullingExtra extension adds culling combinations involving glass panes, glass, and beacons. The mod is licensed GPL-3.0-only. Its maintainer permits modpack use with attribution, but asks users to obtain permission before merging it into a client or another mod. The project directs bug reports to its issue tracker and also links to a Discord server.
