Alternate Current vs More Culling

Alternate Current is a free, MIT-licensed mod for Minecraft: Java Edition that changes how redstone dust calculates power and updates blocks. It builds networks from connected wires and spreads power from wires receiving power outside a network. The project says this makes updates deterministic and less dependent on location, while retaining high Vanilla parity.

The mod focuses on reducing server work. Its README says redstone dust contributes up to 20 times less MSPT with Alternate Current, and that network-level optimizations can reduce updates by up to 20%. Listed Minecraft versions include 1.14 through 1.21.11, with some specific releases also listed; supported versions and loaders vary by release. Modrinth lists Fabric, Forge, NeoForge, Ornithe and Quilt, and server-side and singleplayer environments. The project links to its source repository, issue reporting and a Discord server. Its GitHub repository has no detected security policy and no published security advisories.

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.
