Purpose: Alternate Current is an efficient, non-locational redstone dust implementation that reduces lag by optimizing power calculations and block and shape updates.
Performance: The README says redstone dust contributes up to 20 times less MSPT with Alternate Current while maintaining high Vanilla parity.
Predictable updates: The mod makes redstone network block updates deterministic and less dependent on location.
Network calculation: It builds networks of connected wires and spreads power from wires receiving power from outside the network.
Reduced updates: The README says each wire emits 24 block updates and 6 shape updates when its power changes, and network-level optimizations can reduce updates by up to 20%.
Supported game: The project supports Minecraft: Java Edition, with listed versions spanning 26.3 through early Minecraft releases.
