Alternate Current vs Dynamic FPS

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.

Dynamic FPS is a free Minecraft client mod focused on frame-rate performance. It supports multiple mod loaders and is listed for Minecraft versions from 1.14.3–1.14.4 through 26.3.0, including 1.15.x, 1.16.2–1.16.5, 1.17.x, 1.18.x, 1.19.x, 1.20.x, 1.21.x, 26.1.x, and 26.2.0. Sodium is not required. The project is available through its Modrinth page, and its pricing model is free with a free plan. The available description identifies its frame-rate focus but does not specify particular controls or a stated performance result. Version matching is therefore the main setup detail to check before installation. Users should select a listed game version and compatible mod loader for their client.
