Dynamic FPS vs Lithium

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.

Lithium is a free Minecraft mod that optimizes game systems to improve performance. Its work covers physics, mob AI, block ticking, world generation, chunk loading, explosions and redstone wire calculations. It runs on both client and server, but does not need to be installed on both sides. The project says it does not alter game mechanics or visuals and is compatible with most other mods. Lithium supports Fabric and NeoForge. Stable optimizations are active after installation without extra configuration; players can disable individual patches to address bugs or mod compatibility issues, though changes take effect only after restarting the game. The project directs downloads through Modrinth or CurseForge. For multiplayer server administrators, it says improved tick times can let hardware support more loaded entities, chunks and players. In single-player, it optimizes Minecraft’s internal server and may free processor capacity for frame rates and responsiveness. Automated bleeding-edge builds may include unfinished code, bugs or crashes, and are intended for people comfortable debugging software.
