In their own words
Lithium
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.
VulkanMod
VulkanMod is a free Minecraft client mod that replaces the default OpenGL renderer with a Vulkan-based engine intended to improve performance. Its listed optimizations cover terrain rendering, chunk building and entities, alongside reduced CPU and GPU overhead. It also supports native Wayland on Linux and windowed fullscreen mode. Installation requires Fabric, followed by placing VulkanMod.jar in the .minecraft/mods folder, and a GPU with at least Vulkan 1.2 support. The project lists Minecraft versions 1.21.3, 1.21.4, 1.21.5, 1.21.10 and 1.21.11. Shader support is not available, and there is no estimated release date; the README points users to Beryl for shaders. Mods that use OpenGL calls are unsupported, including Sodium, Iris Shaders, Create and Distant Horizons. Release 0.6.0 notes a terrain-rendering improvement when backface culling is enabled, an update checker, and fixes for alpha cutout sampling and a memory leak.
