This is a mod that introduces a brand new Vulkan based rendering engine to Minecraft in order to bring performance and graphical improvements, but even new features that are only possible thanks to the new graphics APIs.
Developing this mod requires huge amounts of time and effort. If you want to help me continue developing this project, consider buying me a coffee.

Issues
Before asking for help, if your instance is crashing check if your system supports Vulkan and if any of the mods listed in the link below is present in your instance.
Please before reporting any new issue check if it already exists.
Compatibility
Mod compatibility is not guaranteed. When VulkanMod is loaded, mods that make direct calls to OpenGL might crash the game. Check Incompatible mods list to make sure you are not using one of them.
