Over Vulkan

Over Vulkan uses a rendering mod called VulkanMod giving it better performance than Sodium. Normal Minecraft uses OpenGL for rendering. Vulkan is a different way of rendering a game, with way higher performance. Expect an improvement of 4-5x the fps compared to vanilla.

Compatibility

Because this pack uses a different way of rendering, Vulkan, some mods wont be compatible. Mainly mods that adjust major visuals like Distant Horizons. Here is a list (note: this list is a bit outdated).

Gameplay

No significant changes are made to the gameplay, because this pack is designed to be a foundation for your own pack. You can add your own gameplay.

Requirements

To speed up chunk generation and general performance, a minimum of 2500-3500 Mb allocated memory is recommended. This is dependend on your render distance so playing with lower render distance allows a lower amount of allocated memory.
