Important Information
This modpack includes VulkanMod to improve rendering performance on supported systems. Because VulkanMod replaces Minecraft's default rendering engine, not all mods are compatible with it. If you experience issues with a particular mod, it is likely due to VulkanMod compatibility rather than the modpack itself.
This pack is focused solely on performance optimization. It is not intended to add utility, quality-of-life features, or gameplay changes. Every included mod has been chosen to improve FPS, reduce lag, or enhance overall performance while keeping the Crusalis experience as close to vanilla as possible.
