This modpack is an unofficial Vulkan-based version of Fabulously Optimized. It focuses on reducing lag by including a variety of optimization mods. The core mod is VulkanMod, which replaces OpenGL with Vulkan to improve performance. Other included mods, such as FerriteCore, help further optimize the game, while utility mods like:
Controlify – enables controller support
Capes Mod – allows you to equip any cape you want
This modpack makes Minecraft much more enjoyable to play on low-end or modest PCs, thanks to its performance improvements.
Performance will vary depending on your system. If you have an AMD GPU, you’ll likely see the best results with this modpack. For users with an NVIDIA GPU, it's recommended to try both this modpack and the standard Fabulously Optimized (with Nvidium, if compatible with your Minecraft version) to find out which works better for your setup.
