🗺️Origin of VulkanCore Began:
"VulkanCore wasn’t made to be public at first. It started out as my own private optimizer an all-in-one collection of tweaks that I built and used only for myself during my streams for a very long time.
VulkanCore wasn't named VulkanCore at first the first name of this was Lithium_Optimizer before changed the name as it grew into something bigger and more reliable and powerful.
I chose to publicly share it because of my loyal and supportive followers who kept asking where I got my performance settings. I polished it up for everyone, so what began as my personal setup can now help anyone run Minecraft Bedrock smoother and better."
