This is Astonishingly Swift Vulkan. This pack focuses on delivering the best performance, while keeping OptiFine features, like zooming and dynamic lights.
This modpack builds on the Astonishingly Swift modpack, but adding VulkanMod and focusing on mod compatibility. This means that this modpack can't have Sodium for example, but it still performs better in some cases than Astonishingly Swift.
For the best performace, give the pack 4GB(4096MB) or more RAM. Don't give the pack more than half of your RAM capacity.
For the best performance, always use the latest Java available from oracle.com, and set it as the preferred Java installation.
