Futuremark just released 3DMark v2.3.3663 with support for Vulkan in their API overhead test...this means you can now compare the API performance of Vulkan, DirectX 12, and DirectX 11 with one easy-to-use test...The Vulkan test replaces the Mantle test found in previous versions...we ran some quick tests to see what is happening...
