3DMark - Port Royal

Port Royal will test Ray Tracing in real-time which is based on Microsoft’s DirectX. Like other benchmarking tools it will present a scene and go through a series of test. Since there is exactly one test it only gives you one FPS and the Graphics Score result.

The API Overhead Feature Test will test multiple APIs that are used in most games today. Those are DirectX 11 single & multi-thread, DirectX 12 and Vulkan. Looking at the Vulkan draw calls most can easily see why I’m a huge fan of the Vulkan API. The more draw calls that the CPU can gather is better for the GPU pipepline and less chances of a bottleneck
