Futuremark adds Vulkan to API Overhead feature test

Published: Mar 23rd 2017, 10:07 GMT   Comments

Futuremark has just released a new version of API overhead test with Vulkan support.

API Overhead feature test with Vulkan

The latest version (1.5) of API Overhead test replaces Mantle API with Vulkan. This new low-level API is slowly becoming an interesting alternative to DirectX12, which is the only API requiring Microsoft Windows 10. Doom, which is the part of the most iconic game series has proven that great graphics do not require DirectX12. Even Star Citizen developers recently decided to replace DirectX12 with Vulkan for their highly anticipated game.

The API overhead test is available in Professional and Advanced editions of 3DMark software, sadly it is not included in the Basic edition.

Press Release continues:


Vulkan is a new graphics API that provides high-efficiency, low-level access to modern GPUs in a wide variety of devices from PCs to smartphones. APIs like Vulkan and DirectX 12 make better use of multi-core CPUs to streamline code execution and eliminate software bottlenecks, particularly for draw calls.

Games typically make thousands of draw calls per frame, but each one creates performance-limiting overhead for the CPU. Vulkan and DirectX 12 reduce that overhead, which means more objects, textures and effects can be drawn to the screen.

The 3DMark API Overhead feature test measures API performance by making a steadily increasing number of draw calls. The result of the test is the number of draw calls per second achieved by each API before the frame rate drops below 30 FPS.

The purpose of the test is to compare the relative performance of different APIs on a single system. The API Overhead feature test is not a general-purpose GPU benchmark, and it should not be used to compare graphics cards from different vendors. For more details, please read the 3DMark Technical Guide.

Download 3DMark v2.3.3663

The API Overhead feature test is available now in 3DMark Advanced and Professional Editions. Standalone versions will prompt you to download and install the update. On Steam, 3DMark updates automatically. The API Overhead feature test is not available in 3DMark Basic Edition or the Steam demo. Note also that the Vulkan test replaces the Mantle test found in previous versions.
