Support for the 3DMark API Overhead feature test ended on January 14, 2021.

The 3DMark API Overhead feature test was released in 2015 to coincide with the launch of Windows 10 and DirectX 12. The test compares the draw call performance of graphics APIs. At launch, this was the most significant difference between older APIs and new, low-level APIs like DirectX 12, Metal and Vulkan. 

Today, developers are more likely to choose a graphics API based on feature support and compatibility. Draw call performance is no longer the deciding factor. 

UL has no plans to update or replace this test.
