Support for the 3DMark API Overhead feature test ended on January 14, 2021. The 3DMark API Overhead app is no longer available in the Apple App Store.

The 3DMark API Overhead iOS app compared the draw call performance of graphics APIs. At its launch in 2015, this was the most significant difference between older APIs, like OpenGL ES 3.0, and new, low-level APIs, like Metal. 

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.
