3DMark API Overhead Feature Test

Compare the latest graphics APIs on your iPhone and iPad with this free app.

The 3DMark API Overhead feature test is a specialized test for comparing the performance of new graphics APIs such as OpenGL ES 3.0 and Metal.

- Measure the draw call performance of the latest graphics APIs.
- Compare OpenGL ES 3.0 and Metal.
- Developed by Futuremark, the benchmark experts.
- 100% free. No ads. No in-app purchases. No restrictions.

Games make thousands of draw calls per frame, but each one creates performance-limiting overhead for the CPU. New APIs like Metal reduce that overhead, allowing games to look better and run smoother. See how many draw calls your iPhone and iPad can handle with each API before the frame rate drops below 30 fps.

This app compares the relative performance of APIs on a single device. To compare the performance of the latest smartphones and tablets we recommend the 3DMark Sling Shot app, which is free to download from the App Store.

3DMark is used by millions of people, hundreds of hardware review sites and many of the worlds leading technology companies. Its the industry standard benchmark for graphics performance measurement.
