Why do you need to download a separate 3DBench App?
-- The separate 3DBench app is to avoid re-downloading 3D part when version updated. Save your mobile data!
-- To test the 64 bit CPU and UX performance we need a separate 3DBench app
Antutu 3DBench v7 includes three test scenes, the OpenGL3.0-based Marooned, the OpenGL3.1-based Coastline and the OpenGL3.1+AEP-based Refinery which measures the performance limits of mobile devices. The benchmark automatically detects the API level supported by your device and runs the relevant 3D tests.
The benchmark results of the 3D tests in Antutu 3DBench v7 are based on Offscreen performance, which can more fairly reflect real-world gaming performance of mobile devices.
