Description

What's the problem? Describe what went wrong.

All Android 10 devices affected by poor performance of Vulkan backend regardless the driver revision.
Theory was that GeometryShader extension (which was implemented) in Android 10 Adreno drivers had impact on perf, it appears it isn't.

Tab S6 Android 9 with never driver revision (and GeometryShader) has no issues with Vulkan backend

Pixel 4,3,3a XL Android 10 with older revision (and GeometryShader) are affected by poor perf.

This seems like OS issue, not driver related
