closed[Android] Android 10 Vulkan backend perf regression
0%
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

How much of a performance difference are we talking here? 5%? 20%?

If it's such a significant regression, whatever is causing it should show up in a profile. Just needs someone to do so as I don't have a device with newer drivers.

Has this been confirmed to happen on non-Adreno devices?

I've only confirmed it on an Adreno device. Mali is unknown.
