Hi Alexander,
The suggestion to move to Vulkan was in the context of devices that reported supporting GLES 3.2 but were actually running GLES 3.1 under the hood.
For PowerVR devices in general, we do not enable Vulkan on any devices prior to the new Series GPUs.
For Mali GPUs, Vulkan isn’t targeted below the G72. As for the issues you’ve identified on G76/G77 devices, these are likely use cases against older driver versions that do not affect our internal products. MSAA sppears to be behind most of these driver issues but we do not have any special device exceptions on this as it isn’t employed. It may be worth isolating Mali driver version that resolves this issue and use that rather than Android version to disable it as different device manufacturers may not necessarily be in sync step between Android and MALI driver versions.
Lastly for Adreno 6xx devices, Vulkan is limited to driver version 525 and above.
Best regards.
