Android Vulkan driver results

• compute_nbody5% slower
• hdr_2160p4% faster
• oit_linked_lists2% faster
• pipeline_barriers9% slower
• subpasses10% slower

Custom driver against stock, per scene. Bars to the right are faster, to the left slower.

Small areas of the picture differ from the stock driver in 1 scene (pipeline_barriers: 1935 of 2304 cells). The picture matches overall, so this is a local rendering fault, not a different scene.

Not on equal terms: the GPU clock differed during 2 of these scenes (for example compute_nbody: stock at 92% of the device's maximum, custom at 100%). Part of the frame-time difference comes from the clock the device chose, not from the driver.

• compute_nbody51% faster
• hdr_2160p15% faster
• oit_linked_lists2% slower
• pipeline_barriers14% slower
• subpasses7% faster

Custom driver against stock, per scene. Bars to the right are faster, to the left slower.

Small areas of the picture differ from the stock driver in 1 scene (pipeline_barriers: 1234 of 2304 cells). The picture matches overall, so this is a local rendering fault, not a different scene.

Did not start every time: oit_linked_lists (stock 0 of 3, custom 3 of 3).

Not on equal terms: the GPU clock differed during 1 of these scenes (for example compute_nbody: stock at 620 MHz, custom at 836 MHz). Part of the frame-time difference comes from the clock the device chose, not from the driver.

Custom driver against stock, per scene. Bars to the right are faster, to the left slower.

Small areas of the picture differ from the stock driver in 1 scene (pipeline_barriers: 1288 of 2304 cells). The picture matches overall, so this is a local rendering fault, not a different scene.

Did not start every time: hdr_2160p (stock 3 of 3, custom 0 of 3), subpasses (stock 3 of 3, custom 0 of 3).
