I am using AM-3517 CPU with SGX graphics coprocessor and OpenVG driver 1.1 (update release) - also tried 1.0.1 official release.
Drawing a stroked path vs. drawing just a filled path causes 4x-7x increase in time to render the path. For example in our test we do 160 frames in 65 seconds if we do just fill path, and 240 seconds if we add stroke. I tried all possible parameters for the stroke (I just need a thin gray line around the path). Using render quality 'fast' instead of 'best' improves about 15%, but it still seems very slow. We do need to use anti-aliasing.
Is there an explanation for this? is it possible that stroke generation is done by the CPU, and not SGX? Is that something that can be additionally accelerated and how?
