As discuss before, A17 improve performance but it add more content and complex logic than a16, so the performance improvement is used to compensate the extra content, so you will get same/similar FPS with a17.

On Serious Note, It was said that end of july we get Experiemental release, and we understand that timeline goes off due to some problem, but I think MM game play should hit by now, and if not already in next 2 days we should see MM. Because once MM game play is released I guess it still take 15 days to release to public, so how wrong your timeline can go wrong, it is 15 days already huh?
