Flash Player 'Molehill' on mobile devices

i think it's taking advantage of opengl. so all devices that support opengl get accelerated graphics. no need for per-device optimisations.

Do mobile game developers optimize their products for every GPU out there?

If it's necessary, which is more likely to have the resources to do such optimizations, Adobe or an individual developer? (Well, at least in theory... Adobe's track record with Flash Player is of course lightyears short of stellar.)
