Performance-wise this thing leaves everything in the dust right now. It even plays Mednafen PSX at non-slideshow framerates. I'll do some proper speed measurements with the various cores later on but so far this is one area where this thing delivers on the hype at least - VBA Next is fullspeed with both FF5 and FF6 so CPU-wise it's already way better than PS3. I have yet to test shaders extensively - I'm expecting sub-Intel HD4K performance but even that would be very, very good for an Android-based 'tablet'.
Bad thing about it - it's Android - audio/video latency is still not right even though audio latency has vastly been improved - despite all the improvements it's still quite bad compared to an iPad sad to say. You can avoid audio crackling by turning threaded video on but that will introduce jitter in video instead. It really depends on whether you can stomach frameskip-like tearing video - that's what it basically comes down to. It is less than ideal in any case compared to just turning vsync on and having audio/video sync be mostly stable - iPads/iPhones sure as hell deliver there thanks to CoreAudio and iOS.
Best results for now is to enable threaded video and set 'Forced refreshrate' to 59.6 and put up with the jittering for now. Maister is going to look at some kind of adaptive jittering method for threaded video using timers - so we'll see how this pans out.
Anyway - I can pretty much confirm by now that this issue is entirely related to Android and it is not hardware-related at all - this thing smokes every single ARM device under the sun right now but unfortunately the OS can't deliver on tight emulator audio/video sync usecases - which is why for practical purposes an iPad 2/Mini could still beat it on that level. So for now - either you sacrifice non-tearing, non-jitter video or you sacrifice audio quality.
Hopefully at some point we can arrive at a 'hack' that can solve this problem for us on Android for most devices - it is a platform too big to ignore but at the same time it's an OS too shit to be able to do the job properly through conventional means.
