neat :) i have seen better performance on similarly (and worse) spec'd ARM devices, however, so i'm wondering what might be causing some of the issues seen in the video. one thing i did notice was when creating a new activity there were graphical glitches that look to be driver related? there are also visible artifacts on e.g. the panel shadow which is rendered as a black block or when applications are started (similar atrifact as when creating an activity). it's a very interesting start, but sorting out which problems are at the OS layer and which are due to PA itself would be very helpful to knowing where we need to focus attention (as we can improve the latter, but do less about the former) > GLES HW accel is in effect, you can see a significant improvement, but the > responsiveness is still not real time. keep in mind that the shell itself is still using QML1 which does not have the full opengl rendering system that QML2 does. i suspect (based on playing with it :) that when we switch to QML2, we'll see a much more useful and visible jump in performance with GLES accel HW. one more reason to push forward to Qt5 -- Aaron J.
