I've just started the process of making sure my app works on BB 7. A few minor issues, but nothing major.
However, I am running into what seem to be frame rate/performance issues on the BlackBerry 7 simulators (the beta 9900 simulator with 126.96.36.199 and the beta 9810 simulator with 188.8.131.52).
On the home screen, swiping from "All" to "Favourites" has a terrible frame rate (I'd say 6fps). When expanding the all category, you see a similar frame rate when scrolling through the apps.
Within my app, I am seeing similar performance degredation. Within my app, I have several custom controls that support animation. On the v5 and v6 simulators, I would get approx 45 - 60 frames per second within my app (using the regular Java APIs....I'm not using OpenGL). While I haven't quantified it yet, I'd say the simulators are giving me around the same 6 frames per second that just moving around the home screen was giving me.
I'm using Win 7 64bit. My machine is about a year old. 8GB of RAM. I have been developing successfully on it for that time, so I don't think there is anything with my machien config.
Is anyone else seeing this? Is it a known issue to be addressed by the time 7 is released?
