Frame rate performance on the beta BlackBerry 7 simulators

Hi all,

 

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 7.0.0.89 and the beta 9810 simulator with 7.0.0.103).

 

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?

 

Thanks,

Mark
