Low-FPS on Retina-display

Hi

I have swf-app with sizes 960x480. And test it on Iphone 3gs and Iphone 4. If i build app with requestedDisplayResolution=high, i have low fps on Iphone 4, but the 3gs shows good results. I have bitmaps about 300x300 sizes (and less) on stage.

Also I use stageQuality=BEST, because I need a smooth movement of fractional coordinates

how you use requestedDisplayResolution and what fps you see?

Thx

P.S.

Tested on air 3.1, 3.0 and 2.7
