Seems that automatic image scaling does not to work with texture packs atm.
http://www.giderosmobile.com/documentation/automatic_image_resolution.htmlThe sample project with single images works, but the project "Automatic Texture Pack Resolution" shows always the lowres image. Tested on the windows simulator!
EDIT: I fooled myself by thinking, when I change the resolution in the simulator with a running app, it would reload the images.
