Anisotropy support on all machines? (mipmap, filtering, image size)

hiya all,

I'm new to the QC world, and have a handful of questions :-)

I'm working with someone building an app which incorporates some QCs and I'm wanting to use anisotropy (via affine transform etc). But I have heard something about there being problems with ibooks and this (black dot?). I can use OpenGL info, but will that give me relevant info?

Also can anybody share some rules of thumbs with mipmap levels and Filtering mode. I'm finding mipmap of 4 seems to be sufficient - will this incur a lot of GPU RAM usage?

Finally, what are some good rules-of-thumb for image sizes? I'm using a few images around the screen, and i need to keep GPU+CPU usage to a minimum (As the app is doing audio work as well). My images are currently around 640x480 as jpgs.. will using multiples of these fill up GPU RAM as they are uncompressed into memory?

many thanks,

Keith
