The initial drawing requests are long-forgotten, and we'd need some pretty extensive modification to all the internals to mark a particular region as being doubled. > >Specifying that pixels must be exactly _doubled_ is a > >hack around both the performance issues and a lack of resolution > >independence.

We can do more or less arbitrary scaling, yes, but unfortunately with a few limitations (either we do it on the display controller and suffer the bandwidth hit, or do it on Hailstorm and suffer its horribly complicated semantics for dealing with overlays). > This all leads to request to have some more advanced gaming API.

I don't know which division N-Gage is in. I can't speak for the product managers as to targeting market segments and all the other things they like to say. Cheers, Daniel
