I have meant displaying with scaling. Filling 1200x900 in 30fps is 
impossible I think.
IMHO there is no feature in the Geode DC which could be used by the 
rasterizer so I think it is not a problem to concentrate on this one 
feature (scaling) it can do quite well.
As I see in the DCON documentation, it simply scraps 2/3 of the frame 
buffer data when deswizzling so it seems that not generating that data 
would be a win either way.
