Hi,

thanks for finding this, I will give a look at natfeats (possibly 
related to some prefetching/set_pc as I mentionned in a previous message)

No, it's slow in the sense that you will really see the GEM's windows 
being drawn as if pixels were plotted one after the other. At boot with 
tos 4.04, you will see that the Atari logo will flash in yellow/orange 
during a short moment instead of being black.

When this happens, this is due to an error in cycles counting that 
affects the blitter. As a consequence, every blitter access becomes 
really slow.

But I haven't seen it for a while, maybe I fixed it with some other changes.
