- what ? you can't get data to a screen faster than chipmem bandwidth.
- modern c2p routines are at this limit, so AKIKO just can't get it faster.

-
- The only useful mode in gloomdeluxe is 1x1. If I halve resolution, speed
- is only a bit faster. One might think that other handling then gfx-rendering
- os the reason for this, but when I switch to 1x1 I notice slow mapping + slow
- c2p.
-
- As I guess the interface won't allow blitter assistance, and as you surely
- can't make usage of interleaved planar modus (blitterscreen planesetup),
- gloom is just suboptimal if you got no 040.
