If you do get it working, don't expect too much from a Z2 card when it comes to streaming video / doom style games. The typical maximum data throughput of Z2 is less than AGA.

Of course for normal desktop use (moving windows around etc), any graphics card that has a working blitter and chunky pixels will run rings around the native chipset.

@Xeron

I was generalising, but in my own experiences anything that can take advantage of 2D acceleration on your desktop tends to enjoy a supported graphics card, even if the bus is slow. Just  look at the Siamese RTG - you sent your rendering instructions across a serial link there ;-)

Perhaps it is possible in Z2 mode that the blitter doesn't function correctly? If it had to be done in software it would die a death on a Z2 bus :-/

-edit-

Hence the "working blitter" remark in my original post ;-)

Your guess is as good as mine *shrugs*

Generally the level of acceleration offered by P96 or CGX is dissapointing. Common 2D hardware operations like stretched blits, colourspace conversion etc. tend to go unutilised. For those features that are used, it's often the case that the overhead of the whole rtg system (specifically how it interfaces to intuition/graphics) sucks a large initial proportion away too. However, it should all still be much faster than AGA ;-)
