School me on the Differences between RTG graphics card and IndivisionECS/AGA

[NovaCoder]

I could be wrong but isn't Jens working on a  driver that will allow the Indivision ECS to be used in a similar way to an RTG card? From what I've read on the forums it suggests that it will be 12-bit reduced from 16-bit at 1024x768(i.e. more colours and higher resolution)and the software will be Shapeshifter based.

new version of ADoom, which supports the Indivision GFX 256 colour direct chunky display of Indivision ECS
