Hi,
I don't have nor this card nor cybergraphx but i'm using picasso 96 and there are some options to emulate amiga native mode (normaly done by AGA/ECS chipset) by the RTG card, i've tested it what a difference with ECS whaouh blasting !! but compatibility is very average, so if you use your favorite wordprocessor it should run fine without interlacing artifact and so on but don't expect play games that use native modes !
