I recently got an A3000D with a nice 4MB Cybervision 64.
It runs fine with Picasso69 on OS3.9. Only 32bit screen modes are a bit tricky, some artefacts in the right side of the screen when dragging windows etc. And these windows won't all drag immediately. No problems in 16 bit screens at all.
I bought Cybergraphx 4 and thought. let's also try that. But I got overwhelmed by the installer and all the options. After installing it and straight after updating it to the latest update, on a new clean OS3.9 & BB1+2 partition I get this:

Is it a matter of configuration? Should I check the chips being properly in their sockets or is something really wrong with the C64?
Some clear "dummy" guide on all the Cybergraphx install options would also come in handy. And I really don't fully grasp all the screen mode parameters (frequenties, sizes, etc.)
Thanks in advance!
