The difference is that with any fully MorphOS-supported card installed in the X5000 you can still run OS4 in 2D, while with any fully OS4-supported card you cannot run MorphOS at all.

To be fair, this was only one single developer ;-)

Seems they didn't learn from the previous Sam460 fiasco ;-)
(In their defense it should be said that by the time MorphOS was released for the Sam460, the Sam460ex had been superseded by the inferior Sam460cr which had several MorphOS-supported components removed that never could all be replaced by supported PCIe cards due to a severe MorphOS bug even unresolved today, AFAIK.)

> The OS4 side went completely without 3D acceleration at all on [...] X5000

This is not true. The graphics cards the X5000 was delivered with were 3D-supported (Warp3D, Warp3D Nova, OpenGL ES 2) by A-Eon right from the X5000 release in 2016.

We're talking about 5 years ago for Warp3D and 4 years ago for Warp3D Nova.

The Sam460 port was released half a decade ago :-)

...and emulators on cheap x86(-64) hardware (see Z3 RAM usage enabled by Hyperion).

Yes, one really wonders how the unpaid and certainly non-trivial Sam460 and X5000 ports fit this goal.
