Can anyone confirm if the Rage128Pro (*) supports hardware-accelerated BltBitMapAlpha() on MorphOS 3.2 ?
(* = that's what the Power Mac G4 reports it as)

I'm trying to work-out why it is using the CPU to perform this on the above Power Mac G4, but is nicely hardware accelerated with a Radeon9200PRO on an Efika running MorphOS 2.7...


ALTERNATIVELY, can anyone suggest a program which would allow me to test whether it is h/w accelerated?

The MorphOS Rage128Pro driver neither supports 3D nor h/w accelerated alpha ops (which would use the 3d engine).

An easy test is to enable enhanced display - if you get window shadows, it means the calls are accelerated. We generally support advanced hw acceleration on R200 and R300 based cards. The Rage was added only because some PMacs were indeed sold with that card and we wanted people to be able to try MorphOS on the machines they already had. For any serious use though one should really get a Radeon 8500 to 9800.

Thanks. I was going to ask which ones do support it, but I found answer to that:

I bet 3D-supporting cards that'll plug into a Power Mac G4 are extremely hard to find (and/or expensive) these days

Dunno, the 2 Radeon9000Pro/64MB I bought last year from ebay were about 10-15Euro each.

128MB cards a much rarer and will cost about 50Euro.

Aaargh, worse than I thought: AGP card from Efika doesn't work in Power Mac G4... I guess it needs to be some super special card with Mac-supporting firmware?

Or was it just the fact that the Mac didn't like it only had a DVI output?

Suspecting a Radeon9200/9250:

a) needs to be flashed with OF-BIOS

b) depending on the revision of your PMac you might need to desolder disconnect 2 resistors


Or you go to ebäh

Hah, buying a whole PPC Mac just for the graphics card... I'll end-up calling it FrankenMac
