well i just installed and i can say its quite speedy...
and working 100% in mac os 9..
the extensions for ati are all installed + enabled.. so it must be working with the ati extensions
i can count 6 ati extensions installed + switched on
ati 3d accellerator
ati driver update
ati graphics accelerator
ati mpp manager
ati rage 128 3d accelerator
ati resource manager
i can also notice that there is not one nvidia extension present at all..
because this model never shipped with one?? and its the exact disk for the machine that it shipped with (ssw version 9.0.2 691-2500-a)
airport card is installed + workng aswell;)
so this leads me to ask.. Mactron?? why did u think the radeon 9800 pro would not work with mac os 9?
it works!!!!!!!! and its fast as hell
im also able to change resolutions to all supported resolutions!!!!!!!
up to 1600x1024 60hz (im using a 3:4 aspect ratio 1280 x 1024 monitor atm..)
i think there is a chance its not using 2d acclleration specifically but the performance of this card is so much greater that it really doesnt make a difference.. im scrolling pages in ie5 and its very fast
ok when dragging hte ie5 window to a new location i do see the "roll up" non accelleration type refresh so yes it is defintaely not using accelleration
