ATI announces that it will be releasing 3D programming
information for its video adapters - the good news here is that it's
finally getting around to doing that.
Well, ATI actually have released 3D programming information long ago
for their R100 and R200 based chips (i.e., everything up to the Radeon
9250), and we have had free 3D-accelerated drivers for these chips for
a long time. As a result, I am happily using a Radeon 9250 right now,
and a mobile 9250 is powering my laptop.
Unfortunately, ATI later fell back into the old secretive ways and
did not release programming information for any more recent chips.
Still, the R300 and R400 chips (everything up to the Radeon X850XT and
the X1250) were similar enough to the earlier ones that we got a free
3D-accelerated driver for them by reverse engineering. I have used
Radeon 9600, X550, X800GTO, and X850XT cards with these drivers. My
thanks go to the developers.
Their recent release of programming information for newer chips is
another (this time welcome) reversal in their course and was announced
some time after they were acquired by AMD (a year or so ago).
