| | I dumped my ATI card (9600) for a NVidia after fighting for a month. The
| | recompiling the NVidea drivers with each kernel upgrade is minor
| | compared to the missing 3D graphics and associated problems. (lack of
| | game support :) )
| |
| | ATI's own software does NOT support 3d and I didn't find this out until
| | after I purchased the card. :(
| |
| Robin Laing,
|
| You have to check out ATI's site.  They say their drivers do support
| 3D...  Just not opensource due to proprietary disclosure agreements
| limit them from releasing the information as opensource.
|
| Thanks,

Ok, correcting myself some more.....
XFree86 4.4.0 will contain support for 3D using ATI chipsets below
Radeon 8500...  ATI's site has 3D support for Radeon 8500 and above on
their web-site...  Binaries only!
Hmm... amazing how things change so quickly.

Just my added comments.
