RE: GL_LINE_SMOOTH broken on ATI Radeon 9600 Pro

Hi ,

The Radeon 9600 and later cards from ATI have no hardware support for AA
polygons, so unfortunately there is nothing that can be done to address this
missing driver feature.

As far as AA points and lines go, those features are present in the
hardware, but not yet exposed by our GL drivers. We do have plans to
implement them, but I can't comment on when drivers will be released with
those features supported.

Again, for your particular case, I recommend looking into using the
GL_ARB_multisample extension. For Radeon 9600 and later, the hardware is
extremely efficient at handling full scene AA. Adding support for that
extension should be trivial, and unless you are graphics bound in your paint
application, you should not see any performance drop.

I hope you can tell us that this is being fixed as fast as humanly
possible.
My 2D paint application depends heavily on antialiased polygons, and I
was
quite disappointed today to see that it looks like crap on my brand new
15" AlBook.

Actually, I am quite surprised that you even allow drivers to ship with
this functionality broken.

:(
