Thanks for the details. I could confirm that none of those extensions were supported
by the driver.. I hate ATI.
By the way, may i suggest you two tricks for antialiased scene rendering?
- The standard but efficient one: render to texture bigger than display, and show that 
texture with
multi level linear or filter4 minification filter. Uses more memory, but gives perfect 
results. without lots
of hassle.
- One i've tried two years ago at my company. Gave very good results, while 
transparencies may
need tweaking, but i guess that you are smarter than me and will find a way: render 
the scene, render
it a second time, but only the edges of polygons, and of course, with edges 
antialiased. You'll need to
do that for the solid pass, then again for transparency pass. It is very fast.

See you.
