I am having some issues with fog on Performer 3.1 on an ATI FireGL X1-128
video card.
Basically, there is none. We are running windows XP with the latest ATI
drivers.
This is a 9700 video card which is mentioned as being supported (I beleive
it is also the card used for the Onyx4 series).

Is there any reason why fog on Performer 3.1 wouldnt work?
Also I have had similar problems using Performer 3.02, but it appears that I
can only get vertex style fogging. Pixel based fogging doesnt appear to work
at all.

I have tested using town.perfly, so it is nothing to do with our
application, it is purely a performer/video card problem.
I should note that our NVidia Quadros have no such problem.
Any help would be greatly appreciated,

David Lannan
