I am having difficulty with antialiasing on a Performer app on iR.

I have an Onyx/iR with (2) RM6s and Performer 2.1. When configured with (3)
1280x1024 output channels, the irconfig utility tells me the pixel depth is
"small". My understanding was that this would allow (4) subsamples, and this
seems to be verified by the pfQueryFeature(PFQFTR_MULTISAMPLE) which returns
PFQFTR_FAST.

However, running this app shows substantial aliasing, and no perceptable
difference between antialias on/off.

What am I doing wrong?

Any info would be appreciated.
Thanks,
Shawn
