As a follow-up: was struggling with some AA issues with my current project. While trying to trouble-shoot the cause I noticed a behavior I can't explain. The reporting now works just fine (reports my command-line settings properly), however when I try to specify Antialias_Gamma=off it doesn't parse, but WILL pass the -AG option (no nag) while STILL reporting that it's on at my specified value. Was it intended to have AG on all the time, when any AA is used (at the default or user specified value) ... shouldn't I be able to turn this option off if I wish?

"Neutral" behaviour can be achieved with Antialias_Gamma=1.0; I'm not sure why -AG doesn't give a warning. Maybe it should be changed so that Antialias_Gamma=0.0 (or =off, or -AG) is interpreted as Antialias_Gamma=1.0.

Displayed value is now 2.5 for benchmark. Looks good.
(beta 39 from sources (via perforce))

I would like to suggest to close.
