The scene achieves 60Hz at times, but feels choppy, and I notice the middle two GPUs at times show long orange bars, which are killing the 60Hz rate.

This is probably obvious for you, but the "fancy" aero rendering is turned off, right?

I set the theme to "windows classic", which I assumed would do away with the aero stuff (with no discernible difference), but is there something else to specifically turn off?

No, with turning aero "off", I meant to switch to classic. When having aero on, i have discovered that osgviewer reports 60hz, but the real frame rate i clearly bellow 60hz.


or 2 double-wide screens (screen 0 & 2, each set to 2880x900). Note that in the Vista display settings all 4 screens are set up as 1 big "extended desktop".

How do you configure "extended desktop" in Vista? I mean, microsoft (or nvidia) has removed the horizontal/vertical span possibility. But if I understand you correctly, there is a possibility to "fool" vista, so it believes your multiple monitors is only one monitor with a very large resolution?
rt.click desktop->Personalize->Display Settings (Monitor tab) shows 4 monitors that you can select, then check the "Extend the desktop onto this monitor" box.

So if you have 4 1024x768 monitors. Can you make Vista believe that you have ONE 2048x1536 or 4096x768 monitor? (as with nvidia's vertical/horizontal span)

rotates with a discernible choppiness. Is Microsoft punishing me for disabling dwm?
