Not sure.

Yeah, if you have agpgart loaded and use NVAGP=1, then you're basically 
disabling AGP
functionality, so you'll lose bandwidth. NVAGP=1 is only good for 6200 
series cards with
the pre 8756 driver, AFAIK.

I have problems with stutter and jitter when I use bob. Maybe you have a 
higher refresh rate
than 60 hz? I'm locked in at 60hz because that's all my LCD TV supports.

Me too. It worked for me before, but I haven't tried it lately as I'm 
running a 6200 on my
primary machine now. I've still got my 5200 on another machine though. 
I'll give it a try
tonight and see if it still works. What revision of fixes are you running?
