Funnily enough I get reversed results; when drawing as:
MultiSampledFBO -> NormalFBO (texture) -> Framebuffer
I get around the same FPS on an nVidia 8800 as rendering to the
framebuffer directly (without multisampling enabled).
I have never used PBuffers though, so I can't help there, just sharing
my experience.
Cheers,
Ruud
