CS4 running extremely slow compared to CS3 - Adobe Photoshop

After a quick read of the conclusions there, "Vista performed as expected or slightly slower than XP."

Not hardly screamin'!

that's pre sp3...

And pre sp1

Pointless argument.

Just to get back to the topic, I notice a significant difference in 3D speed when I turn vertical sync off in the Photoshop GPU parameters. Have you guys tried that?

Anybody have any ideas? I have updated to the latest drivers for my GPU. I am considering just a reformat and install.
