Running the game in dx10

[Neon]

Anyone else got the game running well in Vista Ultimate 64 using dx10 and nvidia 169.25's?

Mine looks utterly superb, but with everything on runs like a dog, even with SLI turned on!

I have knocked off the Ansitropic Filter, Weather, and all the other bits, knocked a few things down and it looks decidedly dx9 then, runs great mind, but kinda defeats the object, anyone had any luck tweaking bits and bobs in Vista for this ?

If you're feeling brave enough you could try SP1 for vista, yes its a release candidate atm but it might help?
