Dave, I just read UK PC (well it was something about UK) today and it had an interview with some nVIDIA guy who I forgot his name. They were talking about how the NV30 was behind and the NV35 placed them back on track. (poor IQ with great speed )
Other than that there was mention of the Futuremark-NV joint statement and calling those "optimisations" and they don't change IQ (which Dave has disproved ages ago).
This information is very late for next months magazine.
Correction: The mag is called PC Plus and it is a UK based magazine.
