I guess Futuremark and Nvidia called a truce. Though Nvidia has been trying to bury 3Dmark (something I would agree with) so why this change of heart. (I dont agree with it's optimizations however)
Maybe Futuremark has decided to let Nvidia input on how the future of it develops like the other members of it's "club". From at least what was made public when NV was a member it and Futuremark were at odds over the direction of 3Dmark03.
I think NV intentionally put in those optimizations in the drivers (and make them detectable) to ignite the debate over cheating/optimizing and eventually discredit 3Dmark03 and stop people using it.
They already tried once with the PDF they released at the launch of 3Dmark. Seeing as Nvidia make up the majority of the video card market that's something Futuremark cannot afford to let happen as it's financial existence would be at stake.
These one click solutions are always going to be under suspicion especially if a company is behind them that can come under influence. We know SiS and Trident optimized/cheated in 3Dmark2001 and you can bet ATI/Nvidia were just better at it and didn't get caught.
A good wide range of apps(real 3D engines) are the only way to go as the companies involved can't optimize for everything that's out their or perhaps the open source community could cook up something for 3D benchmarking. Their is Rightmark 3D but its still in beta.
Also have a read of [H]ardOCP's take on it.
The sooner Futuremark and it's products go away the better is my view.
