It's a very pretty way to show off modern hardware, and Macci et al will love to race to 10K and beyond, but its use as a serious benchmark is let down by use of an accelerated method of PSM rendering that's yet to show its face on anything other than XBox and which isn't a standard part of DirectX, leaving its means as a rendering technique on PC games in the future in doubt, calling into question the reasons why that method of PSM rendering was ever included in the first place. Performance certainly seems to be one factor.
It remains to be seen how it'll pan out in the future, after all they're not called Futuremark for nothing, but the reasoning behind the way it was designed still needs to be investigated. Stay tuned.
