My previous entry (p.s. you're all losers for not taking up on my question) missed out the pow2 partitioning mode that should be useful for texture based displacement mapping (2n subdivision conveniently matches mip-map levels). I chased this up with Michael Oneppo, PM for the Direct3D team and it turns out you need to use the Process**() HLSL intrinsics to enable this functionality.
At this stage I'm not sure if thats a by-product of D3D11 still being in CTP or a 'by-design' choice, but without the Process**() intrinsics it appears that pow2 results in the same output as integer partitioning.
More on this later I hope.
As an aside, I just watch Waltz With Bashir having bought it on DVD last week. Didn't realise it was in Hebrew with English subtitles! Regardless, it's definitely a film worth watching and one that I'm truly glad I now own and have watched. But I don't think I'll sleep properly tonight - it's got that sort of gravity to it [oh]. For me, I'd give it a silver medal between Oliver Stone's Platoon's gold and Stanley Kubrick's Full Metal Jacket's bronze.
