DX9.0L

Ok so I've read all over the place that DX9.0L, the API for Windows Vista running video cards that do not support DX10, that it would be optimised over DX9.0c and as such the performance of DX9.0L would be faster.

Obviously Vista comes with its own additional overheads and drivers are in beta which means real life performance will likely be slower in Vista.

How well has this been documented on the net? I'm preferably looking for a good source from Microsoft claiming it will run faster, but so far can only really find forum posts, although the comments from the Crysis dev team are a fairly reputable source I'd prefer something more concrete.

I dunno much, but best I can tell DX9L+Vista will be much faster than DX9C+XP due to the highly streamlined way in which Vista handles DirectX stuff.

Right?

Thanks for that, I will read it through.
