The fallback in D3D10 is to use a second render target and write Z there.
So, D3D10.1 should make this much faster.

Deferred rendering algorithms would prefer to be able to read the depth of each sample, as far as I can tell. D3D10 doesn't give the developer access to depth, just colour.What does DX10.1 add vs. DX10 that makes such a big difference? I was under the impression DX10 had everything necessary for MSAA with deferred shading. Sure, DX10.1 makes it slightly more convenient, but I hadn't noticed anything that makes a possible/impossible kind of difference, or even a significant performance difference.
