KillZone2 (a PS3 title) is based on a classic deferred renderer + MSAA and runs on NVIDIA hardware. This should tell us that NVDIA got at least DX10.1 features working way before AMD/ATI and way before DX10 was even finalized, it's not like they don't know how to do it.The real question is if there are any games under development with deferred shading/shadowing with a 10.1 path for MSAA.
