It might work, it can't hurt to try it. As I understood it though DX10 AA flags are rare, dunno why, most likely it's because unlike DX9, MS/CSAA can be used with deferred rendering under DX10 and DX11 so those games should support AA in-game. I'm just guessing though. Speaking of DX11 and AA support, why does Deux Ex: Human Revolution only have support for edge-based AA and FXAA under DX11 (the DX9-based Duke Nukem Forever also includes those AA options too)? Why doesn't it support full MSAA? I'm hoping it's because the game is in beta and not finished because surely DX11 should support MSAA and CSAA without forcing them through the driver?
