@ 2008/12/01FarCry 2 is the first game we have evaluated that shows DX10 in Windows Vista to provide greater performance than DX9. Finally, DX10 makes a performance difference, and finally it is for the positive. We examine that A2A along with AA performance and multi-core CPU testing.

as you can see, DX10 mode is faster with midrange cards also!
