The game seems mostly like a DX9 title with DX11 added for the hype wagon. Since DX10 introduced the fallback mechanism and DX11 has it too, we get some sort of DX10 support automatically it seems. But they ignored the fact that DX10.x can do some of those "DX11 effects". Like MSAA, for ex.
The newer STALKER games had devs that cared more it seems. Call of Pripyat can run almost everything on a DX10.1 card. You just lose some shadows and tessellation, but you still get a lot of extras over DX9 including MSAA and alpha test AA.
