Depth Buffer not working in Battlefield 3

Long story short, I've been trying to get the depth buffer working in battlefield 3 for quite a while now. I can't use effects like DOF or MXAO due to this. The display depth shader just shows a white screen. What am I missing here? I even saw a video where a guy used Marty's RT shader in bf3 which requires the depth buffer too.

Have you tried disabling MSAA?

Wait, are you trying to use depth buffer in multiplayer? Because it is automatically disabled for anti-cheat reasons.
