MSAA and DEPTH

Please help! Without MSAA very bad (arma, dayz) how do I set the depth to work with msaa, maybe 2048x2048 x2 x4 x8????

MSAA can break (remove?) the depth buffer in some game, so I'd try disabling MSAA and using ReShade's SMAA (and / or FXAA) instead and see whether you have depth buffer access then (use DisplayDOF).

FSAA(with ATOC) in Arma3 won't break Depth Buffer of Reshade, just tweak the settings in Depth Buffer Detection Modification tab.

edit: You have to manually select the correct depth buffer layer whenever you open a new sceneriao.
