Don't know if it helps but you can use the show depth from Sweetfx 2.0
Download Sweetfx 2.0 with reshade 2.0.3 from
here
and follow the tutorial from MartyMcFly
here
in the part that says
Use SweetFX 2.0 with ReShade 3.0 (temporary solution)
>from there just enable USE_DEPTH=1 (i think that's the name) from Global_settings.txt in the SweetFX folder and enable the Sweetfx.fx in-game
(also don't forget to disable any other effects enabled by default in the sweetfx config, like SMAA and stuff)
