Depth buffer not working [Fallout New Vegas]

ReShade can't hook depth buffer in Fallout New Vegas, I guess.

I tried several times to get it done, but DisplayDepth just shows complete white or black screen.

The compatibility list says that FNV is fully compatible, so I just can't figure out what's the problem.

Somebody plz help

Update) I re-checked forums and boards on my own, uninstalled and re-installed ReShade and noticed these things:

1. ReShade with FNV can only detect character's hand depth buffer in first person mode, but can detect all depth buffer in third person mode.

2. Something's wrong with FNV's depth buffer; when I choose 1280x720 for screen resolution, FNV generates(or ReShade detects) 1280x1024 depth map, which makes bizarre screen ratio for AO effect. Kinda weird, because ENBseries can detect and apply AO with no problem.

Do you guys know how to fix these?
