Ah, its mistake, its fixed after swap X and Y channels in normal map.

Quick question before closing this officially: Did you have to manually swap that out, change the game file's normal map, or something else? I want to make sure that the mapping isn't wrong in the code even if there was a manual fix.

Yep, texture has DXGI_FORMAT_BC5_SNORM format and after save it into tga i swapped red and green channels and smoothing after apply normal map looks absolutely correct like as ingame. Normal vectors looks correct in my opinion.
