Virtual Texturing Feedback

Just curious.
I have literally never seen any benefit from using VT on a landscape or on anything at all really.

Forget the landscape because usually the texture is tiled anyway, so there wouldn’t really be any benefit anyhow.

Is there a content example or something where enabling/disabling the features shows some clear ms cost reduction?
(Where the object isn’t just using 10% of an 8k texture, since the benefit of that would be evident?)

Is VT really only intended to lower the memory footprint or should I be getting some ms benefits in the rendering pipeline as well?
