I've seen that in DX11 it's allowed to provide "Fractional Viewports" :

"Direct3D 11 supports fractional viewports; the parameter types are floating-point numbers."
From the docs:

Does someone here know what is the meaning of it? and what potential usage it has?

It simply allows for more precision in the viewport transformation.

Hi Nik02,

Do you have an example of potential usage in it? (A specific example)
