That's interesting.
Some d3d10 docs list this indeed as 15+1 (and that +1 is really needed
too for the immediates, as you can have indirectly addressed immediates
which are little more than ordinary uniforms for the hw).
So does d3d11:

How sure are you about this? This would make it very annoying to
implement on recent (kepler+) nvidia hardware... there are 16 constbuf
positions total, of which one has to contain texture descriptor data
(mandated by the hw), and it's common to have at least one
driver-internal one. If you're care

I believe that DirectX offers 16 UBOs, with one reserved for special
purposes. This means that the practical lower bound is 15, even if
OpenGL only mandates 12.
Without this, Shadow of Mordor shaders fail to work because of limit
checking around GL_MAX_UNIFORM_BUFFER_BINDINGS.
