When capturing 3840x2160 video using jit.grab or jit.dx.grab the maximum framerate I am able to achieve is around 35-40fps. @output_texture is 1. @unique is 1. 

I have tried with Blackmagic, Magewell, Elgato UHD/60fps PCIe capture cards.

Is this a known limitation or am I missing something?

Is anybody able to capture UHD at 60 fps?

I just had similar issues, I stopped using my BMD shuttle since, as I just learned, capped to 30 fps. I am now using Spout and capturing at 60 fps not at UHD though. I output my texture directly from jit.gl.slab into a jit.gl.spoutsender

The only way to get 60fps for me is using the Blackmagic [Native] driver, but that comes with another drawback, see my post here:
