What image format are you using? Mocha Pro will output 32-bit float distortion maps as long as you write to a format that supports it. I know Mocha supports tif/dpx for sure which would both work, I'd choose exr if it was available but haven't used Mocha in quite a while.
The loss of precision at 16-bit may not seem like a big deal but it nearly always causes artifacts.
