Light Converse - Slow fps from HogPC to LC

I'm running HogPC and LC on separate machines, connected directly via ethernet cable, no switch.
I connect no problem, but LC is seeing a very slow frame rate from Hog, anywhere between 9 and 18fps.
LC itself is running at 60fps.
I've tried running HogPC on the same machine and get the same result.
Any ideas?
