Tethering nightmare D800 continues

Hello

As far as I understand my Nikon D800 will not tether to Lightroom or Capture 1.

It will tether to Aperture but it seems that Aperture is painfully slow.

I have upgraded from a D300, and tested this out tethered on Apeture as well, (incase it was the large file size of the new camera that was slowing things down) but it clearly runs around 5 times slower than lightroom even with the D300 files.

I am a professional beauty / fashion photographer and clients expect my camera to be tethered. So I am feeling slightly paniced! I also shoot fast - very fast so it needs to keep up with me.

Does anyone have any idea what other capture softwear would work at a faster speed?

Really hope someone can help.
