Question / Help 4k Capture card which one?

[Beardedbob]

Hi guys,

I'm looking to upgrade my gaming pc now the 1080gtx is out to 4k. I use a two stream pc setup and want to capture the 4k output via a pci card in the second pc and use OBS to downscale it to 720p before re streaming it. I wanted to know if anyone has done this and if so what capture card they are using? or if not what capture cards are available that OBS will recognise.

Cheers

Bob.

As far as i know one of the only capture cards that support 4k it's the blackmagic intensity pro, but i don't know if it supports 4k60fps, i probably would stream from the gaming pc, 4k60 @ 80mbps over LAN to the stream PC, and in this downscale to 1080p for stream.

So use something like Ngnix rather than a capture card? The only issue is the gaming PC will then has to so the steam cpu load so depending what this is could impact fps.
