Question / Help Lowest latency capture card for monitor display?

[fredrum]

Hi All,

I am writing a piece of software that is doing software encoding and some other stuff and want to be able to capture from PS4 and XBone with lowest latency possible.

I am not looking for hardware encoding at all but a card that can display the incoming video signal on my windows screen with absolute minimum latency. Ideally 0 frames lag of course.

Does anyone know of any cards that fit this description?

Cheers

Nothing will have 0 frames of capture latency. Sorry.

I'd recommend taking a look at the Micomsoft SC-512N1-L/DVI; it's what I use, and with RGB32 capture mode on the newer drivers, I see between 20-140ms capture delay at most times. It also has a passthrough daughtercard so you can plug a TV into the other side and play on that with only the latency induced by your TV. I solidly believe that it is THE best capture card on the market for livestreaming purposes.
You can also get an XCAPTURE-1 which is almost the same thing, but in a USB3.0 enclosure.

You can also go for a Datapath VisionRGB-E2 or DVI-DL, but those are a LOT pricier, and don't capture audio. Up side, they have a direct capture plugin for OBS that removes the DirectShow overhead. But you have to split out the audio and re-sync it yourself.

On the cheaper side if you have a compatible USB 3.0 chipset there's the Avermedia Extremecap U3. They have a pretty low capture latency but people have reported a lot of erratic and annoying problems that just can't be hammered out (stuttering, hitching, growing desync, image corruption, and develops-over-time problems for longer gaming sessions).

Thanks a lot for the advice!
I recognize the name, SC-512N1-L/DVI, i think iv'e heard elsewhere too that it is meant to be good.
Bummer that there aren't any better pptions out there. 20ms is already a bit too much for me and 140 is more than 8 frames (over 60).
Might have to go with that for testing though.
Maybe it would be possible to write ones own drivers, for kicks, but that is probably past my skill level.
