Streaming Capture Card Question

[toastfacegrillah]

Hi Guys,

 

Quick question,

 

I'm looking at capture cards at the moment and I'm using a 144hz 1080p Monitor, do 1080p 60fps capture cards bottleneck the signal passing through? Or does it simply only CAPTURE at 60FPS while leaving the passthrough signal untouched and at the full 144fps? Do they increase any input lag to the monitor also?

 

Cheers, TFG

I'd like to know this too tbh

i've heard some word that if you want a display refresh rate above your capture card refresh rate that you need to have a multiple, like 120Hz. EDIT: to avoid tearing in the capture, should mention that.

 

that said, i'd be amazed if there's any card that can pass trough 120Hz.

Imagine the filesize..

I'm using a 120hz monitor anyway so thats ok (Just wrote 144hz for conformative purposes) I'm just not sure whether these capture cards repeat the signal, totally pass-through the signal and "observe" it, or splits it.

 

If this is the case then I would choose Software capture @ 60fps and deal with the added resource strain (Which would bring my frame rate down from around the 100fps mark) Or to just adopt the hardware restriction of 60fps.

 

Just to make it really clear, I do not want to CAPTURE at 120hz, I just don't want my 120hz signal that passes through the capture device to limit the monitor to 60fps.

But I mean.. With the CPU horsepower you have you should be able to crush any recording software?

OBS is great y'know. I use it all the time!

 

Play at 144, but record 60.

Looks like i'll be doing it that way, I just have a bit of a weird setup (6 monitors on 2 PC's using Synergy so it all controls as one, using network drives), and was hoping to use the 2nd PC as the Stream work horse, which made me look at the Hardware capture option.

 

The only other way I thought of doing it is using Steam Stream over network to the 2nd PC but I've never played with it so i'm not sure exactly how it works, i'll have to tinker today.

You can use 2 pc's for software recording also, how I'm not quite sure of however.

OH ok, must be some kind of server, client system, i'll look into it, cheers

of passing trough 120Hz? not a bit more than only passing trough what you're recording
