Question / Help Help setting up OBS to use a second PC to encode?

[CobR]

I have a GTX 780Ti and i7 4790K on my main computer and on my second machine I have an i7 920 @4.2GHz. I would like to play the game on my main computer and encode the stream on my second. How can I do that? I read that there is a way to duplicate the display with NVIDIA and then just use window capture but I don't know how to do that and I don't think that I am searching the correct thing in Google.

I use a 144Hz monitor on my main computer and I would like to keep the ability to play at 144Hz. I found a vid that utilizes a capture card but that means I would have to play the game at 60Hz which I do not want to do.

The best way to do this is to run each display independently, your main monitor 144hz and the cap card and 1080@60hz then use an OBS session with game capture on the gaming PC and "project" the display on the cap card's "monitor". make sure you check dont encode while preview on the game PC's OBS or else you'll use up, unneeded CPU.

Once you get it there, run OBS on the stream PC like normal with capture card as source and go from there to downscale.

Second recommendation is the 920 should be able to game about the same as the 4790K, but OBS WILL utilize the extra power with the 4790K so I would swap them. yes your i7 920 has PCIE 2.0 but that will make no difference as long as its running at PCIE 2.0 16x.

Also, USB3.0 is a must with capture cards (or a PCIE cap card) so the 4790 would handle that better as well.

USB 3.0 is only for the Elgato HD 60 and Avermedia Extreme Cap u3 ...so thats not really even close on the requirement of usb 3.0. The obvious answer here is a capture card, buy a DVI splitter rated for high refresh rates. I don't think I need to go further do I?


you'll also need a DVI to HDMI cable

Since OP did not specify which capture card, I figured I'd cover all the bases. Most splitters I see cost around $150 which dont specify high refresh rates explicitly, it would be better if you would link him one that you know that will work, especially for the $ some of those cost.
I have many blackbox DVI splitters at work and non show native support for 144Hz, even with duallink DVI ports.

for contrast, my solution is free of cost provided that OP is already getting a cap card and has the second PC. Not to say you are not correct, I'd just like to see a link to the splitters you are suggesting so, in the future, I can recommend them to those who need it.

Elgato does not have a USB 3.0 device
