Your second PC can't help your aim if it can't see the game. A
capture card is the bridge - it copies your console's video to the
PC while still showing the game on your own screen with no added lag. Good news:
this part is mostly plug-and-play.
Draft The dashed bits need your call (which cards you recommend, the exact specs). Everything else is ready to go.
How it works
The capture card splits your console's picture two ways - straight through to your
screen so you play normally, and into the PC so Joyeuse can watch. You always look at
the pass-through, never the PC, so there's no lag where it counts.
1Console's HDMI OUT → capture card HDMI IN
2Capture card HDMI OUT → your TV or monitor - this is what you watch while playing, effectively zero lag
3Capture card → host PC (a USB cable, or the PCIe card is already seated inside) - this is the copy Joyeuse reads
What you need
•A capture card - external USB or an internal PCIe card; either works. which models you recommend + minimum spec
•One HDMI cable (console to the card).
•For a USB card, its USB cable to the PC. For PCIe, nothing extra - it lives inside the PC.
Set it up
Install the card: USB - plug it into the PC and install its driver; PCIe - seat it in a slot and install its driver. the exact driver / app you point people to
Wire the HDMI chain above - console into IN, your screen off OUT.
Confirm the PC sees the signal: Windows lists it as a camera / video device, or the card's own app shows the picture.
That's it for setup - Joyeuse picks the capture format itself, so there's nothing to configure here.
The catch
Always play off the pass-through (the HDMI OUT to your screen), never the PC's preview window - the preview is delayed, the pass-through isn't.
The card has to keep up with how you play. the resolution + frame rate you support, and the minimum card that hits it
On PlayStation, copy protection (HDCP) can make the PC capture go black. confirm: on PS5 it's Settings → System → HDMI → turn off Enable HDCP Gameplay usually isn't blocked, but it's the classic black-screen cause.
If it goes wrong
No picture on the PC
Check the HDMI direction (console into IN, your screen off OUT - easy to swap), and that the card's input is selected in its app.
Picture on your TV, but black on the PC
Almost always HDCP. Turn it off (the PlayStation setting above).
Stutter, or the wrong frame rate
The card or the HDMI cable can't handle your output rate. minimum spec
