Review on 🎮 ezcap266 4K HDMI Input and Bypass USB3.0 UVC Game Capture with Microphone Input - Record up to 1080p 60fps HDMI to USB3.0 UVC Video Capture Card for Live Streaming, Recording, and Broadcasting by Ricardo Ware

Runs on Windows. OK. The latency is low, which is a plus, but for some reason it sometimes leads to serious slowdowns. Linux support is even worse. Although you can connect a capture device, you can't change FPS or resolution without crashing in Manjaro and Solus. It seems Linux also defaults to 640x480. Also, if you connect the audio output in OBS, the video will disappear. Updating the firmware from the site does not help. I wouldn't pay $80 for it to be honest, but I can see where it can work well. Unfortunately not for me.
