3.0 out of 5 starsWorks on Linux at 4K/30fps; audio mixer button doesn't work outside of proprietary software
Reviewed in the United States 🇺🇸 on July 2, 2022
This capture card, like most nowadays, claims to be UVC-compatible so I decided to test it out to see. (I'm running Ubuntu 22 with the 5.15 kernel). It worked fine (with some minor driver issues, see outputs below), although 4K capture was limited to 30 fps.
Additionally, I removed a star because the audio mixer button (the dial in the center of the capture card) does NOT work with any UVC software like OBS, for example.
Also, the software for controlling the RGB lights on the device (EVGA XR1 - XR1 RGB v1.0.0) doesn't work on Windows 10.
All-in-all, I would say that this is a fairly overpriced capture card and I wouldn't recommend purchasing it; there's other 4K/30fps capture cards for about half the price. If the audio mixer and RGB lighting were supported cross-platform then perhaps I would reconsider my opinion.
