AVerMedia Live Gamer Duo GC570D 4Kp60 HDR-Passthrough PCI-E Capture Card - Ultra Low Latency for Xbox, PlayStation & PC Gaming - Perfect for Live Streaming & Esports Tournaments

I can only speak for my personal use case, and for what I bought this for, it's perfect. I bought the 4K Live Gamer for capturing 4K footage of retro games for my youtube channel and it's handled everything I have thrown at it with almost zero lag.If your intention is to use this capture card in a similar way to me, then it will do everything you want. I originally used this with the OSSC, with the 4K Live Gamer accepting every signal I input. I have since bought a Retrotink 5x, and while researching before buying the Retrotink, I saw many not getting the 1440 signal detected by the 4KLG. I bought it anyway, as 1080p was acceptable, and I wanted the composite signal the Retrotink accepts. I was pleasantly surprised when the 4KLG accepted every signal the Retrotink x5 output. This is the same for the OSSC, I saw scaremongering of the same type about OSSC not accepting signals, but unless I received some magical version of the 4KLG, everything works great.Consoles I have tried are as follows; NES, N64, SNES, Megadrive, Mastersystem, PS1, PS2 and OG Xbox. Note though, consoles that require it, have been modded to output an RGB signal (which most stock retro consoles will not do), and I have spent £100s buying the best quality retro cables and modding my consoles which helps the signal quality. Regardless though, at the end of the day, all these consoles signals are being processed through the OSSC or Retrotink 5x, so if you are planning to use these upscalers, this is the ultimate capture card. I cannot speak for older Retrotinks or the Framemeister, but I have seen people struggling with the signal swapping delay and video output of the Framemeister as it is old tech now.Not all is positive though, I found the customer support incredibly unhelpful. I don't believe English was the first language of person I was emailing, so I will go easy. I was getting a popping sound in the audio, and support E-mail reply I got was along the lines of "these are the common fixes, if it doesn't help, we won't offer any further support". I'm paraphrasing of course, but considering the fix had nothing to do with what they offered, I have very little trust in them to offer genuine support. I'll quickly run through some technical setup tips and problem fixes that I had in case it helps someone else. First off, PCIe has become far more complicated, so you might have speed problems based on the age and spec of your PC. PCIe has individual lanes that shares bandwidth when multiple devices are used. I would suggest not buying this if you don't have at least a gen 2 PCIe board, and even then, due to the bandwidth 4K uses, you might have issues if using less than Gen 3. Assuming your 16x lane is housing your GPU, you will probably be using the x8 lane for this card. This is important, because some motherboards will only allow either a M.2 NVME drive, or use of the PCIe slot not both. My point is, it's worth seriously looking into your motherboards specs and how you have configured it before you buy this as the 4x lane will probably be too slow for capturing 4K. Since buying this I have upgraded to an ASUS ROG x670 EXTREME motherboard, which is a top end £1k board paired with a Ryzen 9 7850x3d, if you have anything like this, this card will be no problem at all no matter how you configure it.My second point is related to the problem I was having with the audio cracking. Little embarrassing but make sure you are using good quality HDMI cables and I suggest not using a cable longer than 2m max. After I bought a high quality 4K cable, I realised there was a cable in the 4K Live Gamer box, so fool on me I suppose but it did fix the issue. I can confirm that long HDMI cables will lead to an unstable signal. For me, anything over 2M would cause the picture to keep dropping out.Regardless of the poor customer service, I still give this 5 stars as it really is a fantastic card. I had an Elgato 4K card and it was a nightmare, very picky about signals and cables, making it pretty much trash for what I wanted to use it for. So, in summary, if you are looking for a card that works great with OSSC and Retrotink 5x, this is a must buy over anything Elgato offers. I haven't tested it with modern consoles like PS5 and Xbox series X, but I really can't see it having any issues as they are the modern standard of video signal.Just to be clear, I am using this with a RTX4090, but I was using it in my backup rig with a 2080 Super, and it works just as good rendering a 4K capture. I cannot speak to the compatibility with AMD or Intel GPU's.Hope this helps.
