It includes a HEVC encoder which works well for capturing and recording... but it doesn't function properly for streaming since you can't stream HEVC alone without X264. This makes it unsuitable for Twitch streaming. It likely supports X264 too, but at much lower quality due to high bitrates that Twitch restricts. I understand your concern—probably it won't handle 165Hz even with an adapter. You might also be spending too much on a capture card; if you can stream smoothly at 1440p 165Hz, you shouldn’t face performance problems. That card supports 720p, 1080p and 2160p at 60Hz, but not higher resolutions or high refresh rates. On a PC, you may see screen tearing because FPS won't match the capture's refresh rate. This isn't an issue with software-based capture using CPU or GPU. Latency appears to be another major problem.
I'm not entirely confident about what I meant to say, but I believe I saw a reference to something that supports 1080p at 240Hz. I thought I read it could handle 1080p at 240Hz. Now I'm thinking about it from the basics (starting with an average device with 35ms latency). Which one can get an HDMI or DP connection at 165Hz for 1440p? The goal is to keep the input stable so I don't have to adjust my monitor's refresh rate or disable G-Sync. I hope this will work best, mirroring the monitor to that device.
In the video review linked, he mentioned it can't support 1440p. This person frequently tests 1440p using capture cards because it's a common resolution many users employ. I suggest reviewing his posts for any capture card you're interested in—he does a lot of them. He also talks about Adaptive-Sync in some of them, though I don't recall the details since I haven't paid much attention to it.
Streamers who play Twitch often experience delays of 5 to 30 seconds due to processing. For those using Jackbox or multiplayer setups, Discord is a common choice for live streaming. Version 2.0 performs quite well. Compared to onboard encoding devices, NVENC delivers much faster encoding. If you achieve solid image quality, you’ll still lag a few seconds because of the time needed. You’ll need to compromise on some aspects. Accepting around 1% loss in FPS for better picture quality is acceptable. Use your GPU for encoding and switch to Discord or similar platforms for streaming. Creating smooth, high-quality live video demands significant GPU power. Essentially, you’re aiming to build a game streaming service—just sacrifice some sharpness and performance to get there. Or upgrade your hardware and rely on a stable internet connection.
You can simply connect an HDMI cable to your GPU and use Elgato to mirror the screen. This may cause slightly lower performance compared to using your GPU directly for encoding and streaming. Remember, the Elgato still requires your computer to encode and transmit the video. It won’t handle everything on its own. Stick with your PC’s native encoder for better results. Then share your stream at 1080p60 with friends—this ensures a smooth, high-quality experience without unnecessary strain.
For minimal cost and reduced latency, set up an OBS with an RTMP server on the PC you plan to stream from. This way, you host directly and avoid delays from third-party tools.
