Elgato Game Capture 4K60 S+ features a powerful H.264/HEVC video encoder which is needed to compress the 4K60 HDR video into a data rate that can be sent over USB 3.0 to a computer or recorded directly onto a SD card without a computer. Compressing the video adds a small amount of latency to the 4K60 S+ when connected to a PC via USB 3.0.
Elgato Game Capture 4K60 S+ has a delay of around 200ms. This number can vary based on the sources resolution, frame rate and setups.
Other audio and video sources in streaming applications must be delayed by around 200ms to match the gameplay video and audio of the Elgato Game Capture 4K60 S+.
