Reaching the advertised 4K144 capture spec depends entirely on forcing MJPEG encoding, which offloads heavy decompression to the host CPU — real-time performance depends on the receiving computer's decoding power. No native HDCP bypass; manual HDCP disable is required on PS4/PS5. When mic-in and headset-out ports are both occupied, the controller silently mutes any headset-mounted microphone in favor of the dedicated MIC IN jack.
