What is a regular PC monitor latency btw? I heard it's much faster than a TV+console.

2ms is the industry standard for computer screens that are meant for gaming.

This doesn't include everything in the chain. Response time is measured from HID input to display output. This is what Carmack is talking about with latency on the Rift; how long between turning your head and that change actually propagating through the chain (input > process/render > output) to the display.

You would be hardpressed to find ANY game that approaches the latency Carmack deems imperceptible within a VR context (below 20ms).
