12ms puts it at about 90hz latency. I play games on a 144hz screen, and I can tell the difference between 90 and 144 hz, and that's on a bad screen at an arms length from my face that's definitely not trying to convince me I'm looking at reality.

It'll probably be in the same ballpark as a good transparency mode on headphones -- close to indistinguishable in small bursts, but long term causes alienation/lack of presence.
