This. There is an article by Michael Abrash that goes into good detail about this: http://blogs.valvesoftware.com/abrash/when-it-comes-to-resolution-its-all-relative/ http://blogs.valvesoftware.com/abrash/when-it-comes-to-resol... quoted: "Given which, the obvious question is: how high does VR resolution need to go before it’s good enough? I don’t know what would be ideal, but getting to parity with monitors in terms of pixel density seems like a reasonable target. Given a 90-degree field of view in both directions, 4K-by-4K resolution would be close to achieving that, and 8K-by-8K would exceed it."
