Idea - How to get fast head tracking with any frame rate
Here's an idea of how to get low latency head tracking with almost any variable frame rate. Render the scene from the player's point of view with no distortion, but to a larger render target with a...
The only problem that it doesn't really work because you get perspective messed up even for a simple head rotation motion, not to mention for any linear motion, in-game or Rift's. It also cost too much.
Carmack proposes that it's possible to do a rendering update by shifting pixels depending on most recent readings and pixels' world coordinates. He also says that using simple black pixels for the pixels that "were" off-screen works surprisingly well and you don't need to render extra padding for this.
