So you are saying that 90s is a remarkable improvement?
I would expect a huge difference in the usefulness of a simulated nose, depending on the content. In a roller coaster the movement of your head (rotation) and the movement of the carriage (translation) are separate and clearly defined this way. You control the Rotation while the game controls the translation. I don’t know what this villa demo is, but depending on how the movement is controlled, an unintuitive and unnatural system is bound to make almost everyone nauseous.
