The reason the render resolution is so high is warping. You're rendering a flat image per eye at said resolution, you then need to warp this to a geometry corresponding to the Q2's optics. An analogy is wrapping a vinyl print on a mug; in order to have something that looks right in perspective, and is even in resolution, you need a much larger image. Maybe not a great analogy but you get what I mean - you want the same perceived resolution across the whole image and this ups your flat render.
