Unless I've completely misunderstood the way viewer handles texture load, textures further away and/or smaller on the field of view are given a lower priority, which leaves them rendered at a significantly lower resolution, which under normal circumstances is fine; it makes no sense to render a 1K and especially 2K texture at the full resolution if the face it's on only the size of a postage stamp on your screen, but the trouble is with animated textures (specifically using LOOP) which only ever show a small segment of the full texture area at a time, even when camming right into them they might never show at the full resolution, so there probably should some kind of an accommodation made for animated textures to give them a priority when rendering a scene.
