Low Res Iray Preview

Any idea why my iray preview does this intermittently? Scenes are posed in texture shaded, or other non iray preview mode then when switching to iray, the preview mode goes very low res randomly (example1). It is also usually accompnied by the veiwport camera (any camera) going off track when trying to zoom. Clicking in an empty part of the scene, reframing the active camera, then zooming in and out seems to fix the issue (example2), but its a right pain.

    The bolded part gives me an idea. Open the Draw Settings tab and take a look there (while your Iray preview viewport is active). You can adjust how sensitive the Iray preview is to view changes before it decides to redraw and/or how long it waits for you to stop moving before it goes back to normal.
