I am working on an animation fly-over of moving data. To perfect it, I am making lots of small changes to my keyframes. My Preview and eventual export are very different from the Scene (See below). When I make a change, such as adjusting the camera's heading, it takes 15-20 seconds for the preview to reload or sync (I've timed it). This is killing my productivity. In the Preview's Image Details, I see the Display Rendering Quality is set to "high". Is there a way to change that to fast?
