Is there a way to turn off the incremental rendering, so it only updates the viewport once the render is finished?
I'm using the "render preview" in 3D viewport, with eevee. When I rotate the view with the mouse, it is very jerky, because of the incremental render. I don't mean it's slow between frames: my scene is small and quick to draw. What I mean is that it first draws a very coarse version of the scene, then fills in details over two or three more screen refreshes. It is still quick, but the interleaved coarsely rendered frames really makes it hard on the eyes when you rotate the view.
