Retraced rotation render delay - 7-25 WIP

I think I remember a thread about this fairly recently, but can’t find it. Anyway, it’s still happening:

When rotating a raytraced image there is a several second delay before the (shaded?) temporary image appears. This is very annoying and off-putting. Is this already logged?

My video card is a Nvidia k4000.

It is reported and on my list.
