Iray viewer speed

Chenova

Hi guys!

Does anyone know of a way to speed up the iray previewer? This is particularly a problem when I'm designing a character and need to change facial sliders often (as facial features often look different in iray I have to preview each feature change). It usually takes around 10-15 seconds depending on if I have nothing else showing (hiding hair etc). Maybe this is normal?

If I’m building a scene including trees, lighting, building etc, the previewer is even slower, perhaps taking 30secs or more.

These are my PC specs in case they’re relevant: AMD Ryzen 7 2700X Eight-Core Processor (16 CPUs), ~3.7GHz, 16384MB RAM, 64bit, NVIDIA GeForce GTX 1070 Ti

Thanks in advance! :)

Speed up rendering, or speed up the switch to the preview instead of the smooth shaded view? The former can be controlled with the Draw Settings pane, I'm not sure there's anything to be done about the latter.
