Interactive rendering subsampling

[Ludvik Koutny]

IR is still terribly slow in some shading-heavy scenes in terms of navigation in scene, compared to VrayRT or Octane. It takes quite a while for entire screen to redraw even at very small resolutions, so one can not fluidly navigate scene to pick view angle. It works well for teapots (or cars) on a plane, but breaks when for example navigating inside of a forest scene with many translucent leaves with opacity. One has to wait several seconds after ever view movement to see where camera moved.

Yes, I had the same "problem" with heavy interior rendering. +1

Is there a way to have realtime feedback with the interactiv rendering? I have a dell workstation bi xeon E5 and I have to wait 1or 2 sec between each action.
Thank you
