My Cycles Rendering (F12) using CUDA (GTX1060 6Gb) and it works fine and fast - no problem!
But when I use View port (Shift+Z) - it use CPU (i7-7700K) only on 100 % ???
GPU load only at 5-12 % at the end of process
Why it happen?
My system: Windows 10 x64
Blender 2.79 ( 2.79.6 and 2.80 the same) All settings in Blender set to - GPU
Driver GPU is up to date.
In Performance settings (green line marked) there are options only about - CPU
Is that mean that View port (Shift+Z)use only - CPU?
Any idea about this?
May be it depend what is rendered? Some easy scene use GPU, but when it need to calculate very “hard” shaders, physics, particles so on…it allow to use only CPU???
P.S. After render in View port render (Shift+Z), when I trying to do something with my scene/objects/lights Blender is crushed. Helps only when disable that marks (red marked :) ) …maybe it will help to somewone
