preview in mat.editor

Hello to all!
Thanks for forum!
---
I wanna ask how do i control quality of preview in mat.editor?
I know about quality-checkbutton and sliders, additionally spread of threads. So if i decrease to minimal, anyway got slow response from renderer's preview(without displacement in mat).

Well...Overall with displacement the render of the material is slower.

You can set the correct slidebar to the 24% and you will can make an idea of your material. Only if you are gonna make a "macro" type render it's recommended to wait till the material preview render finish...I don't do that ever.

It's one of the disadvantages of a render engine like Fryrender or Maxwell.

Regards.

thank you!

Unfortunately you have to work making "an idea", an "approaching" to your desired result related to mateirals and their preview renders...Or if you have an eight core microprocessor or being more realist a four core microprocessor... You won't need waiting for too much. Not all of us can have a four cores...By now... Ah ah ah...

Regards.
