Short description of error
So essentially Blender 2.80 AND 2.81 crashes when I switched to rendered viewport mode using Cycles, after modifying the material on my object. Material(tab)->Settings->Surface->Displacement(Displacement and Bump)

Exact steps for others to reproduce the error
I'm going through a tutorial (Blender Guru's Beginner tutorial for 2.8 video level 2 part 4: Procedural displacement) so it has several steps. I don't remember it all, however, i'm going to go ahead and attach the actual blend file and to be able to reproduce the problem from the blend file, make sure the renderer is set to cycles, with sample size of 32 for both render and viewport. Then simply make sure Dispacement and Bump is set on the material tab as outlined above. And select "Rendered" viewport shading. It should start to render in cycles and go for a bit and then after less than a minute it should crash.

Here is the texture should be in the same folder/directory as the blend file

AS A QUICK UPDATE: It appears that if in the shading tab you change the scale in the displacement node from 1 to something really small like 0.001 it doesn't crash then. So presumably scale of 1 caused some super massive geometry that kills the GPU. In fact it won't crash in CPU mode.
