I have made a funky cube with displace modifier with around 100 000 vertices, and blender suddenly takes around a minute or more just to change between edit and object mode, when saving, or going back(Ctrl + Z).
Screenshot of the object:
I noticed that when this freeze happens, my pc only uses 1 core of the processor to the fullest, and not the rest(16 cores).
i have AMD Ryzen 2700, 16gb ram, AMD Radeon R9
Is there any way to make it faster?
