Hello. I began to discover the Blender 2.8 (used 2.7 sometime before). And get in stuck with this problem. My geometry, a little bit more complex than simple, give me 120 seconds to wait when I put a modifier on it.
I don't know. I think this more than normal priority to fix.
What we have for real. We can not do any high poly modelling now. Right?
Maybe we can see the previous version of this modifier if it is so hard to make it quick with new?
