How long does your PC take to "compile shaders" for UE4 Cave Particle Map

mine I think is taking 8 minutes I think.

Athlon 760K 4 GHZ Quad Core CPU


Radeon HD 7850 1GB video card.

YOu guys know the first time you download that map from the market place its stuck on compiling shaders for like a while?

How long does yours take and whats your PC specs? I upgraded my PC recently to these specs for UE4 development. I had a Pentium G3220 dual core haswell.
I should note all 4 of my cores stick to 100% max usage I assume compiling and rendering uses all the powers of a CPU hence the only situation where AMD can shine? where a software is heavily multi threaded?

It doesn’t really compile shaders at first download, I just tried as I though that seemed strange.

What about an i5 9400F 2.9Ghz?
