Slow Problem on MB-LAB

Hi

I use 2.81 Version for Blender, before when i start to launch screen to Blender, it’s work normally speed also after when i press the Preferences to click on Add-Ons then i press install to find MB-Lab-1_7_8.zip, after it’s on already so i press Create character before it’s work normally with Method to display/shade objects in the 3D view: Solid, and after when i press the Method to display/shade objects in the 3D view: Material Preview, problem is something gone wrong about the speed are not good enough, i don’t even understand what’s the problem system for MB-LAB are too slow, i have no idea how gonna to fix problem speed?

Maybe MB-LAB is more highest GHz or it’s differents?

My: Windows 10 Professional 64-Bits
My: AMD FX ™-6100 Six-Core Processor 3,30 GHz

And i’m sorry my bad english!
