Even after 20-40 minutes of the launcher opened and running, it still used 50% or over of my PCU clock cycles.  I can't see a reason for it.  It also slows down my game and the whole PC.  When I close it, Raid performs well.

Note:  

• I upgraded from Plarium Play website download to Windows store.  
• I have reinstalled everything Plarium related at least two times.  
• I have only Raid - Shadow Legends in my library.  
• I am using a 1-core AMD APU FX+ and a Geforce 1050-ti.
