weird editor lag

I’m using ue4 since years, it worked well in my Core i3 8100, 24gb ram, no discrete gpu.

  • but, to solve this issue UE4 crashing at importing Var 10 of any 3dplant from bridge – Quixel
    i was updated graphics drivers and changed power plan from High Performance to Balanced, and then Balanced to High Performance and also resetted to power plan defaults,
    now ue4 editor lagging like a hell,
    ue4 using 60%+ cpu while loading editor and then always using less than 2% cpu.

  • disabled use less cpu in background, enable high dpi support, but no use.
    there are no background applications using high cpu, cpu usage is at 5%.

  • Tried Scan Hardware in Dell Support Assist, it will do Stress Test, in this test All are maxed out, no issues, pc working well.

  • Why UE 4.27.2 using only 2% cpu?
    Windows 10 22H2, OS Build: 19045.2006
