Viewport very slow can't work with nodes

Question Lighting


I'm trying to do Fundamentals of materials and shading but the workflow becomes so slow that I'm barly able to use the nodes. I did reset to factory settings nothing helped. I've also tried different version 3.4 and 3.5.1 same problem. I have reduced undo steps to 32 didn't help. Render set to cycles Viewport 16 steps. No denoise selected. In my understanding it should work smooth without any problems. 

I also sure that my PC is strong enough to handle single object ligthing. 
- 1th Gen Intel(R) Core(TM) i5-11400F @ 2.60GHz 2.59 GHz
- 32 GB
- GeForce RTX 3060 (drivers upto date)

Any ideas?

    Computers being computers. The Matrix or Terminator will never happen and if it does, some glitch will make the machines go all crazy and reboot with a blue screen.
