Motion Blur shenanigans or Hardware problems?

Hi! Downloaded UE 5.7 (its my dream to make games, and i waited for fresh engine version to start).
But the second i start Intro-project to learn, by eyes start bleeding. Insane motion blur plus possibly artifacts? I thought it’s only motion blur and lumen to blame, but i actually remembered that i had similar problems even with motion blur off in games like No Man’s Sky.

I understand motion blur, but where does fingers go on screenshot? And why borders of the shadow and objects are so bad? Maybe it’s problems with hardware?

My setup is: Ryzen 3600, RX 6600, 32GB of DDR4 3200. Latest drivers everywhere.

Found the answer on 3rd party chat (faster than official forum, lol)
Problem was:

  1. Motion blur
  2. Clipping hands into camera
  3. Lumen
  4. 1 pixel text (not 3d) caused visual problems with text.

Also fun fact. Launching this Intro project in full-game mode, all text broke into squares
