I was very exited to play the demo but when start driving i got these major shadow or Light glitches. The Landscape and the Car flickers in dark shapes or Shadows and its really anoying and not enjoyalbe. I tried to update my GPU, cpu, windows and atleast reinstall it on a different HDD/SDD nothing changed.
I know its the highest possible settings and dont even reach 60fps but i also tried with lower settings and the shapes dont disappear.
I hope the Full Game is fixed at the release.
