CRASH: Raytracing with Landscape Element

Hardware

  • Ryzen 9 7900X
  • 64 GB DDR 5 RAM
  • AMD Radeon RX 7800 XT w/ 16GB Video RAM

Problem
With my configuration Path Tracing is no problem - even with complicated reflections, many objects in scene etc. But after placing a single landscape plane, the instance path tracing is enabled, the program freezes the whole screen with only the mouse still working. After a while even the mouse stops and only a freezed screen remains until a hard reboot.

I have no real Idea why this could be and what to change other than buying a new graphics card.
