Test plan
PBR terrain should work on Windows with Intel integrated graphics, without crashing.
To be extra thorough, try the following advanced settings combinations, and confirm none of them cause a crash:
RenderTerrainPBRDetail
: 0, -1, -2, -3, or -4RenderMaxOpenGLVersion
: If your testing computer supports a higher OpenGL version, try setting this value down to 4.4 instead, restart the viewer, and continue testing
