Ray tracing requires OpenGL 4.0+ or OpenGL 3.3+ with GL_ARB_texture_buffer_object_rgb32 extension. Textures within ray tracing will be available only when GL_ARB_bindless_texture extension is provided by driver. On mobile platforms, OpenGL ES 2.0+ is required for 3D viewer (OpenGL ES 3.1+ is recommended). The ray tracing is not yet available on mobile platforms. Some old hardware might be unable to execute complex GLSL programs (e.g. with high number of light sources, clipping planes). OCCT 3D Viewer, in general, supports wide range of graphics hardware - from very old to new. Therefore, if you observe some unexpected visual issues - first check for OpenGL driver update (or firmware update in case of mobile platforms); but beware that driver update might also come with new bugs. Don't forget to report these bugs to vendors.
