P3D Rilasciato Prepar3D 5.2

Corposo e inatteso aggiornamento di Prepar3D alla versione 5.2


"The changelog is fairly extensive, with a lot of focus on the Enhanced Atmospherics engine and lighting. According to the changelog, Enhanced Atmospherics can be used with legacy clouds, along with improvements to memory usage, precipitation and lighting. In addition, they have also addressed how clouds in EA are rendered (less of a gird effect) and several other improvements that have been reported since version 5.1.

Whilst the update is focused on the environmental effects, there has also been additional improvements to road light settings, and particles can now be dynamically lit. Virtual Reality has also seen numerous improvements, whilst support for headsets has been extended to include the VRgineers XTAL VR and the Varjo XR-3 VR headset."
