Improved Volumetric Cloud Rendering

The Prepar3D v5.3 update is packed with numerous performance, visual, and usability improvements. Updates to weather systems including optimized cloud and terrain blending, dynamic lighting on precipitation, improved sun and moon lighting, and better fog visuals make training in difficult conditions and locations even more immersive. Performance has been improved across the whole platform including areas with dense content, traffic, and weather rendering. Additionally a vast amount of default content including buildings, landmarks, and airport vehicles have been updated to PBR textures.

Atmospherics and PBR Improvements

New development features including clear coat support, additive PBR materials, PBR support for autogen annotation, and multiple improvements to sloped airport creation give developers even more tools to create high quality content. Additionally the in-application Development menu has been expanded adding additional tools and features designed to streamline content development and testing including access to the Visual FX and Traffic Toolbox tools within the application and real-time HTML5 content debugging with webkit inspector views.

Please be aware that unlike previous version updates both content and scenery are required to be updated with version 5.3. Completely uninstalling the previous verions and running the full installer is recommended.

The following list of updates has been categorized based on the installer required. The Client, Content, and Scenery installers are required for Prepar3D v5.3, however the SDK installer is optional. You must first have Prepar3D v5 installed to utilize the Client only installer.

To install the Prepar3D v5.3 Client, you must first uninstall the previous Prepar3D v5.0/v5.1/v5.2 Client through Programs and Features in Windows Control Panel. Do not deactivate your license when prompted. If you selected to deactivate your license during uninstallation of your current Client, your will be prompted to reactivate Prepar3D. Please view the Prepar3D v5 Download and Installation Instructions for more information.
