Recommended Posts

V4.5hotfixblack

Prepar3D V4.5 was released a few weeks back, which brought a range of improvements to the simulator. Today, Lockheed Martin has released Hotfix 1 for Prepar3D V4.5 (4.5.12.30293). The hotfix addresses numerous community reported problems such as performance issues, an issue with a crash during re-enabling of Virtual Reality and also an error with PBR textures when first entering a vehicle.

As per the instructions on the Prepar3D website, you first must uninstall the current Prepar3D V4 client via Programs and Features in Windows Control Panel. You can then download the Client installer via your downloads section. Whilst the fixes for the hotfix are found mostly in the client download, you may also want t0 download Content and Scenery installers also for those fixes. If you’d prefer, you can also download a full version of Prepar3D V4.5.

For more information please view the Prepar3D v4 Download and Installation Directions.

It should be noted that some developers may require an update to their product before you will be able to use it correctly with the new update installed. Please use caution when updating before reading if your products will work with version P3D V4.5.12.30293.

You can read the full post over on the Prepar3D blog post. Additionally, you may want to read our interview with Lockheed Martin’s Adam Breed as part of our Developer Month series.
