Hi Jon,

Could you provide a little more information on how you are getting it to occur?

What steps are you taking to trigger the error?

Do you have any add-ons installed?

Please see the FAQs for some troubleshooting tips (http://www.prepar3d.com/frequently-asked-questions/):

Code: Select all

Prepar3D does not start, instantly shuts down, or does not perform as expected. What is wrong?

Ensure the proper graphics card is set to run Prepar3D. If an onboard video card (Intel HD) is told to run Prepar3D, these issues will likely occur. To correct, use the appropriate video card software to configure the graphic card’s control of Prepar3D. For NVIDIA graphics cards, open the NVIDIA Control Panel, select Manage 3D settings, and set the Preferred graphics processor to High-performance NVIDIA processor. You can also set Prepar3D.exe’s preferred graphics processor directly under the Program Settings tab under Manage 3D settings.

Often you might need to delete the following generated folders/files to have Prepar3D respect your changes. This will result in any add-ons being removed/disabled.
%PROGRAMDATA%\Lockheed Martin\Prepar3D v3
%LOCALAPPDATA%\Lockheed Martin\Prepar3D v3
%APPDATA%\Lockheed Martin\Prepar3D v3

Verify the fix was successful by opening Prepar3D and selecting Options, Settings, and under Full Screen Settings you should see the correct graphics card listed under Display.

Let us know,

It's a DX 11 event so I would think a hardware list should be provided?
Perhaps try to reinstall the latest driver for your GPU?
