OpenGL message "lost connection"

I have seen this Event Log Message:

The NVIDIA OpenGL driver lost connection with the display driver due to exceeding the Windows Time-Out limit and is unable to continue.

The application must close.

What does it mean?

If you received this message from an application (on a pop up message or in the Event Log), the application was unable to continue rendering because the Microsoft Windows imposed time limit (TDR) was exceeded. This is normally the case when the workload sent to the Graphics Card is greater than what the graphics card can process in the normal timeout of two seconds.

You can find more information in this page:

How can this be fixed?

Two possible solutions to try would be:

  1. Reduce the graphics workload if possible, such as rendering to a lower resolution or with less detail.
  2. Increase the timeout to allow more time to complete the really tough rendering parts. Microsoft provides the information on how to modify the Windows Registry to achieve this.
