OpenGL “TDR detected” Meaning

Updated 09/29/2021 10:17 AM

What does the OpenGL "TDR detected" message mean?

I have seen this Event Log Message:

A TDR has been detected. The Application must close.

What does it mean?

If you received this message from an application (in the Event Log or on a pop up message), 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 alloted time of two seconds.

You can find more information on this page:

Timeout Detection and Recovery (TDR)

How can this be fixed?

Two possible solutions to try would be:

  1. Reduce the graphics workload if possible, such as by rendering to a lower resolution or by reducing the detail.
  2. Increase the timeout value to allow more time to complete more intensive rendering. Microsoft provides information on how to modify the Windows Registry to achieve this.
