Windows Timeout Detection and Recovery overview

The Timeout Detection and Recovery (TDR) feature within Windows serves to determine if the Graphics Processing Unit (GPU) has frozen during a specific graphics operation. Once that determination is made, the TDR will then reset the graphics driver to prevent having to fully reboot the computer. TDR is most often used during periods of intensive graphical operations, such as during video editing or game play.

The default timeout period used by the TDR feature is set to 2 seconds. If the GPU (Graphical Processing Unit) cannot complete the current task within that time period, then Windows determines that the GPU is frozen and uses TDR to restart the video driver. The screen will flicker to show the recovery is in progress and the screen will redraw.

Potential issues and errors with Windows Timeout Detection and Recovery

To prevent Timeout Detection and Recovery from occurring, hardware vendors should ensure that graphics operations take no more than 2 seconds for certain graphics-intensive scenarios (video editing, productivity applications, game play). If the hardware is not designed to meet this specification, then the TDR feature will report issues with the specific graphics-intensive process and recover the graphics driver before the process can complete.

An indication that this is the case will appear within the Windows Event Viewer. For instance, multiple instances of the warning event ID 4101 appear stating that the "Display driver nvlddmkm stopped responding and has successfully recovered" if there are timeout issues with an nVidia graphics driver.

Using the Windows Registry to change Timeout Detection and Recovery Settings

The settings within the Timeout Detection and Recovery feature can be modified within the Windows Registry to help in troubleshooting specific TDR issues. For example, the default time for detection can be changed to a longer period than 2 seconds. Or the TDR feature, itself, can be disabled.
