Error

For certain crashes, there may be a Windows event log message: A TDR has been detected. The Application must close. 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 two seconds. For more information: NVIDIA Support.
