Apparently the latest WHQL driver, 418.81, can cause random application crashes and TDRs (“Timeout Detection and Recovery”) issues on Windows 7 and 8.1. NVIDIA has followed up with a hotfix driver, 418.99, that addresses the issue.

Hotfix drivers do not undergo full testing, so they should not be installed unless you are concerned about the specific issues they fix. In this case, because the bug does not affect Windows 10, a Windows 10 driver is not even provided.

In case you’re wondering what “Timeout Detection and Recovery” is, Windows monitors the graphics driver to make sure that work is being completed quickly (unless it is not driving a monitor – Windows doesn’t care how long a GPU is crunching on compute tasks if it is not being used for graphics). If it hangs for a significant time, Windows reboots the graphics driver just in case it was stuck in, for example, an infinite loop caused by a bad shader or compute task. Without TDR, the only way to get out of this situation would be to cut power to the system.
