Why does the GPU version appear unstable on my Windows machine?

If your older or lower-powered GPU or iGPU appears to be unstable on your Windows operating system in StarTools, and you think it may be struggling with any larger datasets you give it, then the issue may be caused an unsuitable Timeout Detection and Recovery (TDR) allowance.

TDR is a feature that is meant to prevent GPU "hangs". If a task "hangs" the GPU for longer than 2 seconds, the TDR kicks in and will reset the GPU driver.

This Windows default behaviour is not suited for compute-heavy tasks as found in StarTools. Fortunately, it can be corrected by making modifications to the default 2 second timeout value.
