ippStsDllNotFoundBestUsed

This is a fallback warning from the dynamic dispatch path. The requested operation may still run, but not through the newest or most optimized processor-specific binary that the dispatcher tried to load.

The diagnostic question is performance and deployment completeness, not payload validity. Missing optimized DLLs or shared objects can silently shift execution to an older or more generic path.

Diagnostic focus

List the IPP domain libraries packaged with the application.
Compare performance against a known complete IPP installation.
Keep the warning visible because it may explain slower code without functional failure.
