Symptoms
Affected Products:
- Dell Optimizer
Affected Versions:
- v1.0
- v.3.0 and Later
Cause
Optimize Applications Machine Learning (ML) models added in DO v1.0 (and removed in DO v4.2.1) were deemed obsolete given the generation over generation chipset technology advances and software application architecture changes. Recent testing revealed that the ML models were not yielding the desired optimizations when they were first released.
Prioritize Foreground Applications (In DO v3.0 and later) on Windows 11 provides no additional benefit beyond what Windows 11 natively provides. Enabling the feature may even add greater degradation to background applications without providing any additional benefit to foreground applications.
Resolution
Turning off all optimization features in the Applications pane restores application performance.
