Microsoft Edge
Override for the CPU performance tier
Supported on Microsoft Edge version 149, Windows 7 or later
What it does
This policy allows you to override the value returned by the CPU Performance API (that is, navigator.cpuPerformance). If you enable this policy, the value of navigator.cpuPerformance is overridden with the specified value. If you don’t configure this policy, the default performance tier calculation is used. You can specify a value from 0 through 4. For more information, see https://github.com/WICG/cpu-performance.

- The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
- Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
- The generated payload is incomplete because one or more ADMX element values were not supplied: CpuPerformanceTierOverride
