| [UnknownPerformanceLevel](/engine/6000.7/script-reference/unityengine/adaptiveperformance/constants/unknownperformancelevel.md)   | UnknownPerformanceLevel is the value of [IDevicePerformanceControl.GpuLevel](/engine/6000.7/script-reference/unityengine/adaptiveperformance/ideviceperformancecontrol/gpulevel.md), [PerformanceMetrics.CurrentGpuLevel](/engine/6000.7/script-reference/unityengine/adaptiveperformance/performancemetrics/currentgpulevel.md), [IDevicePerformanceControl.CpuLevel](/engine/6000.7/script-reference/unityengine/adaptiveperformance/ideviceperformancecontrol/cpulevel.md), and [PerformanceMetrics.CurrentCpuLevel](/engine/6000.7/script-reference/unityengine/adaptiveperformance/performancemetrics/currentcpulevel.md) if the current performance level is unknown. This can happen when AdaptivePerformance is not supported or when the device is in throttling state (see [WarningLevel.Throttling](/engine/6000.7/script-reference/unityengine/adaptiveperformance/warninglevel/throttling.md)). |
