CPU and GPU levels

Updated: Jul 28, 2026
Your app can provide hints to increase or decrease the CPU and GPU clock speeds on Meta Quest headsets at runtime. Higher clock speeds increase power consumption, so these controls let you trade battery life for performance.
Rather than request clock frequencies directly, your app can suggest a range of CPU and GPU levels, from PowerSavings to Boost. This abstraction supports multiple chipsets and lets apps receive performance boosts (such as the 7% GPU boost for GPU level 4 in v49 OS) without rebuilding.
Select the lowest CPU and GPU levels that allow your application to run consistently at framerate.

Profiling CPU and GPU level and frequencies

You can profile current CPU and GPU level, frequency, and utilization using the OVRMetrics Tool, the Performance Analyzer section of Meta Quest Developer Hub, or the VrApi log stats.

In this image, MQDH is used to profile an application running on Quest 2 at CPU level 4 / 1.478GHz, and GPU level 3 / 490MHz.

Setting CPU and GPU levels

Set CPU and GPU levels using the ProcessorPerformanceLevel enum, exposed through these engine-specific functions:
EngineFunction
Unreal
UOculusXRFunctionLibrary::SetSuggestedCpuAndGpuPerformanceLevels (exposed in Blueprint)
Unity
OVRPlugin::suggestedCpuPerfLevel, OVRPlugin::suggestedGpuPerfLevel
Native
ovrp_SetSuggestedCpuPerformanceLevel, ovrp_SetSuggestedGpuPerformanceLevel
Spatial SDK
spatial.setPerformanceLevel
Rather than setting a specific CPU or GPU level, you select a ProcessorPerformanceLevel. The OS dynamically adjusts levels within a range, staying as low as possible while maintaining framerate. This automatically extends battery life during less-demanding scenes.
CPU and GPU level ranges can also change based on enabled features. For instance, Meta Quest 3 and Meta Quest 3S devices cannot access GPU levels 3 or 4 when passthrough is enabled. Refer to each headset’s “CPU/GPU level availability” section and Boosting CPU and GPU Levels for details.

Spatial SDK defaults to SustainedHigh. Prior to 0.7.0, the default was SustainedLow. This improves app performance at the cost of battery life.
*The SustainedHigh CPU level range can be increased, depending on the headset and enabled systems. See Boosting CPU and GPU Levels for details.

**CPU ProcessorPerformanceLevel Boost provides the same CPU level range as SustainedHigh. However, during short periods of time when Boost is available, it sets the CPU level to 8.
For more details, including when Boost is available, see CPU Boost Hint.

If possible, CPU level will increase when CPU utilization is 83% or greater, and decrease when CPU utilization is 77% or lesser.
Note: CPU and GPU levels above 4 were introduced after the Meta Quest 1 end-of-life.
Note: Although the Meta Quest 1 has a higher clock speed on its application cores than the Meta Quest 2, it uses a simpler CPU architecture. Internal tests on VR applications found that Meta Quest 2's CPU architecture allowed it to run 80% more instructions per cycle.
