The site has a new content architecture. We've added the ability to select your development device to show device-specific content. Please read our blog post Oculus Developer Center Update: Device-centric Documentation Architecture for more information.
All Oculus Quest developers MUST PASS the concept review prior to gaining publishing access to the Quest Store and additional resources. Submit a concept document for review as early in your Quest application development cycle as possible. For additional information and context, please see Submitting Your App to the Oculus Quest Store.
Sets the clock rates for the CPU and GPU on mobile devices.
Sets the clock rates for the CPU and GPU on mobile devices, as described in Power Management. For current hardware, the CPU and GPU levels can be set to 0, 1, 2, or 3. A value of 0 causes the CPU or GPU to operate at the slowest clock rate, which is most power efficient. A value of 3 causes the CPU or GPU to operate at the fastest clock rate, which produces the most heat and uses the most battery power.
Note that the Oculus Go provides a feature called Dynamic Clock Throttling, which treats the CPU and GPU levels as a baseline; the system can choose to dynamically increase the CPU and GPU clock rates based on application and system performance. For more information, see Power Management.
Mobile devices are typically constrained by the processing power of the device and its ability to dissipate heat.
To set your clock level in Unreal apps, use the SetCPUAndGPULevels blueprint.
On Oculus Go, we’ve made the management of CPU and GPU level much simpler by making it almost entirely automatic. This feature is called Dynamic Throttling. Oculus Go applications are compatible with Gear VR, and the basic power management API remains the same. The developer can set CPU and GPU levels between 0 and 3 on Gear VR, and between 0 and 4 on Oculus Go. On Go, these levels are treated as a baseline, and the system can choose to dynamically clock the CPU and GPU up as necessary to maintain performance. The goal of this system is to retain advantages of Gear VR’s Fixed Clock Policy while trying to mitigate its drawbacks.
