Dynamic refresh rate (DRR) switching is used to dynamically update a refresh rate of content presented on an interface. When a first application and a second application are presented on a user interface at a first refresh rate; a request may be received to temporarily boost the first refresh rate to a second, higher, refresh rate. DRR switching is initiated as the first refresh rate is temporarily boosted to a second refresh rate. Applications that are opted in to the second refresh rate receive signals to refresh content at the second refresh rate, while applications that are not opted in to the second refresh rate receive signals to refresh content at a virtualized refresh rate that matches the first refresh rate. Thus, the first application refreshes content at the first refresh rate and the second application refreshes content at the second, higher refresh rate, providing a smooth user experience without unnecessarily utilizing power consumption.

Dynamic refresh rate switching system and method thereof

Dynamic refresh rate switching

To manage dynamic adjustment of the refresh rate of a computer display, the operating system defines at least two playback modes: one or more custom modes that can be selected by applications, and a standard mode which is a default setting for the system that can be expected by applications. The operating system provides an application programming interface that enables an application to request using a custom mode. If approved to use the custom mode, then the application presents frames for display based on the custom mode. The operating system stores timing data for each buffered frame indicating how to play the frame in both standard mode and the custom mode. If a transition back to the standard mode occurs, the operating system uses the timing data to properly present frames of video until the application stops generating frames of video in the custom mode.

Managing transitions of adaptive display rates for different video playback scenarios

Transitions between monitor configurations may be streamlined by minimizing the tearing down and recreating of render targets and primary frame buffers associated with the monitors. In at least one example, the techniques described herein include identifying at least one render target in a first monitor configuration that is also in a second monitor configuration. In response to identifying the at least one render target in the first monitor configuration that is also in the second monitor configuration, the techniques herein describe maintaining the at least one render target during a transition between the first monitor configuration to second monitor configuration.
