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

Independent refresh rates may be enabled for multiple monitors. Any displays that are presenting content in a full screen mode are refreshed at a rate set by the application presenting the content. All other devices are refreshed at a rate that is determined by a window manager based on various factors including the type of application(s) executing, the size of the applications presenting content, the location of the applications presenting content, hardware configurations, and so forth.

Independent refresh rate for multiple monitors

Virtual surface techniques are described. These techniques support the use of initialization and batching of updates, use of updates and lookaside lists, use of gutters, blending and BLT operations, use of surface optimization techniques such as push down as well as enumeration and clumping, mesh usage, and use of occlusion management techniques.

Virtual surface blending and BLT operations

Virtual surface update and composition techniques are described. These techniques include support of initialization and batching of updates, use of updates and lookaside lists, use of gutters, blending and BLT operations, surface optimization techniques such as push down as well as enumeration and clumping, mesh usage, and occlusion management techniques.

Virtual surface compaction

Virtual surface gutters

Composition system thread techniques are described. In one or more implementations, a composition system may be configured to compose visual elements received from applications on a thread that is executed separately than a user interface thread of the applications. As such, the composition system may execute asynchronously from a user interface thread of the application. Additionally, the composition system may be configured to expose one or more application programming interfaces (APIs) that are accessible to the applications. The APIs may be used for constructing a tree of objects representing the operations that are to be performed to compose one or more bitmaps. Further, these operations may be controlled by several API visual properties to allow applications to animate content within their windows and use disparate technologies to rasterize such content.

Composition system thread

Shared compositional resources are described. In one or more implementations, a global composition system may be configured to perform rendering for a plurality of processes, e.g., applications. For example, the global composition system may be configured to expose one or more application programming interfaces (APIs) that are accessible to the processes. The APIs may then be used to cause a single composition engine to perform the rendering for the plurality of applications. Thus, the single composition engine may be leveraged to support a variety of functionality, such as to manage sharing of compositional resources by a plurality of processes. This sharing may be performed in a variety of ways, which may include use of a writer/reader paradigm.

Shared compositional resources

Techniques for an input object for routing input for visual elements are described. In at least some embodiments, a region of a display area includes multiple graphic elements that can be generated and/or managed by different graphics functionalities. For instance, a graphical user interface (GUI) for an application can include a primary window and visual elements within the primary window, such as banners, control buttons, menus, Tillable fields, and so forth. In at least some embodiments, the primary window of the GUI can be managed by a first graphics functionality, while one or more visual elements within the primary window can be managed by a second graphics functionality. In accordance with one or more embodiments, an input object is employed to route input to visual elements to a graphics functionality responsible for managing the visual elements.

The APIs may then be used to cause a single composition engine to perform the rendering for the plurality of applications. The use of a single composition engine may be used to support a variety of different functionality, such as to perform efficient rendering by knowing what elements are provided by each of the applications and how those items relate for rendering to a display device.

Virtual surface techniques are described. These techniques include support of initialization and batching of updates, use of updates and lookaside lists, the use of gutters, the use of blending and BLT operations, surface optimization techniques such as push down as well as enumeration and clumping, mesh usage, and occlusion management techniques.

Display techniques using virtual surface allocation

A technique for generating content for a stereo 3D display buffer having both stereo 3D graphic objects and non-stereo 3D graphic objects that may be utilized to render stereo 3D content onto one or more windows of a display. The technique incorporates content from stereo 3D application frame buffers into a composition tree that represents the graphic objects in each window displayed on a computing device. At each refresh cycle, the composition tree is traversed to generate content for a stereo 3D display buffer that is then used to draw one or more windows onto a display.
