Abstract: A system disclosed within this document is capable of improving performance in virtual computing environments, e.g., by reducing latency associated with streaming video data between a client device and an associated server system over a network. As discussed in detail below, such performance improvements can be achieved using techniques that avoid, reduce and/or overlap operations that are executed by the server system in order to render, encode, and/or transmit video data to a client device over a network. Such techniques can be used to reduce propagation and/or processing delays imposed by, for example, the server system's CPU operations, input/output (I/O), infrastructure, NIC, OS processes, among other types of hardware and software-based overheads. In various implementations, the performance enhancements can be realized at the rendering, encoding, or transmission operations performed by the server system.

Abstract: In some implementations, a system is capable of reducing latencies associated with streaming virtual reality (VR) content over a virtualized computing environment. A first frame of VR content provided to a computing device is identified. A second frame of the VR content to be rendered for display on the computing device is also identified. Input data associated with the VR content streamed on the computing device is obtained. A collection of partial frames associated with the first frame is determined. One or more partial frames is selected from among the collection of partial frames that are associated with the first frame. An instruction for rendering the second frame is generated. The instruction includes at least, for each of the selected partial frames, a representation of the difference between a corresponding portion of the first frame and a particular partial frame. The instruction is provided to the computing device.
