    Abstract: A method for cloud gaming. The method including generating a plurality of video frames when executing a video game at a cloud gaming server. The method including encoding the plurality of video frames at an encoder bit rate, wherein the plurality of video frames that is compressed is transmitted to a client from a streamer of the cloud gaming server. The method including measuring a maximum receive bandwidth of a client. The method including monitoring the encoding of the plurality of video frames at the streamer. The method including dynamically tuning a parameter of the encoder based on the monitoring of the encoding.

    IPC: G06T15/00

    Abstract: A method including rendering graphics for an application using graphics processing units (GPUs). The method including dividing responsibility for processing pieces of geometry of an image frame during an analysis pre-pass phase of rendering between the plurality of GPUs, wherein each of the pieces of geometry is assigned to a corresponding GPU. The method including determining in the analysis pre-pass phase overlap of each of the pieces of geometry with each screen regions. The method including generating information at the GPUs regarding the pieces of geometry and their relations to the screen regions based on the overlap of each of the pieces of geometry with each of the screen regions. The method including assigning the screen regions to the GPUs based on the information for purposes of rendering the pieces of geometry during a subsequent phase of rendering.

    CPC classification number: G06T1/20

    Abstract: A method for graphics processing. The method including rendering graphics for an application using a plurality of graphics processing units (GPUs). The method including dividing responsibility for the rendering geometry of the graphics between the plurality of GPUs based on a plurality of screen regions, each GPU having a corresponding division of the responsibility which is known to the plurality of GPUs. The method including generating information regarding a piece of geometry with respect to a first screen region for which a first GPU has a first division of responsibility, while rendering the piece of geometry at a second GPU for an image. The method including rendering the piece of geometry at the first GPU using the information.

    Abstract: A method for encoding including executing game logic built on a game engine of a video game at a cloud gaming server to generate video frames. The method including executing scene change logic to predict a scene change in the video frames based on game state collected during execution of the game logic. The method including identifying a range of video frames that is predicted to include the scene change. The method including generating a scene change hint using the scene change logic, wherein the scene change hint identifies the range of video frames, wherein the range of video frames includes a first video frame. The method including delivering the first video frame to an encoder. The method including sending the scene change hint from the scene change logic to the encoder. The method including encoding the first video frame as an I-frame based on the scene change hint.
