    Abstract: A method for executing a game by a computing system that uses a central processing unit (CPU) and graphics processing unit (GPU) for generating video frames. A draw call is generated for a video frame by the CPU. At bind time, i.e. writing of the GPU commands by the CPU using a GPU API, asset aware data (AAD) is written to the command buffer, and loading of one or more level of detail (LOD) data from an asset store to system memory is requested. The GPU executes the draw call for the frame using LOD data written to the system memory, the GPU using at least a minimum of LOD data based on the AAD. Additionally, the GPU uses information regarding the LOD load state when executing the draw call, in order to avoid access to LODs not yet loaded.

    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.

    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.

    Abstract: A method for cloud gaming. The method including generating a video frame when executing a video game at a server. The method including performing a scan-out process by scanning the video frame scanline-by-scanline and one or more user interface features scanline-by-scanline to one or more input frame buffers, and compositing and blending the video frame and the one or more user interface features into a modified video frame. The method including scanning in the scan-out process the modified video frame to an encoder at the server scanline-by-scanline. The method including beginning in the scan-out process scanning the video frame and the one or more user interface features to the one or more input frame buffers at a corresponding flip-time for the video frame.
