Abstract: A method for graphics processing including rendering graphics for an application using a plurality of graphics processing units (GPUs). The method including dividing responsibility for rendering geometry of the graphics between the GPUs based on screen regions, each GPU having a corresponding division of the responsibility which is known to the GPUs. The method including determining a Z-value for a piece of geometry during a pre-pass phase of rendering at a first GPU for an image, wherein the piece of geometry overlaps a first screen region for which the first GPU has a division of responsibility. The method including comparing the Z-value against a Z-buffer value for the piece of geometry. The method including generating information including a result of the comparing the Z-value against the Z-buffer value for use by the GPU when rendering the piece of geometry during a full render phase of rendering.

Abstract: A method of cloud gaming is disclosed. The method including receiving an encoded video frame at a client, wherein a server executes an application to generate a rendered video frame which is then encoded at an encoder at the server as the encoded video frame, wherein the encoded video frame includes one or more encoded slices that are compressed. The method including decoding the one or more encoded slices at a decoder of the client to generate one or more decoded slices. The method including rendering the one or more decoded slices for display at the client. The method including begin displaying the one or more decoded slices that are rendered before fully receiving the one or more encoded slices at the client.

Abstract: A method for cloud gaming. The method including generating a video frame when executing a video game at a server. The method including scanning-in the video frame to an encoder at the server scanline-by-scanline. The method including encoding one or more encoder slices as one or more encoded slices at the encoder, wherein each encoded slice is delivered to a buffer at an encoder fill rate. The method including draining a first encoded slice from the buffer to stream the first encoded slice at a buffer drain rate over a network to a client, wherein the first encoded slice is streamed over the network before fully encoding the one or more slices of the video frame.

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.
