Abstract: A system includes a video source device connected to a video destination device via a network. The video source device includes a network interface and an encoder coupled to the network interface. The encoder is configured to encode a first stream of rendered video frames having a first frame rate to generate a second stream of encoded video frames for transmission over the network via the network interface, wherein the second stream has a second frame rate greater than the first frame rate. As part of this encoding process, the encoder is configured to selectively encode multiple instances of at least one video frame of the first stream for inclusion in the second stream to compensate for the difference between the first frame rate and the second frame rate.

Abstract: A server executing an application generates a frame token for a frame that is rendered for the application. One or more first metric messages are provided to the application in response to at least one first operation performed by the server on the frame. The first metric messages include the frame token and information indicating timing of the at least one first operation. The encoded information representing the frame token and the frame is transmitted from the server towards a client. One or more second metric messages are provided to the application in response to one or more second operations performed by the client on the frame. The one or more second metric messages include the frame token and information indicating timing of the second operations. A state of the application is modified based on the first and second metric messages.

Abstract: A game streaming system encodes a raw frame to generate an encoded frame for a game stream including a plurality of frames for display. The system identifies a first encoding artifact based on a first difference between the encoded frame and the raw frame, and applies an overlay to the encoded frame. The overlay includes a first visual indicator indicating the first encoding artifact.

Abstract: One or more hardware components identify a bottleneck stage within a processor pipeline that processes frames of a video stream. The bottleneck stage has a first clock. An upstream stage receives a feedback signal from the bottleneck stage. The upstream stage has a second clock and the feedback signal includes information as to time required by the bottleneck stage to operate on data and information as to time the data spent queued. The upstream stage adjusts the speed at which the upstream stage operates and queues data to approximate the speed at which the bottleneck stage is operating and queuing data.

Abstract: A method and computer program product are provided for generating a shader program. Included is a file associated with a graphics effect. In use, a shader program is generated based on processing of the file to apply the graphics effect to an object.

Abstract: A graphics system has a mode of operation in which real samples and virtual samples are generated for anti-aliasing pixels. Each virtual sample identifies a set of real samples associated with a common primitive that covers a virtual sample location within a pixel. The virtual samples provide additional coverage information that may be used to adjust the weights of real samples.

Abstract: A graphics processor performs culling of invisible primitives in a vertex processing unit that includes a geometry shader or other processing engine that performs per-primitive operations. Primitives can be culled after clip space coordinates for the vertices have been computed and in some instances before at least one other vertex attribute has been computed. To the extent that this early culling reduces the number of vertices for which the full set of attributes is computed or reduces the number of primitives or vertices delivered to downstream units, throughput of the processor is increased.
