    Abstract: A system, method, and computer program product are provided for shading primitive fragments. A target buffer may be recast when shaded samples that are covered by a primitive fragment are generated at a first shading rate using a first sampling mode, the shaded samples are stored in the target buffer that is associated with the first sampling mode and the first shading rate, a second sampling mode is determined, and the target buffer is associated with the second sampling mode. A sampling mode and/or shading rate may be changed for a primitive. A primitive fragment that is associated with a first sampling mode and a first shading rate is received and a second sampling mode is determined for the primitive fragment. Shaded samples corresponding to the primitive fragment are generated, at a second shading rate, using the second sampling mode and the shaded samples are stored in a target buffer.

    Abstract: A system, method, and computer program product are provided for using a bit-count texture format. A rasterized coverage bit mask is received by a texture processing unit from a bit-count format texture map, the rasterized coverage bit mask is converted to a scalar value, and the scalar value is processed while the rasterized coverage bit mask is retained in the bit-count format texture map. The coverage bit mask may be converted by computing a count of samples that are covered by at least one graphics primitive according to the rasterized coverage bit mask.

    Abstract: Embodiments of the present invention provide a novel solution which can be used to detect and analyze instances of micro stutter within a given game, GPU and/or driver version. Embodiments of the present invention may be operable to divide an application session into a set of sub-sessions and perform multiple derivative calculations on time-varying application parameters (e.g., frame rates) measured during each sub-session. Embodiments of the present invention may also be operable to generate separate histograms for each derivative calculation performed. As such, based on calculations performed, embodiments of the present invention may synchronously increment histogram bins representing a corresponding range of performance in real-time. Upon the completion of the application session, sub-session histograms may be compressed and then saved into a log which can be fetched and uploaded to a host computer system for aggregation and storage into a database for server-side optimization analysis.

    Abstract: In various embodiments, a parallel processor implements a graphics processing pipeline that generates rendered images. In operation, the parallel processor causes execution threads to execute a task shading program on an input mesh to generate a task shader output specifying a mesh shader count. The parallel processor then generates mesh shader identifiers, where the total number of the mesh shader identifiers equals the mesh shader count. For each mesh shader identifier, the parallel processor invokes a mesh shader based on the mesh shader identifier and the task shader output to generate geometry associated with the mesh shader identifier. Subsequently, the parallel processor performs operations on the geometries associated with the mesh shader identifiers to generate a rendered image. Advantageously, unlike conventional graphics processing pipelines, the performance of the graphics processing pipeline is not limited by a primitive distributor.
