    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: Performance of a legacy application may be characterized for subsequent adjustment of operating parameters when running the legacy application on a newer system. The legacy application is run on an older system and one or more key performance metrics that must be met when the legacy application is run on the newer system are determined along with other performance information useful for later adjustment of operating parameters of the newer system when running the legacy application on the newer system.

    Abstract: A graphics processing may include implementing a vertex shader and a pixel shader with a GPU. Vertex parameter values may be compressed with the vertex shader and compressed vertex parameter values may be written to a cache. The pixel shader may access the compressed vertex parameter values that were written to the cache and decompress the compressed vertex parameter values. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

    Abstract: Graphics processing may include implementing a vertex shader and a pixel shader with the GPU. Vertex indices output from a vertex shader may be written to a cache. The vertex indices written to the cache may be accessed with the pixel shader and vertex parameter values associated with the vertex indices may be accessed from a memory unit with the pixel shader.

    Abstract: A set of graphics primitive information for a virtual object may be processed with compute shader running on a graphics processing unit (GPU) to generate a modified set of primitive information. The modified set of primitive information may be passed to a vertex shader running on the GPU. The vertex shader may perform vertex shading on the modified set of primitive information.

    Abstract: Performance of a legacy application may be characterized for subsequent adjustment of operating parameters when running the legacy application on a new system. Performance information for the legacy application is recorded or derived while running the legacy application on the legacy system. One or more performance characteristics for the legacy application running on the legacy system are determined by analyzing the performance information, the one or more performance characteristics including one or more key performance metrics and other performance information. The one or more key performance metrics must be met when the legacy application is run on the new system. The other performance information is useful for later adjustment of operating parameters of the new system when running the legacy application on the new system.
