Abstract: The present disclosure relates to methods and apparatus of operation of a GPU. The apparatus can determine a plurality of attributes including one or more vertex attributes and one or more instance attributes. The apparatus can also send the plurality of attributes to at least one processing unit. Additionally, the apparatus can store at least one of the plurality of attributes in a buffer of the at least one processing unit. In some aspects, the at least one of the plurality of attributes can include the one or more instance attributes. The apparatus can also retrieve the at least one of the plurality of attributes from the buffer when the at least one of the plurality of attributes is stored in the buffer. Also, the apparatus can store at least some of the plurality of attributes in a cache of the at least one processing unit.

Abstract: The present disclosure relates to methods and apparatus for graphics processing. In some aspects, the apparatus can determine a plurality of sub-primitives corresponding to one or more primitives in an image. The apparatus can also determine visibility information for each of the sub-primitives. The visibility information can include information regarding whether the sub-primitive is visible. Further, the apparatus can identify one or more of the sub-primitives as visible based on the visibility information. The apparatus can also determine a sub-primitive visibility stream including the sub-primitives identified as visible. Additionally, the apparatus can render at least one of the sub-primitives identified as visible in the sub-primitive visibility stream. The apparatus can also identify at least one of the sub-primitives as not visible based on the determined visibility information. Moreover, the apparatus can determine to skip rendering the at least one of the sub-primitives identified as not visible.
