Abstract: A method of tiled rendering is provided which comprises dividing a frame to be rendered, into a plurality of tiles, receiving commands to execute a plurality of subpasses of the tiles and interleaving execution of same subpasses of multiple tiles of the frame. Interleaving execution of same subpasses of multiple tiles comprises executing a previously ordered first subpass of a second tile between execution of the previously ordered first subpass of a first tile and execution of a subsequently ordered second subpass of the first tile. The interleaving is performed, for example, by executing the plurality of subpasses in an order different from the order in which the commands to execute the plurality of subpasses are stored and issued. Alternatively, interleaving is performed by executing one or more subpasses as skip operations such that the plurality of subpasses are executed in the same order.

Abstract: In one embodiment, a computing system may determine a focus point of a viewer based on received sensor data. The system may determine, for a current frame, a first viewing region encompassing a focus point of the viewer and a second view region excluding the first viewing region.

At least one second sampling resolution may be lower than a corresponding first sampling resolution associated with a same color channel. At least two of the second sampling resolutions for the color channels of the second viewing region may be different from each other. The system may output the color values for the first viewing region and the second viewing region of the current frame for display.
