Additionally, execution of the plurality of subject commands may be deferred until one or more additional commands referencing the common screen location are executed. In one example, the plurality of subject commands are serialized in response to a serialization command. ## Claims ### Claim 1 A system to present visual content, comprising: a display to output visual content based on pixel data; a serialization module to identify a plurality of subject commands that reference a common screen location and access a read/write resource; a command order module to serialize the plurality of subject commands according to a predefined order; and an thread order module to defer execution of the plurality of subject commands until one or more additional commands referencing the common screen location are executed, wherein execution of the plurality of subject commands and the one or more additional commands generates the pixel data. ### Claim 2 (depends on 1) The system of claim 1, wherein the plurality of subject commands are to be serialized in response to a serialization command. ### Claim 3 (depends on 2) The system of claim 2, wherein the serialization module is to read the serialization command in one of a High Level Shading Language or an OPENGL Shading Language. ### Claim 4 (depends on 1) The system of claim 1, wherein the command order module is to determine the predefined order based on a rasterization order of incoming primitives associated with the plurality of subject commands. ### Claim 5 (depends on 1) The system of claim 1, wherein the plurality of subject commands are to be associated with a first pixel shader thread and the one or more additional commands are to be associated with a second pixel shader thread. ### Claim 6 (depends on 1) The system of claim 1, wherein the plurality of subject commands are to reference one of a DIRECTX unordered access view or an OPENGL image. ### Claim 7 A method of processing commands, comprising: identifying a plurality of subject commands that reference a common screen location and access a read/write resource; serializing the plurality of subject commands according to a predefined order; and deferring execution of the plurality of subject commands until one or more additional commands referencing the common screen location are executed. ### Claim 8 (depends on 7) The method of claim 7, wherein the plurality of subject commands are serialized in response to a serialization command. ### Claim 9 (depends on 8) The method of claim 8, further including reading the serialization command in one of a High Level Shading Language or an OPENGL Shading Language. ### Claim 10 (depends on 7) The method of claim 7, further including determining the predefined order based on a rasterization order of incoming primitives associated with the plurality of subject commands. ### Claim 11 (depends on 7) The method of claim 7, wherein the plurality of subject commands are associated with a first pixel shader thread and the one or more additional commands are associated with a second pixel shader thread. ### Claim 12 (depends on 7) The method of claim 7, wherein the plurality of subject commands reference one of a DIRECTX unordered access view or an OPENGL image. ### Claim 13 At least one computer readable storage medium comprising a set of instructions which, if executed by a computing device, cause the computing device to: identify a plurality of subject commands that reference a common screen location and access a read/write resource; serialize the plurality of subject commands according to a predefined order; and defer execution of the plurality of subject commands until one or more additional commands referencing the common screen location are executed. ### Claim 14 (depends on 13) The at least one computer readable storage medium of claim 13, wherein the plurality of subject commands are to be serialized in response to a serialization command. ### Claim 15 (depends on 14) The at least one computer readable storage medium of claim 14, wherein the instructions, if executed, cause a computing device to read the serialization command in one of a High Level Shading Language or an OPENGL Shading Language. ### Claim 16 (depends on 13) The at least one computer readable storage medium of claim 13, wherein the instructions, if executed, cause a computing device to determine the predefined order based on a rasterization order of incoming primitives associated with the plurality of subject commands. ### Claim 17 (depends on 13) The at least one computer readable storage medium of claim 13, wherein the plurality of subject commands are to be associated with a first pixel shader thread and the one or more additional commands are to be associated with a second pixel shader thread. ### Claim 18 (depends on 13) The at least one computer readable storage medium of claim 13, wherein the plurality of subject commands are to reference one of a DIRECTX unordered access view or an OPENGL image. ### Claim 19 An apparatus to process commands, comprising: a serialization module to identify a plurality of subject commands that reference a common screen location and access a read/write resource; a command order module to serialize the plurality of subject commands according to a predefined order; and a thread order module to defer execution of the plurality of subject commands until one or more additional commands referencing the common screen location are executed. ### Claim 20 (depends on 19) The apparatus of claim 19, wherein the plurality of subject commands are to be serialized in response to a serialization command. ### Claim 21 (depends on 20) The apparatus of claim 20, wherein the serialization module is to read the serialization command in one of a High Level Shading Language or an OPENGL Shading Language. ### Claim 22 (depends on 19) The apparatus of claim 19, wherein the command order module is to determine the predefined order based on a rasterization order of incoming primitives associated with the plurality of subject commands. ### Claim 23 (depends on 19) The apparatus of claim 19, wherein the plurality of subject commands are to be associated with a first pixel shader thread and the one or more additional commands are to be associated with a second pixel shader thread. ### Claim 24 (depends on 19) The apparatus of claim 19, wherein the plurality of subject commands are to reference one of a DIRECTX unordered access view or an OPENGL image.
