Abstract

A system for modifying one or more shader configurations, the system comprising an application executing unit configured to execute an application using a first shader configuration, a performance monitoring unit configured to obtain performance data from one or more performance counters associated with a GPU used to execute the application, and a parameter modification unit configured to modify the first shader configuration in dependence upon the obtained performance data to obtain a modified shader configuration, wherein the application executing unit is configured to execute the application using the modified shader configuration as the first shader configuration, and wherein the performance monitoring unit and the parameter modification unit are configured to repeat their respective functions in an iterative manner until a termination condition is met.

First claim

1 . A system for modifying one or more shader configurations, the system comprising:
an application executing unit configured to execute an application using a first shader configuration; a performance monitoring unit configured to obtain performance data from one or more performance counters associated with a GPU used to execute the application; and a parameter modification unit configured to modify the first shader configuration in dependence upon the performance data to obtain a modified shader configuration, wherein the application executing unit is configured to execute the application using the modified shader configuration as the first shader configuration, and wherein the performance monitoring unit and the parameter modification unit are configured to repeat their respective functions in an iterative manner until a termination condition is met.

2 . The system of claim 1 , wherein the application is a video game.

3 . The system of claim 1 , wherein the performance monitoring unit is configured to obtain performance data during a rendering of a plurality of frames of image content output by the application.

4 . The system of claim 1 , wherein the performance monitoring unit is configured to obtain performance data over a plurality of passes.

5 . The system of claim 4 , wherein each of the plurality of passes is associated with data obtained for a different set of performance metrics.

6 . The system of claim 1 , wherein the parameter modification unit is configured to modify the first shader configuration by selecting one or more alternative shaders and/or modify one or more shader parameters associated with the first shader configuration.

7 . The system of claim 1 , wherein the parameter modification unit is configured to modify one or more aspects of the first shader configuration in dependence upon a random factor.

8 . The system of claim 1 , wherein the parameter modification unit is configured to modify one or more aspects of the first shader configuration in dependence upon a convergence model.

9 . The system of claim 1 , wherein the parameter modification unit is configured to modify one or more aspects of the first shader configuration in dependence upon a predefined mapping between performance data and modifications.

10 . The system of claim 1 , wherein the termination condition is one or more of:
a predefined number of iterations of a modification process; successive iterations of the modification process providing a below-threshold degree of modification; an input by a user of the application; a threshold period of time having elapsed; a predetermined segment of the application ending; and/or obtained performance data, or changes in the performance data relative to performance data of a preceding iteration, meeting particular thresholds.

11 . The system of claim 1 ,
wherein the performance monitoring unit is configured to obtain performance data during execution of the application outside of a modification process, and wherein the system is configured to restart the modification process in response to obtained performance data meeting one or more predetermined conditions.

12 . The system of claim 1 , wherein the system is configured to restart a modification process in response to an initiation of a new segment of the application.

13 . A method for modifying one or more shader configurations, the method comprising:
executing an application using a first shader configuration; obtaining performance data from one or more performance counters associated with a GPU used to execute the application; modifying the first shader configuration in dependence upon the performance data to obtain a modified shader configuration; and execute the application using the modified shader configuration as the first shader configuration, wherein the method is implemented in an iterative manner until a termination condition is met.

14 . The method of claim 13 , wherein the application is a video game.

15 . The method of claim 13 , wherein the performance data is obtained during a rendering of a plurality of frames of image content output by the application.

16 . The method of claim 13 , wherein the termination condition is one or more of:
a predefined number of iterations of a modification process; successive iterations of the modification process providing a below-threshold degree of modification; an input by a user of the application; a threshold period of time having elapsed; a predetermined segment of the application ending; and/or obtained performance data, or changes in the performance data relative to performance data of a preceding iteration, meeting particular thresholds.

17 . A non-transitory machine-readable storage medium which stores computer software which, when executed by a computer, causes the computer to perform a method for modifying one or more shader configurations, the method comprising:
executing an application using a first shader configuration; obtaining performance data from one or more performance counters associated with a GPU used to execute the application; modifying the first shader configuration in dependence upon the performance data to obtain a modified shader configuration; and execute the application using the modified shader configuration as the first shader configuration, wherein the method is implemented in an iterative manner until a termination condition is met.

18 . The non-transitory machine-readable storage medium of claim 17 , wherein the application is a video game.

19 . The non-transitory machine-readable storage medium of claim 17 , wherein the performance data is obtained during a rendering of a plurality of frames of image content output by the application.

20 . The non-transitory machine-readable storage medium of claim 17 , wherein the termination condition is one or more of:
a predefined number of iterations of a modification process; successive iterations of the modification process providing a below-threshold degree of modification; an input by a user of the application; a threshold period of time having elapsed; a predetermined segment of the application ending; and/or obtained performance data, or changes in the performance data relative to performance data of a preceding iteration, meeting particular thresholds.
