Debugging a graphics application executing on a target device. The graphics application may execute CPU instructions to generate graphics commands to graphics hardware for generation of graphics on a display. A breakpoint for the graphics application may be detected at a first time. In response to detecting the breakpoint, one or more graphics commands which were executed by the graphics hardware proximate to the first time may be displayed. Additionally, source code corresponding to CPU instructions which generated the one or more graphics commands may be displayed.

Debugging a graphics application executing on a target device

Analyzing an application executing on a target device. An application may be executed on a target device. Low cost measurement may be gathered regarding the application executing on the target device. In response to a trigger, high cost measurement data may be gathered regarding the application executing on the target device. The high cost measurement data may include graphics commands provided by the application. The graphics commands and related information may be stored and provided to a host. The host may modify the graphics commands to perform experiments to determine performance issues of the application executing on the target device. The host may determine whether the performance is limited by the CPU or the GPU and may determine specific operations that are causing performance issues. The host may provide suggestions for overcoming the performance issues.
