With the Graphics Frame Analyzer, you can test your OpenGL/OpenGL ES* frames against a remote Ubuntu* target system.
To connect a remote Ubuntu* system for analysis:
Use the Texture 2x2 override mode to help identify potential performance bottlenecks caused by texture maps used in your application. All textures for a scene are replaced with four different colors for each pixel.
If using this override mode significantly improves the frame rate, this is an indicator that the application is texture bound. The common ways to fix this issue are:
Intel GPA provides the following command-line tools on Ubuntu* OS:
Specify the target Android* device.
Use this option to specify the name of your Android* target device. You can skip this option if you have only one device connected to your analysis system.
The VS EU Stall metric shows the percentage of time during which the execution units (EUs) were stalled in the vertex shader.
