Hello,

You can run PVRTune to collect GPU statistics. You can find the tool and documentation here:

I can't use tool for some reasons, I want the data to be displayed directly on the screen. The data can be displayed in the follow picture, why I can't in my board?

Hello,

I would recommend downloading the PSDK RTOS and referencing the code for the Vision Apps demos to draw usage on to the display.

The load data displayed on that screen you shared has been gathered using the api defined in vision_apps/utils/perf_stats/include/app_perf_stats.h. And the boxes are draw using the api defined in vision_apps/utils/grpx/include/app_grpx.h.

Regards,

Takuma
