High CPU usage when 3D Graphics Applications are running

Ferhatx

Hi,

We are testing 3D Graphics performance for AM335X custom board with 4.3" LCD and

256MB DDR2 RAM. But we are suprised to usage of CPU.

When ChameleonMan is running, we see %95 CPU usage with top command.

When 3D Navigation is running, we see %98 CPU usage with top command.

But all SGX libraries are installed correctly. Could you clarify this issue? Why CPU usage

is much more high when upper 3D applications are running?

Best Regards,

Hi,

Any repy did not come to this question from E2E. But very low CPU usage are prouded when 3D Graphics core

is using by Silicon vendors. You can test with your EVM or starter kit with Matrix GUI for seeing High CPU Usage.

We are sure about all SGX libraries are installed correctly.

Ferhat,

have you tested it using the latest Linux SDK (5.06)?

The demos all run in a while loop. Hence you will see 100% CPU usage.
