Why do I have 26 percent CPU load when everything is paused?

Question

Hi,

I have a project which is a vehicle dashboard. when all the objects are frozen and no movement is sensed CPU load is 26 percent. what does the CPU do?

Answer 1

Hi,

please note, that the main loop is still active and running even there are no updates necessary on the screen.

The high CPU load can be caused by your device drivers, when you are processing data from your underlying API. Can you exclude your device drivers and check if the CPU load goes down?

Maybe you have some timers active in your GUI application that do some calculation.

Best regards,

Manfred.

it's somehow weird. when I have a lot of pictures, the CPU load is high. when I remove pictures and objects CPU load downs to zero.

Can you provide an example that shows the issue?
