Picframe runs hot and uses significant CPU on the Raspberry Pi 5. #392

Closed bobburgers7 closed 5 months ago

bobburgers7 commented 5 months ago

I've been running picframe on my RPI5 and noticed it runs very hot (85.6 C). I checked and see that the picframe process is stressing the CPU: 370%. Conferring with sapnho, it doesn't appear that's normal when running on the RPI4 where it uses 2-3%.

I am running:

Linux pi5 6.6.31+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.6.31-1+rpt1 (2024-05-29) aarch64 picframe Version: 2024.5.31

I also used py-spy and saw the below

could it be due to the difference in the GPU from VideoCore VI to VideoCore VII? I think VI is 32 bit and VII is 64 bit and drivers are probably less mature and thus causes the work to be offloaded to the CPU?
