The gpu_mem option in config.txt specifies how much memory, in megabytes, to reserve for the exclusive use of the GPU: the remaining memory is allocated to the ARM CPU for use by the OS.
You can take a test and observe for a period of time.
Hi @Cris Zhan-MSFT ,
Thanks for the response. I know Windows IoT Core does not use the GPU for hardware acceleration. Our interface does not use heavy animations or video but shows some controls and mainly images.
Is gpu_mem used for displaying images on the screen and does it technically make sense to increase the gpu_mem in case of showing more images on the screen?
