Hi,

Was curious if increasing the gpu_mem in config.txt has any effect on Windows IoT Core and my UWP app?!

    Hi,

    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.
    https://www.raspberrypi.org/documentation/configuration/config-txt/memory.md

    You can take a test and observe for a period of time.

    Hi @Cris Zhan-MSFT ,

    Did test and observe it already for a period of time but wanted to know from a technical perspective if it would make any sense to increase the gpu_mem. Is it being used by Windows IoT Core or am I just reserving memory which is never used?

    Best, Dick
