The Apple 5K retina is 5120‑by‑2880 pixels
So we start off with a number that is too small
#define SCREEN_MEMORY_SIZE_4K (4096*2160*4) //~33,7 mb
and then divide it by 2
#define MAX_POOL_MEMORY SCREEN_MEMORY_SIZE_4K/2
and I have no idea what a typical size is for
self.device.recommendedMaxWorkingSetSize
which we are also dividing by 2.
So I have no idea what the logic is behind all these numbers.
