    We're running out of VRAM and build is crashing on an iPad Pro 9.7. Looking at graphicsMemorySize it only has 512mb of available VRAM and we're targeting 1gb minimum.

    Is there any resource to find out which devices have what amount of VRAM?

    just to elaborate - there is NO VRAM on mobiles (they have shared memory so the same memory is used by cpu and gpu). Unity's graphicsMemorySize tries to estimate this: essentially it returns TotalMemory / 4.
    Also, apple does not allow appstore limiting by memory size AFAIK so you need to handle this situation (running on device with not much memory)

    Great this is good to know. You're right, we were crashing due to exceeding general memory usage. We'll detect general device memory and adapt. Thanks!
