Is it normal for the memory usage of the Vulkan demo in the Textured3DCubeSession to be three times higher than the OpenGL demo?

The memory usage of Textured3DCubeSession On my Huawei Mate60 phone:
Vulkan, GL Memory : 334M

But the OpenGLES3.0 GL Memory only : 97M

@vinsentli You can set the parameter VulkanContextConfig::vmaPreferredLargeHeapBlockSize to 16Mb to reduce the amount of memory preallocated for VMA pools. 2a63241
