For problem 1 I would recommend looking into Vulkan Memory Allocator: https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator The general idea is to allocate large chunks of memory, then sub-allocate out of those when buffers are required. This is nice for several reasons: - Memory allocation can be slow and involve system calls. Sub-allocating does not require system calls - Your memory will be more cache-friendly as all your buffers will be relatively adjacent - There is a finite number of unique allocations you can have. Performing larger allocations keeps your usage lower
