VMA

A common approach for carving big GPU memory allocations into many smaller pieces efficiently.

Vulkan makes you manage GPU memory yourself, and asking the driver for memory one object at a time is slow and wasteful. The Vulkan Memory Allocator (VMA) pattern grabs large blocks and suballocates them into the many small buffers and images an app needs, handling alignment and reuse. It's the standard way to avoid hand-rolling GPU memory management.
