Vulkan is an explicit API, enabling direct control over how GPUs actually work.
As such, Vulkan supports systems that have multiple GPUs, each running with a different driver, or ICD (Installable Client Driver).
Vulkan also supports multiple global contexts (instances, in Vulkan terminology).
The ICD loader is a library that is placed between a Vulkan application and any number of Vulkan drivers, in order to support multiple drivers and the instance-level functionality that works across these drivers.
Additionally, the loader manages inserting Vulkan layer libraries, such as validation layers, between an application and the drivers.
Updates to the `Vulkan-Loader` repository which correspond to a new Vulkan specification release are tagged using the following format: `v<`_`version`_`>` (e.g., `v1.1.96`).
**Note**: Marked version releases have undergone thorough testing but do not imply the same quality level as SDK tags. SDK tags follow the `sdk-<`_`version`_`>.<`_`patch`_`>` format (e.g., `sdk-1.1.92.0`).
This scheme was adopted following the 1.1.96 Vulkan specification release.
