The only instance I can see this is if a game requires a new Vulkan extension, which wouldn't need a new kernel but would need a new Mesa version to provide that extension. For the most part, games use established and standardized APIs (OpenGL, Vulkan, Direct3D) to utilize the GPU and as long as the driver implements the APIs used by the game, the driver doesn't need to continuously update in order to support game updates. On Linux, the driver doesn't handle Direct3D anyways and an intermediate layer (DXVK or VKD3D) is used to translate Direct3D API calls into the Vulkan API. Vulkan does support extensions which are added every so often to provide new interfaces and the userspace portion of the driver (which is responsible for compiling/translating Vulkan API calls into raw GPU instructions) needs to be updated to support these, but also sometimes these extensions are optional and games can use less optimized code paths to work around missing extensions.
Ah I see, thanks for the info.
