Let’s dig into what the Vulkan Runtime actually does , and why its architecture is the secret sauce behind modern high-performance rendering. The promise was "low driver overhead." Many heard "no driver." Wrong.

Beyond the Driver: Deconstructing the Vulkan Runtime and Why It’s More Than Just a “Driver Replacement”

And without a , the runtime will recompile your PSO (Pipeline State Object) every single time you run your app. That’s seconds of stutter.

The reality is far more complex, and far more powerful. The —that background process you see in Task Manager ( VulkanRT or vulkaninfo.exe )—is not the driver. It is a user-mode intermediary that fundamentally changes the contract between your application and the silicon.
