It usually occurs when the application attempts to send a command to the GPU—such as drawing a frame or allocating memory—and the hardware fails to respond or returns an "Invalid Argument" or "Device Removed" signal. This is often tied to DirectX Raytracing (DXR) or complex shader computations that overwhelm the driver. Common Culprits Several factors typically converge to trigger this crash: Driver Instability
