(Windows Display Driver Model) is Microsoft’s graphics driver architecture introduced with Windows Vista and refined through every subsequent version (WDDM 2.0 with Windows 10, 2.1, 2.7, 3.0, etc.). It is the default, universal standard for all consumer GPUs (GeForce, Radeon, Intel iGPUs) and most enterprise GPUs.
(Tesla Compute Cluster) is a special driver mode developed by NVIDIA for its data-center and professional GPU lines (Tesla, Quadro, RTX A-series, and some high-end GeForce cards with modifications). In TCC mode, the GPU bypasses most of the Windows graphics stack and is treated as a pure, headless compute accelerator. tcc wddm
This is essential for the consumer experience. Because Windows itself is a graphical interface, the OS must ensure that the desktop, your web browser, and your video game can all coexist without crashing the system. If a GPU task hangs, WDDM can detect it, reset the driver (the famous "Display driver stopped responding and has recovered" message), and keep the computer running. In TCC mode, the GPU bypasses most of
