is the default driver mode for the vast majority of NVIDIA GPUs. It allows the GPU to be used for both display output and GPGPU computing, balancing resources between showing your desktop and running CUDA workloads. However, this convenience comes at a cost. The Windows operating system inserts itself as a middleman, batching and scheduling GPU work to maintain display responsiveness — which can introduce significant overhead for compute-intensive applications.
If you’re convinced TCC is better, here is how to enable it.
Under WDDM, every time your Python script (TensorFlow/PyTorch) wants to launch a kernel on the GPU, the Windows Kernel must:
: Standard RDP often fails to leverage a WDDM-based GPU for compute tasks. TCC mode ensures the GPU remains fully available to remote users and cluster management systems. 4. How to Switch to TCC Mode
The GPU bypasses the Windows graphics subsystem entirely, communicating directly with the hardware layer.
TCC mode bypasses the standard Windows graphics stack, significantly reducing kernel launch overhead and driver latency.
