If you have ever installed an NVIDIA professional GPU (Quadro, Tesla, A100, RTX A-series) and opened NVIDIA SMI (System Management Interface) only to see the cryptic flags TCC or WDDM next to your driver type, you have likely asked one question:
Enable TCC on your compute GPU (e.g., GPU 0):
For 90% of serious compute workloads—deep learning, AI training, CUDA development, and high-performance computing (HPC)—the answer is a definitive .
nvidia-smi -g 0 -dm 1 (0 = WDDM, 1 = TCC)
nvidia-smi -q | findstr "Driver Model" (If you see "WDDM" – you are in slow mode)
