That hybrid setup is where “better” truly happens.
It bypasses the Windows graphical overhead, offering lower latency and better CUDA performance. tcc wddm better
Let’s break down what each mode does, where they excel, and why “TCC + WDDM better” is the wrong framing. In reality, it’s , depending on your workload. That hybrid setup is where “better” truly happens
Recent benchmarks and developer discussions suggest that WDDM can make RAM-to-GPU data transfers significantly slower—sometimes by orders of magnitude—due to "block swapping" and OS management. Switching to TCC can yield performance parity with Linux, which lacks the WDDM bottleneck. Extended Execution: where they excel
Download NVIDIA CUDA Toolkit (includes nvidia-smi ). Step 2: Open Command Prompt as Administrator. Step 3: Check current mode:
