(If you see "WDDM" – you are in slow mode)
You cannot turn on TCC mode on every NVIDIA graphics card. NVIDIA uses this feature differentiation to separate consumer hardware from enterprise hardware.
To understand why "TCC WDDM better" is a valid search, you must understand the bottleneck. WDDM was built for Windows Vista and refined through Windows 11. Its primary job is to virtualize the GPU so that 100 different applications can all draw to the screen simultaneously.
If you’re convinced TCC is better, here is how to enable it. tcc wddm better
Look for the or Driver Mode section in the output. Step 2: Switch to TCC Mode To change the GPU at index 0 to TCC mode, execute: nvidia-smi -g 0 -dm 1 Use code with caution. (Note: -dm 1 sets the mode to TCC). Step 3: Switch back to WDDM Mode
If your work involves CUDA, AI training, or any workload where milliseconds matter and crashes are unacceptable, switching to TCC isn't just a preference—it is a professional necessity. For the compute user, TCC represents the unshackling of the GPU from the burdens of the GUI.

In practice, this gives you:
You can remote into a Windows Server 2019/2022 instance from a MacBook, run nvidia-smi , and see your A100 screaming at full throttle. WDDM cannot do this without a dummy plug (a physical HDMI fake monitor).

No display. No DirectX. No OpenGL hardware acceleration for remote desktop.
(and essential) if your computer doubles as a daily driver, or if your creative work involves DirectX/OpenGL applications, real-time viewport manipulation, or video playback.
TCC模式专为计算集群节点设计，将GPU转化为一个纯粹的计算设备。在这一模式下，GPU完全专注于GPGPU计算，不再作为显示适配器使用。 WDDM was built for Windows Vista and refined
