Tcc Wddm Better -

If your GPU supports TCC and you're serious about compute performance on Windows, the choice is clear — TCC mode is the better option. Switch today and stop letting WDDM hold your GPU back.

: Prevents "Display driver stopped responding" (TDR) errors during long-running AI or simulation tasks.

You can check and toggle your driver modes using the NVIDIA System Management Interface ( nvidia-smi ) via the Windows Command Prompt (run as Administrator). nvidia-smi --query-gpu=index,name,driver_model --format=csv Use code with caution. tcc wddm better

如果您使用的是支持的硬件，切换模式是一个简单直接的过程，仅需管理员权限和一次重启。

Display Support: WDDM is required if you want to plug a monitor into your GPU. If your GPU supports TCC and you're serious

you control the entire graphics pipeline, need microsecond-level timing, and run a dedicated display task. Choose WDDM if you need Windows compatibility, dynamic workloads, or GPU sharing across processes.

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.

NVIDIA has acknowledged that MCDM submission latency is currently higher than TCC but is . This suggests MCDM could eventually become the ideal driver model for all GPUs on Windows.
