For NVIDIA GPU users on Windows, the choice between TCC (Tesla Compute Cluster) WDDM (Windows Display Driver Model)

WDDM (Windows Display Driver Model): WDDM is a display driver model developed by Microsoft for its Windows operating system. Introduced with Windows Vista, WDDM provides a new architecture for the Windows graphics system, allowing for better performance, new features, and improved reliability compared to previous display driver models. WDDM enables features like fast user switching, improved 3D performance, and better support for multiple graphics adapters. tcc wddm better

• TCC: Common in server/HPC; can be simpler and stable for exclusive GPU compute use.
• WDDM: Better for mixed desktop/compute workloads and consumer systems.

Kernel Launch Times: In WDDM mode, every kernel launch must pass through the Windows OS scheduler, which can introduce significant latency. In TCC mode, these launches are much faster, which is critical for applications that execute thousands of small kernels per second. For NVIDIA GPU users on Windows, the choice
