You can switch modes using the NVIDIA System Management Interface ( nvidia-smi ) tool via command prompt (requires admin rights): To set to TCC: nvidia-smi -g -fdm 1 To set to WDDM: nvidia-smi -g -fdm 0
WDDM pages GPU memory in and out of system RAM, treating GPU VRAM like virtual memory. This leads to unpredictable performance spikes and memory fragmentation. For large datasets that should remain on the GPU (neural network weights, particle buffers), paging is disastrous.
WDDM's modern architecture ensures that graphics drivers are well-suited to handle the demands of contemporary graphics APIs and applications. When combined with TCC, it provides a robust foundation for delivering high-quality graphics experiences. tcc wddm better

Under WDDM, every time a software program sends a command (kernel) to the GPU, it must pass through the Windows operating system layer. This introduces a small amount of latency (overhead) measured in milliseconds.TCC allows applications to communicate directly with the NVIDIA driver hardware abstraction layer. For workflows that launch thousands of tiny parallel jobs successively, , resulting in faster total execution times. Maximizing VRAM Utilization You can switch modes using the NVIDIA System
(If you see "WDDM" – you are in slow mode)
By leveraging the Tiled Copy Engine, TCC WDDM optimizes the way graphics data is processed and moved within the GPU. This results in reduced overhead and improved performance, especially in graphics-intensive applications. WDDM's modern architecture ensures that graphics drivers are
