Enable TCC on your compute GPU (e.g., GPU 0):
You can run a single kernel for weeks without interruption. Furthermore, TCC allows for "Peer-to-Peer" (P2P) transfers between GPUs (NVLink) without copying memory through system RAM. WDDM often blocks direct P2P for stability reasons. 3. Remote Desktop (RDP) Support This is the "killer feature" for data scientists. With a WDDM GPU connected to a headless server (no monitor), Windows Remote Desktop will not render CUDA properly. You usually get errors like "CUDA driver version insufficient for runtime version." tcc wddm better

Stop crippling your expensive GPUs with WDDM overhead. Switch to TCC. Your training epochs will thank you. Updated for NVIDIA Driver R555+ and Windows 11 23H2.
