Despite the performance gains of TCC, WDDM is necessary in specific scenarios: [Multiple GPUs / Processes] CUDA Memory De/Allocation Slow

Under , the GPU is a shared resource managed by the Windows OS. The GPU Scheduling engine decides which process gets access to the GPU and when. While this is excellent for multitasking (running a game while browsing the web), it introduces latency. Every time a compute kernel is launched, the OS must context-switch, save the state of the GPU, and manage memory. This creates "jitter"—unpredictable delays that kill performance in time-sensitive applications. tcc wddm better
