A common "pro" setup involves leaving your primary GeForce card in (to run Windows and games) and setting a secondary Professional card to TCC for dedicated background rendering or AI processing. How to Switch Modes
TCC is NVIDIA's specialized driver mode designed for compute cluster nodes. It transforms your GPU into a dedicated computational powerhouse by disabling all graphics functionality. In TCC mode, the GPU is completely devoted to computing tasks without any display obligations. tcc wddm better
For workloads with many small kernel launches, these spikes can kill performance. One developer testing a kernel-heavy algorithm on an RTX 3090 found that switching from WDDM to TCC boosted throughput from — a 60% improvement . A common "pro" setup involves leaving your primary
