Devices with multiple GPUs (such as PCs with an integrated GPU on the motherboard and an external graphics card) will be displayed here and labeled GPU 0, GPU 1, etc. If the internal graphics chip is using more resources than the graphics card, your graphics card is not being used. Ensure that the suitable device is being used by inspecting the connections between your Monitor and the graphics card.
