Microsoft is working on an update to Windows 10, which among several other things, adds a GPU utilization tab to Task Manager. You will be able to monitor each individual GPU in your machine, and Task Manager will give you live utilization stats for the GPU's 3D load, Video hardware-acceleration (encode/decode) load, dedicated memory usage, shared memory usage, and basic driver information such as driver version and date. For now the update is part of Windows 10 Insider Preview Build 16226; and will make it to the main-release in the coming months.
