Windows misreporting high GPU usage #251

Task manager seems to misreport the GPU usage of a GPUI app using the blade Vulkan backend at 80-100% GPU 3D usage.

This occurs on my machine when using the default Nvidia 3D setting Vulkan/OpenGl present method set to Auto.

If I set the Nvidia 3D setting Vulkan/OpenGl present method to Prefer layered on DXGI Swapchain. It results with the GPUI application being reported at just 3% GPU 3D usage in Task manager. This seems much more reasonable.

I am not sure why a DirectX swapchain would make Task manager correctly report the GPU usage.
