Can you download the latest drivers from Nvidia and try installing them again? I wouldn't expect it to be a passthrough issue necessarily if they're showing up in Device Manager. Also, there are two other check boxes in the PCI device passthrough menu in the WebGUI. I dont know what the corresponding CLI arguments are though, but I would try enabling those if reinstalling the driver doesn't work.

I'm already reinstall the latest driver also seems not work , also in Nvidia control panel not showing 3d setting also .
