### Windows version
Windows 10 Pro 1709 works for me, but 1803 does not (may be the UEFI). [I have heard that the 1803 version comes with a Spectre patch and the performance is bad.](https://www.reddit.com/r/VFIO/comments/97unx4/passmark_lousy_2d_graphics_performance_on_windows/). The Spectre patch can be disabled.
