Same issue with kernel 4.10 - 4.12 here.
CPU - AMD Ryzen 7 1700
MB - Asus Prime x370 Pro
Host GPU - NVidia GTX 750ti
VFIO GPU - AMD Radeon RX480
Host OS - Manjaro 17.2
Guest OS - Windows 10
With npt=1, everything is fast, except GPU fps is 10-15 in Skyrim
with npt=0, everything is slow, GPU fps is ~30 in Skyrim
