I DisplayLink and have the card in the only 1x slot I have (ASUS ROG B350-F Gaming), I was so happy because it appeared to be working but alas, after about 1 hour the computer froze (no bluescreen appear it just froze).
Last even errors:
The Oculus VR Library Service service terminated with the following service-specific error:
The access code is invalid.
which does seem like a common occurence because a lot of similiar events:
OVRServiceLauncher could not be found.
Anyone with better luck with ASUS ROG B350-F Gaming
