Random tech support contribution for the week: =)
Been testing Nvidia drivers a lot lately (a new one out almost every week) and thought I'd see if the latest round has made any difference to WoW.
Trotted my lowbie Monk out to my favourite testing spot in Elwynn Forest, and noticed some jerkiness while panning around with the mouse. Hadn't noticed that before, but hardly played BfA, so could have easily missed something what with the changes to Windows 10, BfA and FS Exclusive Mode removal.
Was almost going to blame the latest driver, then noticed it wasn't happening if I panned using the arrow keys; only the mouse. Anyway, looks like a bug fix in 2017, combined with the removal of the hardware cursor more recently have caused the problem.
Adding this line to the Config.wtf file completely solved the problem for me, and back to buttery smoothness.
SET rawMouseEnable "1"
