Just an information piece really. I've been using Nvidia's 388.00 drivers to date, 388.13 & 388.31 have given me really bad head tracking stutter inside the Rift. So much so that it makes it totally unplayable without making me feel sick.
Just hoping anyone with the same problem will come across the title of this post as it might help them out if they've updated drivers and not thought to roll back.
Also it's worth deleting the temporary driver folder C:\NVIDIA\DisplayDriver\... (driver version) as Windows 10 keeps taking it upon itself to reinstall the bad driver again on mine if I leave the new extracted driver in that temp install folder.
