One common thing I keep coming across when reading the 3D vision forums is the Win 10 1903 update, breaking support for the fix. If you don't mind being behind in Win updates, I'd defer all big Win updates for a while. I also have read on the MTBS forums, that a windows 10 update has already broken the activation's for Tridef 3D. I have a strong feeling that when 3D vision no longer works, it will be because of a Windows update.
Good news for now though, Nvidia 3D vision is coming to Steam VR via the Helix fix Aug 30
