If you're a front-facing player on Oculus, and you'd like smooth turning in Left-Hand Path, I've just added that in an experimental build.
To try it out, right-click on Left-Hand Path in your Steam Library, go to "Properties", and then go to "Betas". In there, choose "smoothturnalpha".
Once you've got that beta (which also features a few other improvements and fixes, including the Teller Of Tales achievement now working for Nehemoth), you can enable Smooth Turning by going to the menu, then ticking the "Smooth Turning" checkbox.
Let me know what you think, and if it works for you!
