I have a neck injury that keeps me from properly looking over my own shoulder, and figured a quick solution would be to multiply rotational movement around the Y-axis, so that turning my head 15 degrees would effectively give me 30 degrees movement ingame. I realise moving away from a 1:1 ratio may cause nausea, but I am willing to deal with that, if the increase in rotation speed significantly improves on my seated gaming experience using the Rift.
Is there a config file that can be opened in notepad or something similar, so that this can be easily changed?
