As far as i can tell there is no way to quickly toggle between VR and non-VR mode (if i am wrong please let me know
But i was thinking that perhaps the settings such as which screen to use, what resolution, and whether to use VR mode was something that is stored in a settings file somewhere? If so could someone point me to it, because then ill simply have separate copies of that. I do play almost 100% in VR, but some trade route planning etc is better without the Rift.
