I have upgraded to 1.4 and ever since I have had a problem with VR - The VR randomly shows the backwards view and can't be turned around unless you turn your head right around. This is very annoying in the middle of a race to suddenly only be able to see behind you.
My guess is that some input device that you have is triggering what you've mapped to "Look Back". Most likely the same problem will happen when running Automobilista 2 when not in VR?
OK, the next question is what VR headset you are using? Maybe it has something with to do with the headset losing tracking or problems with SteamVR recentering.
lol I fixed the problem by cleaning the infrared cameras to help with the tracking and also replacing the batteries in the controllers. Seems to have done the trick.
