No switches as far as I can tell on either steam or fs2 (checked via properties > ... both at the w10 level and fs2 level inside steam). Here's my tm.log ( says "failed to initialize ovr", which is the only thing I can see and vaguely understand. Just FYI, my oculus was up at the time and working fine!)
