As others I invested heavily in Xplane 11 and eventually bought Xplane 12.
Whilst I enjoy flying airliners in 12 the lack of scenery for vfr flights and the fact that my favourite TBM 900 remains some way away from xp12 means I now use both.
GA flights including hot start CL650 I run on xp11 and run commercial jets like TollissA321 on xp12 as well as CL650.
If orbx and plane developers don’t catch up and xp11 does not get supported then my hobby will die with xp11
Shame as xp12 has some great plus points Water on the runway and better clouds is not enough.
