Hi there,
running 11.50b2 and had two times CTD when creating a flight with the TBM; starting with default C172 and then changing to TBM works so far - I didn't find anything in the log; I will try to re-create this and send you the log.
One little thing with 11.50: the throttle lever overlay is flickering/flashing (as long as it is visible, it doesn't pop-up randomly or something similiar).
PS: in general, FPS with the TBM under vulkan is "not impressive" compared to other a/c - but I guess some people stated this already.
