If your complaint is a lack of up or downdrafts in or near clouds then the CFD model does matter. It matters because thats what Asobo is currently working on and to experience what is being worked on, it needs to be enabled in the flight model.
If your complaint is a lack of turbulence then I can’t tell you if there is turbulence or not. How are these things modelled? The pilot perspective is moved about inside a model that moves about in a simulated environment. It is the relative movements of the pilots perspective and the two other environments (plane and outside world) that would provide the illusion of what I would call turbulence.
Maybe its there but it isnt modelled? maybe its modelled but not to your satisfaction? Who knows.
But we really shouldn’t conflate winds with turbulence as they are not exactly the same thing. One is a general flow and the other is chaos caused by resistance to a myriad of air movements (as I see it). But the updrafts and downdrafts do exist and if you can’t find them then you should try the default C172 for a few weeks.
