For the CG, it may also depend on what type of aircraft you want to fly with and where and if you play in 4K or 1440P.
I have an ‘‘old’’ RTX 2070S Gaming OC 8gb I use only the TBM930 and the Cessna 172, the other models do not interest me, I have a mix of Ultra and High in 1440P and it is impeccable, but if I had to use airliner on large airport, I will have problems
Of course if you can buy a 3080/90 for example it will be perfect, but we also see people with big Gamer configuration who have problems while others don’t with a PC that is less performing.
That’s the magic of the Flight Simulator series, overpowered or entry level PCs, we all have the same problems
