Well to be honest, everyone has different point of taste. For me balance between requirements and results is not so good - moreover people have plenty of cores in own machines and they are rarely used at all. It is not CPU fault, it is programmers one.
So this is the chance. Newer engine, newer solutions. Better they use it, because they will not make new Edge in minimum 5 years and we will be stuck what it is going to be given.
A lot of PC power goes to unknown. Graphic effects are not hollywood ones, terrain shape and complexity is quite poor. Only 3D models are great and un-see things like physics.
One's said to me "DCS is great sim, but only for single player". I can't say he is wrong.
