Seems ironic that there is comparisons of FSX running now like a well oiled machine 7+ years after its release, all the while weve been whining about FSX performance and the tweaking masters degree needed, with all its addons to perk it up, and then its compared to p3dv2 with default scenery, and default everything else.
Think open minded. Here is P3dV2 which looks pretty good already at default, with a overhauled underlying engine, with alot of "modernization" to it under the hood, and after all that there is doubts and complaining still. Now think of the possibilities that devs can do to take advantage of all that. And since we have modern hardware, DX11, (which means Nvidia driver updates actually mean something) and a core developer who is more than willing to cooperate with customers and its addon developers, prepar3d v2 will not take long to work out all the teething issues. Not even close to 7 years. And a year ago the flight simming prognosis for the future was kinda grim.
Ive just got the developer option for now until I can afford the pro license but I have to say its pretty smooth. Who cares about the FPS. Its smooth! Just be reasonable with your expectations, and sliders. Push your system too hard right away, and of course your going to curse at it. Be patient.
Is it perfect? Of course not!! to expect it to be is ridiculous. The bugs and teething have to be worked out. But this will be a fantastic next year in what we will be able to accomplish.
