And that might be the reason why. I know from the past that some simmers stayed on FS9 because it considered 'the world' to be flat. In FSX however, 'te world' is a globe. And P3D takes it one step further to 3D. I have seen FS9 PC's suffocate after a switch to FSX and the same thing happened when moving over to P3D. With my proc sometimes running at 100% I know where the problem is.
