I do understand the concept and it isn't a bad premise to work from since FSX is so CPU intensive.

The developer, while simultaneously trying to protect his proprietary information and marketing the product, has given several very specific hints as to how the program works. You may be that one user who understands the concept, but most folks that are trying the demo are not even reading what the developer has said about the product. The software in no way modifies or even references fsx.cfg. I have confirmed this. The factors that it changes dynamically can however be influenced by the initial settings of FSX startup which is determined by the fsx.cfg. The software does not appear to use a wide range of tweaks, only a few.
Perhaps, those trying the demo are only seeing the promises and not, again, the very specific hints as to how the software does what it does. Also the developer gives no good guidelines (but I repeat, several good hints) about how to set the FPS sliders in the application.
I would have predicted that your higher end system would benefit less from FA. And, would have made some suggestions for the FPS sliders based on whatever your current performance might be. Based on my reading of the developer's words (and ignoring his marketing), my testing, and what others, like you, have posted about no improvements, there are also certain configurations, such as photoscenery that I would predict benefit very little from FA.
Perhaps the devs are "over-marketing" or perhaps they are using their support system to help tune customers FA config. These factors have not been subject to my research or testing.
