Hehehe, it seems you don't really like NVIDIA, Umberto.
Really don't know why you deducted this, since I've said exactly the opposite, that your card should perform faster because it's better than mine, I always had nVidia, and I believe they are better for FSX but, having a Mac, I don't have much choice than using an ATI.
you haven't noticed my active fps limiter locked @30fps due to smoothness.
That doesn't really make any difference because, in that specific moment your fps was at 27.8 (in the first screen), to be effectively working as a limiter for smoothness, you should have been in a situation of of a frame rate *always* higher than 30, being brought back to 30 just because of the limiter. In your situation, you would probably get even better smoothness by limiting at 20.
we all know, fsx is cpu limited not gpu limited, and i am using an old Core2Duo, not a quad. (xeon) It doesn't make sence, to compare graphiccards concerning FSX on totally different designed hardware. A stronger gpu doesn't raise fps in FSX extremely, it allowes you to use more quality settings without fps impact.
Of course, I didn't know what CPU you used. In fact, just because FSX is CPU limited, I assumed that, with such good card, you would be using a far better CPU. So yes, perhaps your lower frame rate it's due to your CPU only.
all my screens are made in High Definition
My monitor here it's 4:3, so I can't go higher than 1600x1200 but, I have exactly the same frame rate in Windowed mode as Full Screen mode, no noticeable difference, not at Zurich at least.
and with active filtering options (nvidia inspector) ATI doesn't offer and the 4870 couldn't handle without swapping due to limited gpu memory.
That's simply confirm my point: if my card, with less than half VRAM CAN show the scenery properly, it's not a problem of the scenery (for example, if that objects would allocate too much VRAM due to a bug or so), but more likely a video driver bug or just a tweak.
As every Screenshot is around 8mb, i have reduced visual quality extremely, so this isn't the normal approach of a nvidia card.
The quality of the screenshot itself doesn't have much to do with this problem, nor I made any remark about it.
You should give Nvidia a chance, sometime.
Again, I've said clearly your card is better than mine, and I would rather be able to use an nVidia myself BUT, this doesn't have anything to do with the fact that a video driver bug is always possible, or that a tweak in FSX or a tweak in the video driver settings might cause such kind of visual problems, without being the scenery's fault.
If it is possible i would like to know which of the Switzerland Pro X files have to be turned on or off, to get the status i am used to without flickering, manually?
The Autogen exclusion bug wasn't specific in any way to Switzerland Pro, it happened just the same even with the default scenery and yes, to reintroduce it, we would need to change our files.
If more people would eventually report this issue as a problem, compared to how many used to report the autogen exclusion problem (everybody has HIS own opinion about what is most disturbing visually), we might consider going back as it was, but as it stands now, I consider that unnoticeable flickering a way less of the two evils compared to the autogen loss.
PS: maybe, the pole thing will be gone with my coming up new FSX installation, new hardware is on the way, which will not be a mac.
That would be a good choice, if I was a gamer, I probably wouldn't buy a Mac too BUT, there's nothing better than a Mac Pro, for a developer, because it's far more stable than any PC I had (and I had many of them), and the Xeon is THE best CPU for graphic development and rendering. It's an 8 cores, BTW, even if FSX doesn't make much use of it...
