I found the problem: It was installed in my system the ASUS Enhanced Display Driver. I don't remember actually install it: It should have been installed already when I took the brand new "box". I uninstalled it and never look back. I suspect that is a bugger for directX applications too, I 'll post an update.
I want to thank all people in AAA & SAS forums, as well as two friends outside forums, for their invaluable help. By listening all these days the "it might be this one or the other" I got gradually sure of what it was NOT. I have now all the time to optimize my system (the GTX 260 settings are fairly low now) BUT I should say that there is now a very noticable difference, the IL-2 is running ultra-ultra-smooth with highest settings. (a dream to fly a high alt mission with "perfect" landscape at last.)
