Best conf settings for GeForce GTX550Ti ?

[Phabius]

I've been dealing with the conf file, trying to dial the best settings for my nvidia GeForce GTX550Ti.

Still, I have some issues like FMB positioned trees with no shadows (shadows=2), and some nasty rendering of airfields and objects in the distance (yes, the two last lines are already added to the conf file), with moving parallel lines...

Windows XP SP3
i7 960
4GB RAM

Any suggenstions for the conf file settings for max visual experience?

Thanks!
