Low-end system settings please?

Can someone please post what settings should I change to get a decent gameplay on a system as such:
P4 2.6
GeForce FX 5900
512 RAM
I know it's very low but it's all I have now and I want to play the game very much doesn't matter what graphics((
If it's possible can someone attach an .ini file. Very appreciated!

It may be possible for you to play if you get atleast another 512 or better 1gb of ram, Gothic 3 eats ram for breakfast, 1gb is the bare minimum to play,its impossible to play with just 512 mb of ram, the rest of your sys should be enough if you play on low and shader 1.1.

You will not get a decent frame rate on such a system. 512 MB RAM is not enough. Just set everything to the lowest setting. Maybe it runs
