That didn't work ? and my light fx wont save after restart?
Didnt have this problem with vista.
Sorry it didn't work; I don't know what to tell you. The Vista drivers should work fine with Windows 7.
Your light FX problem is a long-standing issue with the XPS630i. Others on this board have suggested trying different versions of the nvidia system tools and ESA software. Most seem to rely on 6.03. In my case, 6.05 worked the best for months--then I did a reinstall of Windows and I now have the same problem as you do. I guess you'll just have to experiment a little.
