I noticed newer GeForce 7600 drivers are out for other sony laptops that have the same GPU (the new driver is 7.15.10.9812) and I was wondering why they haven't been posted on the site for the VGN-FE14Z despite being compatible?
I don't think it's a problem, if it's same GPU. However, read you read Sonys disclaimer and you will notice you do this at your own risk.
The Nvidia reference driver has been updates few days ago. I'm using the latest forceware release 158.18 on my desktop PC. And it is a real improvement in speed and quality compared to older Forceware releases for Windows Vista.
Lets hope SonyVAIO will update their drivers soon. 
Yeah, when you buy an entertainment system you like to think that they will keep up with the Nvidia updates!
