GeForce4 Go
This family is a derivative of the GeForce4 MX family, produced for the laptop market. The GeForce4 Go family, performance wise, can be considered comparable to the MX line. However, support wise, some users have become rather irritated at an uncharacteristic lack of driver support from NVIDIA. Instead of supporting this family of chips, NVIDIA redirects users to the manufacturer's webpage. At least in the case of Sony's support for the PCG-NVR23 Vaio laptop, the drivers provided are exceedingly out of date.
One possible solution to the lack of driver support for the Go family is the third party Omega Drivers. However, it is not recommended that one install these drivers unless one is willing to accept the risks. Using third party drivers can, among other things, invalidate warranties. The Omega Drivers are supported by neither laptop manufacturers, laptop ODMs, nor by NVIDIA. NVIDIA has also recently attempted legal action against Omega Drivers.
NVIDIA?s own solution to the problem is to try drivers from
www.laptopvideo2go.com. This website hosts desktop display drivers which have been modified to install on a notebook. The drivers found on this website do not contain any laptop specific modifications and thus may or may not be better than drivers provided by your laptop's manufacturer.
