Nvidia offers nForce4 chipset driver downloads for NT-based Windows versions from 2000 up to and including Vista in the "Legacy" product type category on their download page. However, there is no official support for Windows 7 or newer, but Windows 7 has a built-in driver for the nForce 6 chipset, which is very similar.
To date, Nvidia has not released a complete chipset driver package for nForce3 and Windows Vista. However, Nvidia has posted individual 32 bit pre-release networking and audio drivers for Windows Vista Beta 1 that support the nForce3 series (and 64 bit). It is also possible that nForce4 chipsets may experience similar problems with the RAID and ...
Due to the high resolution (2560×1600), the 30-inch model requires a graphics card that supports dual-link DVI. When the monitor was released, no Macintosh models were sold with a dual-link DVI port. A Power Mac G5 with the new Nvidia GeForce 6800 Ultra DDL graphics card was initially required to run the display at full resolution. [6]
In the R300 drivers, released alongside the GTX 680, Nvidia introduced a new feature called Adaptive VSync. This feature is intended to combat the limitation of v-sync that, when the framerate drops below 60 FPS, there is stuttering as the v-sync rate is reduced to 30 FPS, then down to further factors of 60 if needed. However, when the ...
