Just released today, the official nVidia driver for Solaris 10 X86. On the nVidia driver page you’ll need to look under “Quadro” to find the driver, but don’t let that scare you off, this driver will support Quadro as well as the full line of Geforce cards. Word has it that even PCIe cards are supported. You can find more information in Alan Hargreaves’ blog. A support forum is already avalible at NVnews.net.
