Simultaneously with its new GeForce GTX 295 graphics card, Nvidia has released a batch of updated ForceWare drivers that bring both support for the new product and bug fixes. The ForceWare 181.20 release is available right now for Windows Vista x86, Windows Vista x64, Windows XP x86, and Windows XP x64.
The drivers also add support for the GeForce GTX 285—a new top-of-the-line single-GPU card based on the same 55nm GT200 "B" chip as the GTX 295. Aside from that, Nvidia has made some bug fixes pertaining to Age of Empires, Company of Heroes, Grand Theft Auto IV, Prince of Persia 4, Serious Sam 2, S.T.A.L.K.E.R., and World of Warcraft: Wrath of Lich King, alongside other, non-game apps. Oh, and the new drivers apparently tweak power management for GeForce GTX 260 and 280 cards, too.
You can peruse detailed release notes for the ForceWare 181.20 drivers right here in PDF format. This release includes fixes from the 180.84 beta release, if I'm not mistaken, since that never received WHQL certification.
