NVIDIA has already released drivers for its GeForce-based PC graphics cards that support Windows 8. However, those drivers could not be used on PC with any other version of Windows. Today, NVIDIA launched new GeForce 304.79 beta drivers that finally add Windows 8 support in additon to support for Windows XP, Windows Vista and Windows 7.
In a post on NVIDIA's blog, the company also announced these are the first GeForce drivers that support TXAA antialiasing. This new antialiasing method currently works only on graphics cards that have NVIDIA's GeForce GTX 600 Series GPUs. NVIDIA says:
... this anti-aliasing technique not only reduces the level of aliased stepping on edges and lines far beyond that of MSAA, but also reduces temporal aliasing to a significant degree. More commonly known as shimmering, temporal aliasing is typically seen on chain-link fences and other surfaces when the player’s camera moves, and with this addition TXAA approaches the level of fidelity seen to date only in big-budget CG movies.
Unfortunately, no PC games currently support TXAA antialiasing. That should change soon; an upcoming software update for the just launched MMO The Secret World should allow for owners of the game and the supported graphics card to experience the new feature.
