Nvidia has published a new beta graphics driver to accompany the arrival of its GeForce GTX 560, allowing you to take advantage of enhancements and fixes ahead of WHQL certification. Although the company mentions performance improvements for both GeForce GTX 400 and 500 series cards, it only cites specific gains for the GTX 560 and 580. The figures below were obtained by comparing today's v275.27 beta release against last month's v270.61 WHQL drivers.
|Application||GTX 560||GTX 580|
|Batman: Arkham Asylum with PhysX High||14%||15%|
|Bulletstorm with Antialiasing enabled||15%||13%|
|Civilization V with SLIed GPUs||--||5%|
The release notes also mention a 12% increase in gaming performance for dual-core processors during certain CPU-limited situations. Game-related single-GPU bug fixes include issues that caused blurriness in Resident Evil 5, as well as flickering in Empire: Total War and Battlefield: Bad Company 2. Meanwhile, Nvidia has resolved glitches in Homefront, World in Conflict: Soviet Assault, Lost Planet: Extreme Condition, and Crysis when running them SLIed GPUs.
The 275 family represents a siginficant update over the present 270 drivers with features such as silent automatic SLI, multi-GPU and antialiasing profile updates. This is in addition to the optional "Nvidia Update" feature in the 270 line, which notifies you about new driver releases. There are also various desktop scaling and 3D Vision features, including a new interface for the former and more profiles for the latter. You'll find more details on our download pages above.
