This is the official launch driver for GeForce GTX 680 the fastest, most efficient GPU ever built.

GeForce R300 drivers introduce several new industry-leading gaming features and will be released using versions 300.xx to 301.xx.

We have a discussion thread open on these drivers here.

New Feature Summary:

• NVIDIA GPU Boost Technology dynamically maximizes clock speeds based on workload of the game to push performance to new levels and bring out the best in every game. Learn more on GeForce.com.
• NVIDIA FXAA Technology shader-based anti-aliasing technology available from the NVIDIA Control Panel that enables ultra-fast anti-aliasing in hundreds of PC games. FXAA delivers similar quality to 4x multi-sample antialiasing (MSAA) but is up to 60% faster, enabling substantially higher performance in games. Note: This feature is disabled for games already have built-in support for FXAA. Visit GeForce.com to learn more.
• NVIDIA Adaptive Vertical Sync dynamically enables vertical sync based on your current frame rates for the smoothest gaming experience. Visit GeForce.com to learn more.
• NVIDIA Frame Rate Target dynamically adjusts frame rate to a user specified target. Support for this feature is enabled via third party applications via NVAPI. Visit GeForce.com to learn more.
• NVIDIA 3D Vision Surround Technology with a single GeForce GTX 680 you can expand your PC games across three displays in full stereoscopic 3D for the ultimate inside the game experience. NVIDIA Surround also supports triple screen gaming with non-3D Vision monitors. Visit GeForce.com to learn more.
  New Surround features:
  • Add in a fourth accessory display to get access to your email, web, or other applications while you game.
  • Maximize an application to a single physical display when in Surround mode (enabled by default).
  • Confine the Windows Taskbar to the center display (enabled by default).
  • Enable bezel peeking a feature which enables users to temporarily peak behind the monitor bezels using a hotkey (Ctrl + Alt + B). This feature is designed to be used in conjunction with bezel corrected resolutions.
  • Enables users to add or remove resolutions from the list of Surround resolutions (only those selected will be available to applications).
    Enables full center display acceleration for single wide display modes (center display must be connected to the master GPU).

NVIDIA NVENC Support adds support for the new hardware-based H.264 video encoder in GeForce GTX 680, providing up to 4x faster encoding performance while consuming less power.
