Nuovi Driver nvidia per Windows 257.21 whql e Linux 256.35 Certified


257.21 WHQL

This is the first driver release from the Release 256 family of drivers (versions 256.xx to 259.xx). This driver package supports GeForce 6, 7, 8, 9, 100, 200, 300, and 400-series desktop GPUs as well as ION desktop GPUs. Learn more about Release 256 drivers here .

New in Version 257.21

  • Adds support for Blu-ray 3D with NVIDIA 3D Vision technology. Learn more about the hardware and software requirements here .
  • Increases performance for GeForce GTX 400 Series GPUs in several PC games. The following are examples of some of the most significant improvements measured with GeForce GTX 480. Results will vary depending on your GPU and system configuration:

Upgrades PhysX System Software to version 9.10.0223.

  • Adds support for OpenGL 4.0 for GeForce GTX 400 Series GPUs.
  • Adds support for CUDA Toolkit 3.1 which includes significant performance increases for double precision math operations. See CUDA Zone for more details.
  • Adds support for new extreme Antialiasing modes for 3-way SLI PCs, including up to SLI48x AA for GeForce 200 series GPUs and up to SLI96x AA for GeForce GTX 400 series GPUs.
  • Adds support for a new ‘Quality’ mode for NVIDIA’s Ambient Occlusion control panel feature.
  • Adds a new NVIDIA Control Panel setup page for SLI and PhysX for ultimate control over multi-gpu configurations.
  • Adds a new NVIDIA Control Panel feature for ultimate control over CUDA GPUs, allowing the user to effectively choose which GPU will power each CUDA application.
  • 3D Vision customers can download the v257.21 3D Vision drivers here.
  • Includes numerous bug fixes. Refer to the release notes on the documentation tab for information about the key bug fixes in this release.
  • Additional Information:

    • Installs HD Audio driver version (for supported GPUs).
    • Supports the new GPU-accelerated features in Adobe CS5.
    • Supports GPU-acceleration for smoother online HD videos with Adobe Flash 10.1. Learn more here.
    • Supports the new version of MotionDSP's video enhancement software, vReveal, which adds support for HD output. NVIDIA customers can download a free version of vReveal that supports up to SD output here.
    • Supports DirectCompute with Windows 7 and GeForce 8-series and later GPUs.
    • Supports OpenCL 1.0 (Open Computing Language) for all GeForce 8-series and later GPUs.
    • Supports OpenGL 3.3 for GeForce 8-series and later GPUs.
    • Supports single GPU and NVIDIA SLI technology on DirectX 9, DirectX 10, DirectX 11, and OpenGL, including 3-way SLI, Quad SLI, and SLI support on SLI-certified Intel X58-based motherboards.
    • Supports GPU overclocking and temperature monitoring by installing NVIDIA System Tools software.


256.35 Certified


  • Fixed a regression in 256.29 where Performance Level clock frequencies were reported incorrectly in nvidia-settings.
  • Fixed a 3D Vision Stereo bug that caused the stereo glasses to not toggle when the flat panel was not running at its native mode timings.
  • Fixed a bug that caused nvidia-settings to crash when rendering its thermal gauge widget if the range of valid values for the thermal sensor was empty.
  • Fixed a bug which prevented use of high performance PowerMizer levels on systems with certain ACPI configurations.
  • Fixed a bug that caused non-primary Fermi GPUs to fail to initialize framebuffer memory. This caused a variety of symptoms, up to and including system hangs.
  • Added unofficial GLX protocol support (i.e., for GLX indirect rendering) for the following OpenGL extensions:
  • Improved Thermal Settings reporting in nvidia-settings to accurately reflect hardware configurations with multiple thermal sensors.
  • Fixed an interaction problem between Compiz and 'screen-scraping' VNC servers like x11vnc and vino that caused the screen to stop updating. Fixes Launchpad bug #353126.
  • Enhanced VDPAU to add basic support for Xinerama. VDPAU will now operate on a single physical X screen under Xinerama. See the README for more details.
  • Enhanced VDPAU's handling of corrupt clips of all formats on GPUs with VDPAU feature set C to be at least as good as on GPUs with VDPAU feature set B. This significantly improves various clips provided by user eamiller.
  • Fixed a bug in Xv attribute handling that caused hue, saturation,brightness, and contrast values to be misapplied when using an Xv overlay adaptor.
  • Fixed a bug in the XvMC driver that prevented it from working on systems with AGP graphics cards.
  • Enhanced VDPAU to clear all VdpVideoSurfaces to black when allocated.This provides more consistent results when using a surface as a reference when no prior decode operation has written to that surface.In turn, this improves the results of decoding some corrupt streams,such as "p_only_no_play" from ffmpeg bug 1124.
  • Implemented new APIs to allow sharing VDPAU surfaces with OpenGL andCUDA. The OpenGL extension is GL_NV_vdpau_interop. For CUDA, please
    see the documentation in the CUDA toolkit for details.
  • Worked around a bug where the combination of a GPU with VDPAU feature set A together with specific motherboard chipsets could cause visible corruption when decoding some MPEG-2 streams
  • Fixed a bug that prevented the VDPAU overlay-based presentation queue from being used more than a few hundred times per X server invocation.
  • Renamed the driver file to, as a small step towards reducing the filename collisions between NVIDIA's and MESA's OpenGL implementations.This driver file is used by NVIDIA's and, and should never be used directly by applications.
  • Changed the SONAME of,, and to be ".so.VERSION", rather than ".so.1".These driver files are only used by other NVIDIA driver components, and are only intended to be usedby components of the matching NVIDIA driver version.
  • Removed the "-pkg#" suffix from the NVIDIA Linux .run files.The packages are now simply named "".On Linux-x86_64, a package which omits the 32-bit compatibility libraries is also available: ""
  • Simplified the directory structure of the Linux extracted package; most driver files are now just contained within the top level directory of the package.Pass the '--list' option to the .run file for details.
  • Removed precompiled kernel interfaces from the NVIDIA Linux-x86 .run file; these were ancient and had not been updated in years.Going forward, NVIDIA does not plan to provide precompiled kernel interfaces with the Linux .run files.However, nvidia-installer and the .run file will retain the ability for users to add their own precompiled kernel interfaces via the '--add-this-kernel' .run file option.
  • Compressed the nvidia-settings, nvidia-installer, and nvidia-xconfig tarballs with bzip2, rather than gzip.
