Why Windows 8.1 Delivers

The free update from Windows 8 to Windows 8.1, just released today by Microsoft, packs a host of enhancements — from better graphics to the addition of Outlook to Windows RT.

The update carries plenty of benefits for GeForce users because it includes the latest version of the Direct3D API, called DirectX 11.2. We were the first GPU manufacturer to release WHQL-certified graphics drivers for Windows 8.1, and we’ve continued our close collaboration with Microsoft to implement new features in DX 11.2, including:

  • Support for higher resolutions with DPI scaling
  • HLSL shader linking — Windows apps can now compile shaders offline, and then link them together at runtime to improve performance versus real-time compilation
  • Tiled resources — Load only the required resources, resulting in very high-resolution imagery with minimal use of GPU memory.

Our GPUs based on Kepler architecture are ready for DX 11.2 and will immediately support these features.

GeForce users also get access to our high-quality drivers, which deliver the best possible gaming experience. This effort requires hundreds of engineer-years and thousands of hours of testing and certification, but it’s essential to ensure optimal performance and stability for the world’s largest gaming platform.

In addition to gaining Outlook 2013 RT, Windows RT 8.1 users will enjoy a variety of new features. Among them are workplace join and third-party mobile device management, tools that will ensure that Windows RT devices fit more easily into enterprise settings.

Our Tegra processors already bring ample power and speed to Windows RT devices. With Windows RT 8.1, the experience only gets better.

You can download Windows 8.1 through the Windows Store now.

    DPI scaling requires special software support from older apps? Is it possible to do selective (per-app) DPI scaling in applications written for older Windows ?

    hey, lots of people are complaining that after upgrading to w8.1 they can only use intel hd, the driver for nvidia does not work at all, can you please fix this as soon as possible

  • Filipe Antunes

    Why can’t I use NVIDIA now that I upgraded my windows to windos 8.1 ?!

    i have gtx 660 and installed windows 8.1 two days ago.checked directx version which is still 11.when 11.2 will be available for download?

  • Eddie

    I don’t understand, I have a Kepler based geforce but it’s like I run the same games I use to play but I didn’t notice no performance increase from DX 11.2 at all. Bellow I’ll describe my hardware.

    Windows 8.1 Enterprise.
    Geforce gt 650m GDDR5 1GB.
    And lastly my driver version is the 331.40 beta.
    I also tried the previous version which is a WHQL, the 327.23.

    Any ideas of what would be the problem ?

    Thank-you.

    how to fix please help. when i download the driver from nvidias site it says hardware not detected n i have a 2 gb dedicated graphic in the computer

  • steve

    Why couldn’t MS have told people of problems with nvidia before they updated to windows 8.1. So many people must be affected and yet not a word. I would have delayed. It is completely unacceptable.

  • http://Geforce.com/ Manuel Guzman

    Do you have a notebook or desktop GPU? If notebook, please tell me which notebook make and model. I will also need your graphics card device ID. To look up your graphics card device ID, click on the Windows key and the letter “R” on your keyboard at the same time to bring up the “Run” window. In the “Open” field, type “msinfo32″ and then press OK. Under the Components section, choose Display. Please provide me with the PNP Device ID as shown in the screenshot below. I need the numbers which follow it.

    After upgrade to Windows 8.1 all software is using Intel HD graphics 4000 instead of NVIDIA GeForce GT 650M. Both devices show up in Device manager as properly installed and I can find no way of forcing windows to use the NVidia instead of built in Intel graphics. I have checked Windows display settings, Photoshop, Second Life, Blender, Maya and a few others and all show Intel.

    Morons, before boasting make sure your drivers actually work with Windows 8.1. Just upgraded my Dell XPS 15 to Win 8.1 and now I get a stupid “Prototype Test Only” on my screen. I have to now waste hour of my time trying to find an updated driver to make it go away.

  • Rogério Barbosa

    My Toshiba L50-A-103 has two graphics cards, an Intel (R) HD Graphics 4000 and Nvidia GeForce GT 740M.

    In my workplace I use a external SyncMaster 2032BW monitor with a resolution of 1680 x 1080.

    I upgraded to Windows 8.1 and I can no longer use the nvidia card as default.

    Now only detects the Intel with maximum 1366 x 768.

    Is there a solution to this problem?

  • Ron Straining

    Yeah – update – NOW MY CARD Is Not RECOGNIZED – called tech support, told to reinstall windows 8 – THANX A LOT

  • Jackie KW Tong

    I just found the solution to my setup with this same symptom of “hardware not detected”. The key lies in BIOS which had specified “Switchable” for 2 graphics card: a. the Intel build in graphic chip set and b. the Nvidia GT330M of my notebook – somehow the Intel chip set always dominates and “hiding” the nvidia graphic card. Below was what I did – not sure if this works for other computer / notebook config as well but a simple process so anyone who has been desperate for the solution could give it a try :
    – when switch off computer from Windows 8.1, choose “Shut Down” while pressing the “shift” key – somehow this is the real shut down (or otherwise cannot bring up the BIOS)
    – Switch on the computer and before Windows starts get to the BIOS; for ACER it is after switch on to get into BIOS (check your computer manual)
    – Under setup on Graphics Card option, change from “Switchable” to “Discreet” ; save the BIOS setting and quit to start up Windows 8.1
    – Install the latest NVIDIA 331.82 driver – hardware should now be detectable and installation should perform , as expected.
    Good luck !

    VIDEO TDR FAILURE, every time. I’ve tried so many drivers. Every time the GPU tries to run a game, after a few minutes I get the BSOD, then the VIDEO TDR FAILURE error, citing nvlddmkm.sys. This also happened with Windows 8, before the 8.1 upgrade. I’ve tried everything and can’t find anybody who has found a solution online. The tech support guys whose job it is to tell me to reformat my OS to fix any problem I have told me to reformat my OS. Go figure. (MSi GT60, GeForce GTX 675M). Please get this driver/Windows 8/8.1 stuff figured out.

    Oh, yeah, and direct x diagnostics don’t recognize the Nvidia card, just the Intel. Never did, even before the 8.1 upgrade.

    I was having the same problem with my computer yesterday after updating to Windows 8.1 but my graphic’s back alive and healthy now. What i did was i advanced restart my computer and get into bios and set to default to all setting in bios and restart your computer and update your graphic driver to the latest. That fixed my graphic problem with windows 8.1. Hope u guys can fix yours as well …..

    Indeed. However a number of Nvidia drivers including the latest, 332.21, simply will not install on my rig which has an Nvidia 670 card. I’ve reported it as an issue but have received no answer. Currently running with 326.6 but with no 3D support.

    After being advised by MS support, I had to go back to the original windows 8 because my dual nvidia gt650m driver updates would not work. Only one would work when I updated the drivers and both would work for a while each time I rolled back to an earlier driver version. (presumably the version I had before the 8.1 upgrade) It was a headache as I had a problem with my backup files after I did a system restore to remove 8.1. Anyways, it works now on 8.0 but it is tough not to upgrade again as they tell me how much ill benefit at every turn. Seems like there is an ad everywhere. An update on when its safe would be nice.
