Welcome to H4ck 3D,

Your source for NVIDIA® 3D Stereo & ForceWare related Tweaks!

NVTray provides some extra quality tweaks that both the default NVIDIA tray icon and control panel are lacking. I especially wanted to be able to select more Antialiasing modes, as well as OpenGL and Direct3D options right from the tray icon. Also, the utility is able to run automatically at startup thus making it a bit easier to change my settings before playing a game or running a benchmark. This program requires .NET Framework 2.0 to support a broader range of systems.


*appearance may vary, depending on WindowsXP themes

NVTweak unlocks many extra options in the Classic NVIDIA control panel/driver, including but not limited to - Overclocking, AGP & Hardware settings, Fan control, Temperature settings, Debugging, Twin View, Video Mixing Renderer, OpenGL 2.0 support, 3D viewer types (for 3D Stereo drivers), and more!  Below is a quick sneak peek of some of the features NVTweak provides;

This tweak is intended for use with GeForce/Quadro cards and ForceWare 55.xx - 9x.xx 3D Stereo drivers. NVTweak is not fully compatible with Windows 98/Me or driver versions older than 55.xx. If you do happen to run this tweak with older software, you could get errors at startup! To enable full compatibility, you will need to disable the options that are causing issues with your current setup.

NVTweak allows you to operate a graphics card out of normal specifications by overclocking and/or modifying how the driver operates.  You should always use the overclocking utility with extreme care!  I will not be held responsible for any damage that may result from the improper use of this program.

Download & Installation

Requirements for NVTray (install these first):

Please choose the correct version of the .NET Framework below. Most people should choose 32-bit, unless they have a 64-bit operating system such as Windows x64 Edition. If you use a 64-bit OS, match the version of Framework with your processor's architecture.

32-bit (x86): Microsoft .NET Framework Version 2.0 Redistributable Package (x86)
64-bit (x64): Microsoft .NET Framework Version 2.0 Redistributable Package (x64)
64-bit (IA64): Microsoft .NET Framework Version 2.0 Redistributable Package (IA64)

Download stable:

NVTray 1048 (Caution: this version is outdated, only use it for Win2K/XP and pre-256 series Nvidia drivers)

Download latest beta:

NVTray 1064 Beta for x86 & x64 (for Windows XP/Vista/7 and release 256+ drivers)

NVTray 1051 Beta 4 for x86 || x64 (for Windows 2K/XP and pre-256 series Nvidia drivers)

Note: The beta version above includes a technical preview of the Flash On Screen Display originally developed by Ray Adams of ATI Tray Tools. It can display FPS, GPU Temps (in which I added SLI support), GPU/Memory Clocks in-game, among other useful things. Many thanks to Ray for sharing his wonderful utility, and knowledge!

If you haven't done so already you will need to download and install Microsoft .NET Framework 2.0 before installing NVTray, or the application simply will not work for you. Instructions for installing NVTray are pretty straightforward. Download and start the installation file from above, click next, read and accept the license agreement, choose where you want to install, etcetera. When you're almost done, right before you click finish, it will give you an option to run the program automatically. Remember, when NVTray loads it will start in the system tray, so you won't see any dialogs at least until you double-click the tray icon. Double-clicking the tray icon opens NVTweak v2.0 and then you may begin tweaking to your hearts desire ;-) As a tip, you can close NVTweak by clicking [X] in the upper right corner, and NVTray will still remain in your system tray. Right-clicking the NVTray icon opens a menu similar to the one shown in my screenshot above. Well thats all for now, get to downloading! I hope everyone finds this application as useful as I do. ;o) Enjoy!

Archived Versions:

Note: The following is an old version of NVTweak. It does not require the Microsoft .NET Framework, however it is not compatible with 64-bit systems and is missing many new features that NVTweak 2.0 supports. If you want 64-bit support for NVTweak you should download the newest version of NVTweak (included in the NVTray package above).

Download NVTweak171_install.msi ( ~1.5MB )

After completing setup, NVTweak will open automatically and you may tweak to your liking. Check your NVIDIA properties (you DO NOT have to exit the program or reboot), and you will see many new configurable options in the NVIDIA control panel. To get to these options, right-click on your desktop and go to 'NVIDIA Display' (Win XP/2003).

Optionally, you can import the Quadro nView profiles using the Desktop Management profile manager within the driver itself. Once all of the profiles are imported, use the Desktop Management Wizard to load the profile of your choice. You may be asked to log off and back on again depending on which options you choose.


Press the 'Restore Defaults' button on the NVTweak dialog and exit the program (File > Exit). Remove the NVTweak application by using Add/Remove Programs in the Windows control panel.


Q. I don't see the temperature settings, is this due to my card?
A. The temp settings panel is only available with cards equipped with thermal sensors. Some cards that I know of have temp sensors are 5700U, 5800U, 5950U, and 6800GT/U. But really it all comes down to the manufacturer. I have seen some 5700 and 5900 without temp sensor, but mainly the cheaper XT/LX/SE versions.

Q. The Fan always on doesn't seem to work.
A. The 'fan always on' option is for cards with the OTES (i.e. 5800U) or similar cooling system in which shuts off in 2d mode. It will force fan on even in 2D mode. Of course this means the fans on the HS/F be designed such a way that this option can work.

Q. I thought it enabled OpenGL 2.0? It doesn't though.
A. OpenGL Shading Language 2.0 can only be enabled on 55.xx and higher ForceWare drivers. It had not yet been implemented in older Detonator or pre 55 ForceWare drivers. 6x.xx drivers are GLSL ready, so enabling this option isn't absolutely necessary.

Q. Why does my Operating System report 2x AGP, but my card is 4x/8x?
A.  Ask Microsoft!  This is not a Coolbits or NVIDIA driver bug. 3Dmark and/or Sandra still reports 8x AGP.


I'd like to give a big thanks to everyone at www.nvnews.net and www.mvktech.net for their help and support. Also, Pieter at www.laptopvideo2go.com, for his time and effort in providing us with the latest NVIDIA drivers with modified INF files. And last but certainly not least, The Planet for providing us with fantastic web hosting services. =)
