NVIDIA ForceWare 190.38 BETA Graphics Drivers With Power Management Capabilities

NVIDIA ForceWare Graphics Drivers

NVIDIA has just released a new set of graphics drivers in beta version for GeForce 6, 7, 8, 9, 100, and 200-series desktop GPUs and ION GPUs. This driver also installs PhysX runtimes 9.09.0428.


Here are some quick specifications (extracted from GPU Caps Viewer) of this new ForceWare 190.38:

  • Drivers Version: Forceware (7-14-2009)
  • OpenGL Version: 3.1.0
  • GLSL (OpenGL Shading Language) Version: 1.40 NVIDIA via Cg compiler
  • OpenGL Extensions: 183 (on my GTS 250) or 184 (on a GTX 280). See the ForceWare 190.15 OpenGL Extensions List for more details.
    • ForceWare 190.38 + GPU Caps Viewer


      • Adds support for OpenGL 3.1 (like in ForceWare 190.15)
      • Adds support for CUDA 2.3 for improved performance in GPU Computing applications.
      • Adds a new user-controlled power management setting for GeForce 9-series and later graphics cards. This option allows users to set a performance level for each DirectX or OpenGL application. Only for Vista and Seven.
      • Includes several new control panel features and numerous bug fixes. More information can be found in the release documentation.

      Power Management mode (only for Vista and Seven)
      Many NVIDIA graphics cards support multiple performance levels so that the PC can save power when full graphics performance is not required. To provide more control over these power management capabilities, NVIDIA has added the Power Management Mode control. The control consists of two settings: Adaptive and Prefer Maximum Performance.

      • 1/ Adaptive: This is the default setting in which the graphics card monitors GPU usage and seamlessly switches between modes based on the performance demands of the application. This allows the GPU to always use the minimum amount of power required to run a given application, and can allow even older 3D games to run in lower power modes if the game does not require full 3D performance. NVIDIA recommends this setting for best overall balance of power and
      • 2/ Prefer Maximum Performance: This setting lets you maintain the card at its maximum performance level when 3D applications are running regardless of GPU usage. This option can be set Globally (for all 3D applications), or an application profile can be created under Program Settings to set the preference for a particular 3D application. This feature is supported only on select GeForce 9 Series and later GPUs and applies
        only to DirectX and OpenGL‐based applications

      The upcoming CPU-Z 1.52 displays the different performance levels in the Graphics tab.

    Which OpenGL extension present only for GTX 280? As NVIDIA OpenGL documentation is outdated a bit.
