This section includes lists of issues that are either not fixed or not implemented in this version. Some problems listed may not have been thoroughly investigated and, in fact, may not be NVIDIA issues. Others may have workaround solutions.
Open Issues in Version Version 332.21 GeForce 500 series: Deus Ex–there is corruption on the ground in later levels of the game. [871486] GeForce 500 Series: Metro 2033–light bloom increases and decreases throughout the game at light sources such as bulbs, lanterns, or fire. [846214] GeForce GTX 580: HAWX–during the game, an outline of an air plane appears in the upper left corner of the screen after pressing Alt+Tab.
Open Issues in Version Version 332.21 Windows 8 32-bit Issues Single GPU Issues [Video][Notebook] [Internet Explorer] • [YouTube]: The NVIDIA Control Panel video color settings have no effect on YouTube flash video playback within Internet Explorer 10. [999485] • [Stage Video]: Stage Video picture-in-picture content cannot be played within Internet Explorer. [999929] [Video][Notebook] [Hulu Desktop]: When attempting to play videos using Hulu Desktop, there is audio but no video.
Open Issues in Version Version 332.21 Windows 8.1 Issues [3DVision]: While playing a stereoscopic 3D video with stereoscopic 3D enabled, the monitor refresh rate switches to 60 Hz after changing the resolution using the Windows control panel. [1314811] With a 3DTV connected and the resolution set to an HD3D resolution through the NVIDIA Control Panel, the display flickers constantly after installing the driver via INF over driver version 320.49.
Not NVIDIA Issues Not NVIDIA Issues This section lists issues that are not due to the NVIDIA driver as well as features that are not meant to be supported by the NVIDIA driver for Windows Vista/Windows 7.
Not NVIDIA Issues NVIDIA Control Panel Rotate Display Page The rotation radio button labels are changed slightly under Windows 7 to be consistent with the Microsoft panel Table 1.
Not NVIDIA Issues AGP Settings Adjustment Video Zoom Pan & Scan - the process of panning across the desktop in order to display a desktop on a monitor with lower resolution Per-display Desktop Color Setting Adjustments For Clone mode, the desktop color setting adjustments through the NVIDIA Control Panel can only be made across all displays in a system, and not on a per-display basis.
Not NVIDIA Issues • 3ds max 8 (later releases may be supported) • CATIA V5R15 (V5R16 is supported) • PTC’s CDRS 2001 Front buffered rendering may be slow, especially when DWM is enabled. Flushing the rendering queue while rendering to the front buffer may cause the window manager to recomposite. Applications should therefore minimize the frequency with which they flush the rendering queue.
Not NVIDIA Issues World of Warcraft–if you have run the 3D Vision setup wizard, then the game automatically enables 3D stereo even after you disable it. To work around this issue, you must uninstall the 3D Vision driver. Counter Strike–the application crashes to the desktop if the resolution or bit-depth is changed from the in-game video options menu.
Not NVIDIA Issues Flight Simulator X–pressing Alt+Tab to switch to the desktop does not work. [293729] Everquest 2– with NVIDIA driver versions 100.xx, the following error message appears: [273346] “You currently have a (7.15.11.120) video card installed. We recommend that you download version 7772 drivers before playing Everquest.” This occurs because the application is not checking the driver version correctly, but this does not affect game play. Please select “Continue Anyway” to launch the game.
Not NVIDIA Issues GeForce 8800: Ghost Recon - Advanced Warfighter–the gadget side bar bleeds through on the right side of the screen during game play. [281304] GeForce 8800 GTX: Star Wars Battle front 2–screen corruption occurs at 2560x1600 resolution. [325457] GeForce 8800 GTX, GeForce 7900 GTX: Neverwinter Nights 2–the mini map loses its background when the resolution is changed. [273788] GeForce 8800 GTX: Civilization 4–setting in-game 16x antialiasing AA disables all antialiasing.
Not NVIDIA Issues GeForce 8600M GT: Dead Space - a “your graphics card does not meet Dead Space minimum requirement” error message appears after launching the game. [491410] This is a limitation of the application, and only occurs if your monitor does not support 60 Hz refresh rate. GeForce 8600M GT: MPEG1 and MPEG2 playback using iTunes is choppy. [537550] The application does not use hardware acceleration.
Not NVIDIA Issues Operating System Issues Windows Vista Direct-X diagnostics tool (DXDIAG) may report an unexpected value for the display adapter’s memory. [673360] See the Microsoft KB article http://support.microsoft.com/kb/2026022. [SLI], GeForce 8800 GTX: While installing the graphics driver, the message “Incompatible display adapter has been disabled” appears and the display turns blank. [318173] This issue is resolved in Windows 7.
Known Product Limitations Known Product Limitations This section describes problems that will not be fixed. Usually, the source of the problem is beyond the control of NVIDIA. Following is the list of problems and where they are discussed in this document: “Damaged or Missing WMI Service Will Prevent NVIDIA Driver Installation” on page 30 “Screen Turns Black When Performing Clean Overinstall of NVIDIA Drivers on Windows 8.
Known Product Limitations Damaged or Missing WMI Service Will Prevent NVIDIA Driver Installation Issue “Install failed” or “Install Failed, could not find compatible graphics hardware” message may appear during installation, even if the system has a compatible graphics card. This can occur when installing the NVIDIA driver or GeForce Experience software. Cause This issue could be the result of a corrupt WMI service on your system.
Known Product Limitations Resolution This issue does not occur after installing an NVIDIA driver version 326.09 or later for Windows 8.1. When driver version 326.09 or later is installed, performing a clean overinstall with a newer driver will not result in a black screen. Flickering Black Screen Occurs After Installing the NVIDIA Drivers on Windows 8 Issue After installing the NVIDIA drivers on Windows 8, the subsequent reboot results in a black or flickering screen.
Known Product Limitations Total Available Graphics Memory Reported Incorrectly Background–TAG Memory In the Windows Display Driver Model (WDDM), Total Available Graphics (TAG) memory is reported as the sum of • Dedicated Video Memory (video memory dedicated for graphics use) • Dedicated System Memory (system memory dedicated for graphics use), and • Shared System Memory (system memory shared between the graphics subsystem and the CPU).
Known Product Limitations Increasing 4-way SLI/Multi-GPU Performance Issue With some games and applications, you may experience little to no performance gain or even a performance drop with 4-way SLI or multi-GPU configurations. Resolution 1 Open the NVIDIA Control Panel, then click Manage 3D Settings from the navigation pane. 2 Click the Global Settings tab, then scroll to the Power management mode feature, click the corresponding list arrow and select Prefer maximum performance, then click Apply.
Known Product Limitations No PhysX Acceleration Using the GPU If after installing the PhysX System Software you find that there is no PhysX acceleration on supported applications, repeat the PhysX setup as follows: 1 Reboot the PC. 2 Open the NVIDIA Control Panel and then, under 3D Settings, click Set PhysX configuration to open that page. 3 Under Select a PhysX processor, verify that either auto-select or a specific NVIDIA GPU is selected. 4 Click Apply.
Known Product Limitations Do not Use Windows Rollback for Graphics Drivers To reinstall a previous or older NVIDIA graphics driver, do not use the Windows rollback feature. This method will not reliably restore all the previous driver files. Instead, use the Windows Add and Remove programs to remove the current driver, and then install the older driver using setup.exe.
Known Product Limitations Understanding the DirectX Version Shown in the NVIDIA System Information Window The System Information window–accessed by clicking System Information at the bottom left corner of the NVIDIA Control Panel–provides technical information about the NVIDIA graphics cards and driver installed in the system. It also provides information about the Windows version as well as the DirectX version that is installed.
Known Product Limitations Using HDMI Displays that do not Support Audio Some HDMI displays do not support audio, or have issues with GeForce 9 series and earlier, and GeForce GTX 200-series NVIDIA graphics cards. The NVIDIA driver attempts to identify such displays and automatically disables the audio.
Known Product Limitations Using HDMI/DisplayPort Audio in Dualview or Clone Mode Configurations Two Audio-enabled Ports In a multi-display configuration where both HDMI/DisplayPort audio ports are enabled, only the primary display will provide the audio. One Audio-enabled Port In a multi-display configuration where only one audio port is enabled, such as when one display is a DVI display, then the HDMI/DisplayPort display can provide the audio whether is it the primary or secondary display.
Known Product Limitations GPU Runs at a High Performance Level (full clock speeds) in Multi-display Modes This is a hardware limitation with desktop and older notebook GPUs, and not a software bug. When multiple displays are connected and active, the GPU will always operate with full clock speeds in order to efficiently drive multiple displays–even when no 3D programs are running. Note: NVIDIA notebook GeForce 5xxM series and later GPUs do not have this limitation.
Known Product Limitations Gigabyte GA-6BX Motherboard This motherboard uses a LinFinity regulator on the 3.3-V rail that is rated to only 5 A— less than the AGP specification, which requires 6 A. When diagnostics or applications are running, the temperature of the regulator rises, causing the voltage to the NVIDIA chip to drop as low as 2.2 V. Under these circumstances, the regulator cannot supply the current on the 3.3-V rail that the NVIDIA chip requires.
