[. . . ] ForceWare Graphics Drivers Release 70 Notes Version 71. 89 For Windows XP / 2000 Windows XP Media Center Edition Windows 98 / ME Windows NT 4. 0 NVIDIA Corporation April 14, 2005 Published by NVIDIA Corporation 2701 San Tomas Expressway Santa Clara, CA 95050 Notice ALL NVIDIA DESIGN SPECIFICATIONS, REFERENCE BOARDS, FILES, DRAWINGS, DIAGNOSTICS, LISTS, AND OTHER DOCUMENTS (TOGETHER AND SEPARATELY, “MATERIALS”) ARE BEING PROVIDED “AS IS. ” NVIDIA MAKES NO WARRANTIES, EXPRESSED, IMPLIED, STATUTORY, OR OTHERWISE WITH RESPECT TO THE MATERIALS, AND EXPRESSLY DISCLAIMS ALL IMPLIED WARRANTIES OF NONINFRINGEMENT, MERCHANTABILITY, AND FITNESS FOR A PARTICULAR PURPOSE.

[. . . ] This change is unnecessary for NVIDIA users, and particularly for users with SLI configurations. For optimal performance when playing World of Warcraft in SLI mode: • Add the ʺ-nofixlagʺ command-line option to your World of Warcraft shortcut, and • Disable ʹvertical syncʹ within the World of Warcraft in-game video options. DVD Playback Issues with Dual Quadro NVS Cards With both AGP and PCI Quadro NVS cards installed in the system, when attempting to play DVDs in full-screen mode on the display connected to the PCI card, the screen is blank. This is not an NVIDIA bug, but rather a problem with older point releases of PowerDVD and WinDVD. PowerDVD 5. 0 Does Not Display Correctly in nView Span Mode With nView Horizontal Span mode enabled, when the PowerDVD 5. 0 playback window is dragged to the second display and then stretched to fill the display, the right area of the display is corrupted. This is not an NVIDIA bug, but a problem with PowerDVD. 12 NVIDIA Corporation Release 70 Version 71. 89 DirectX Fails When Detaching/Reattaching Displays in Dualview Mode This problem can be duplicated as follows: 1 Enable both displays in Dualview mode. 3 Reattach monitor 2 and apply settings. This is not an NVIDIA bug, but a limitation in the operating system where DirectX does not enumerate the second device. DirectX can be restored to both displays by rebooting the system OpenGL Viewport Scaling Problem in Horizontal Span Mode With nView Horizontal Span mode enabled, when opening an OpenGL model in a viewport, the model image is scaled too large to fit in the viewport. The problem occurs with such applications as Maya 5. 0 and 3D Studio MAX 4. 26. This is not an NVIDIA bug, but a limitation in the application’s ability to properly maintain the aspect ratio in Horizontal Span mode. Driver Reports 256 MB Memory on Quadro FX 330 Cards • Problem When a 64 MB Quadro FX 330 card is installed, the driver reports that the card needs 256 MB, causing 256 MB of address space to be consumed. • Explanation This is not a bug but a product limitation. The Quadro FX 330 GPU has some limitations that prevent the card from addressing less than 256 MB of system memory. NVIDIA Corporation 13 Chapter 2: Release 70 Driver Issues Known Product Limitations Video Playback in nView Clone and Span Modes • Problem With nView Clone or Span mode enabled, video playback appears on only one display under the following conditions: • Under nView Clone mode, when fullscreen video mirror is not used. • Under nView Span mode, when fullscreen video mirror is not used and the video is positioned to span across both monitors. • Explanation With applications that render using the hardware overlay—such as DirectX applications—the default driver behavior for Release 60 is to enable the hardware overlay when nView Clone or Span mode is enabled. Because the driver supports only one hardware overlay, the video appears on only one display. Monitor Ordering in the Windows Settings Page Monitor Ordering on a Single GPU • Issue The monitor order in the Display Properties Settings page is not consistently matched with the connectors on the graphics card. • Explanation The driver does not distinguish connector positions, but instead distinguishes the display type, and consequently assigns monitor numbers according to the display type and not according to the connector. 14 NVIDIA Corporation Release 70 Version 71. 89 Monitor Ordering on a Multiple GPU System • Issue When four monitors are connected to a system with multiple PCI GPUs, such as a Quadro NVS 400 graphics card, and enabled in Dualview or Multiview mode, many customers expect the monitor ordering in the Display Properties Settings page to conform to the following: Connector Position Primary GPU—Output 1 Primary GPU—Output 2 Secondary GPU—Output 1 Secondary GPU—Output 2 Monitor Number 1 2 3 4 The monitor ordering, in fact, does not conform to this scheme. • Explanation The monitor ordering is not controlled by the driver, but rather by the Windows OS method of enumerating PCI devices. The Windows enumeration results in the following monitor numbering: Connector Position Primary GPU—Output 1 Seconday GPU—Output 1 Primary GPU—Output 2 Secondary GPU—Output 2 Monitor Number 1 2 3 4 Considerations for nView Span Modes: Outputs from the same GPUs are grouped together in nView Span modes, resulting in the desktop spanning across monitors 1 and 3, or across 2 and 4. NVIDIA Corporation 15 Chapter 2: Release 70 Driver Issues Known Product Limitations DirectX Applications Run Only on Single Display Even in Multiview Mode • Problem When running DirectX applications in fullscreen mode on an NVIDIA Multiview system, the application appears on only one display instead of all the displays. A Multiview system consists of a Quadro NVS series graphics card with multiple monitors connected and multiview mode enabled. • Explanation The problem occurs only with DirectX /Direct3D applications that use fullscreen exclusive mode. In order to support these applications, the driver must switch to single display mode and blank out the other displays. In scenarios that require multiview functionality—such as when using screen savers—NVIDIA recommends using non-DirectX/Direct3D applications. Applying Workstation Application Profiles • Background The workstation application profiles are software settings used by the NVIDIA Display Drivers to provide optimum performance when using a selected application. The profile also works around known application issues and bugs. If there is an available setting for an application, it should be used, otherwise incorrect behavior or reduced performance is likely to occur. [. . . ] For CPUs, it is common for developers to implement code paths specifically optimized for AMD or Intel (e. g MMX and 3DNow!). Because architectures vary, it makes sense that one common assembly language can’t cover all the nuances of specific GPU micro-architectures. In fact, different code paths make different GPUs go faster. As a result with the GeForce FX architecture, NVIDIA has implemented a GPU-specific compiler that can be used to optimize application performance. NVIDIA Corporation 41 CHAPTER 4: NVIDIA Driver History Release 50 Enhancements Display Driver Changes and New Features • Rotation support Added to Windows Me/9x. • Custom resolutions Provides the user with the ability to construct new modes via the NVIDIA control panel. • Screen editing Allows removing infrequently used screens by dragging them from the NVIDIA screen menu to a list.
