In AutoCAD 2009, if you do not pay attention, you will find your professional Quadro graphics card is not in the state of the OPGL certification, this article describes the process to solve this problem. Please follow me and let your Quadro FX360M in the DELL M4300 do its full function.
First, find the problem
My notebook is a DELL mobile workstation, model M4300, the basic configuration of the machine and the display card is as follows:
Table 1 Overall and graphics configuration table 
When using AutoCAD 2009, it was found that the quality of the display graphics is not high, and there are many glitches, as if using a general consumer video card. What is the problem?
Second, find the reason
After you entered "3DCONFIG" in AutoCAD 2009, the problem was noted in the section of the performance checker result log: The 3D device included with the computer was not certified.
From the log analysis, "Current application driver: direct3d9.hdi" shows that although the installation of a professional video card, but only through DirectX certification, not through OPGL certification, in other words, this graphics workstation Quadro FX360M professional graphics Just used as an ordinary consumer graphics card.
To know that graphics workstations are expensive, in addition to stable performance, one of the most important keys is the use of professional graphics such as the NVIDIA Quadro FX360M. If Quadro professional graphics cards are not certified by the OPGL, their performance may not be effective. It can be said that if there is no professional graphics card, it is simply not a graphics workstation.
My analysis has the following possibilities:
One possibility: The wrong version of the driver is displayed. Although it was released by NVIDIA, it has not been modified by Autodesk.
Possibility 2: The display card attribute setting in windows is incorrect, which affects the certification of AutoCAD on the graphics card.
Possibility 3: The display card settings in AutoCAD are incorrect, or there is a conflict with the windows operating system settings.
Third, there is no way to re-doubt
Taking into account the principle of minimizing the impact on the system, because the original Quadro graphics card driver that was certified by Microsoft on the NVIDIA official website was originally used, the solution to this problem may start with the latter two possibilities. Specific steps are as follows:
1, modify the system display properties
Start with the system display settings:
Figure 1 Opening the NVIDIA Control Panel
As shown in Figure 1, first open the NVIDIA Control Panel on the right mouse button, then in the Manage 3D Settings, adjust the global setting to "AUTOCAD" and set options such as "Triple Buffering", "Enable Override Function" to "On" , adjust "Vertical sync" to "Use 3D application settings." Specific figure:
Figure 2 Management 3D Settings in the NVIDIA Control Panel
After completing the changes, enter AutoCAD 2009 to adjust the display properties in AutoCAD.
2, adjust the application properties:
In the Performance Tuner in AutoCAD 2009, although the status of the Direct3D driver is shown as authenticated, its effect is supported as follows:
Although Geometry Acceler, Gusch Shader, and Texture Compression are available, Smooth Line Display and Full Shade Display are not available. OPENGL is displayed as "unauthenticated". It seems that the latter two possibilities have been ruled out because neither the system properties nor the manual adjustment of the display settings in AutoCAD can change the state of the graphics card OPGL authentication.
3, adjust the driver version:
For the first possibility discussed in the previous article, we searched the official websites of NVIDIA and Autodesk respectively. After reviewing, we found that Autodesk has provided users with a compatibility list for their graphics cards. The effect can be divided into four situations from good to bad:
Certified cards only: Certified for Autodesk
Supported, recommended: Supported and recommended
Supported, not recommended: Support but not recommended
Not supported: Not supported
The query and download page is as follows:
Figure 3 Autodesk official website driver query page
In terms of the DELL M4300, Autodesk has prepared the Supported, Recommended level, which is the supported and recommended driver for its own Quadro FX360M. The relevant information is as follows:
Table 2 NVIDIA Quadro FX 360M Driver Information Sheet 
Please note that the above driver is NVIDIA, Autodesk is specifically launched on the DELL M4300 mobile workstation, visible graphics workstation support in the driver is very detailed, because the M4300 is a graphics workstation located in the entry level, but professional equipment and general consumption The difference in equipment is obvious here. The download address for this driver is:
http://download.autodesk.com/prodsupp/inventor/Graphics/nv_mobile/dell/M4300/Quadro%20FX%20360M,%20NVS%20135M, %20NVS%20140M/XP/v.101.19, %20A02%20Post%2006 -15-07/R157636.EXE
As can be seen from the above figure, this driver is designed specifically for the DELL M4300 mobile workstation, immediately download and install the driver, and found that, although in the "3DCONFIG" input in AutoCAD 2009, select the driver version of the performance regulator results log Already changed to 6.104.011.119, but the driver is still unauthenticated and all three possibilities are eliminated.
Now there is a headache. Where is the problem?
IV. Liuyinhuamingyi Village
In order to solve this problem, the author carefully reviewed the problem library on the AUTODESK official website. An article titled "Authentication Hardware XML Database Update" caught my attention. Its address is as follows:
Http://?siteID=1170359&id=11672089
You need to download this file in the following situations:
You have new graphics hardware.
You have a new driver version for graphics hardware in the graphics hardware list.
The graphics card status information in the database has changed. E.g,
The graphics card status changes from "Support" to "Authentication."
The current hardware authentication database version is 17.2.0.3. If your database's local version is older than the current version, your database needs to be updated.
There is no such possibility, although the Quadro FX360M driver version has been officially certified, and the system and AutoCAD2009 settings are correct, but because the hardware database version is too old in AutoCAD2009, can not identify this DELL M4300 belt Quadro FX360 professional graphics?
So immediately go to the Autodesk official website to find the latest authentication hardware database, after download is a zip file called AdskHwCertificationDatabase, after decompression is an xml file named AdskHwCertificationDatabase.xml, apparently, this is a hardware configuration file that comes with AutoCAD Immediately resort to the replacement method, find AdskHwCertificationDatabase.xml file in the AutoCAD2009 installation directory, after the investigation, the file in the C: \ program files \ AutoCAD 2008 \ DRV directory, replace it.
AdskHwCertificationDatabase download address: http://document.e-works.net.cn/rar/65681.htm
Restart AutoCAD2009, enter the 3DCONFIG after the graphics are as follows:

V. Difference between words
The same video card, after certification, in the end how much improvement?
For a complete comparison of the parameters before and after the two, please refer to Table 4 later in this article. Here, only two aspects are compared.
1. In AutoCAD 2009, the state of “full shadow display†was not available, and it has now become available. The support for DirectX after visible authentication has been significantly improved.
2, before showing the authentication status, Quadro FX360M this professional graphics card can only use the D3D settings; and after certification, you can support OPGL, after the manual settings, open its strongest supported display capabilities, between the two The state difference can be seen in the following table:
Table 3 Comparison of main differences before and after certification 
After the authentication status is identified, this Quadro FX360M professional graphics card has changed from “unavailable†to “available†in smooth line display and full shadow display, and the user can adjust the switch status automatically, after opening the AutoCAD smooth line function, The original burrs disappeared. The difference between being unavailable and usable is just a word, but in some scenes the effects are really different.
Although the process of solving professional video card certifications has been turbulent, in the process of searching for information and solving problems, it has been found that the DELL M4300 professional graphics workstation and its own Quadro professional graphics card are indeed quite outstanding. The process of solving the problem is precisely understanding and In the process of learning, I hope this article can help friends who have encountered similar problems.
