Autodesk Revit Hardware Certification FAQ

1. What products does the Revit graphics hardware testing cover?

Autodesk Revit Architecture 2011
Autodesk Revit Structure 2011
Autodesk Revit MEP 2011

Autodesk Revit Architecture 2012
Autodesk Revit Structure 2012
Autodesk Revit MEP 2012

2. How do I check to see if Revit is using hardware acceleration?

In Autodesk Revit, click  > Options”.. On the Graphics tab, the Use Hardware Acceleration (Direct3D®)” check box should be selected.

3. Can I set Revit software applications to use hardware acceleration manually if my graphics hardware is not listed?

Yes, if your graphics hardware can support some of the 3D display features in Revit, you can turn on hardware acceleration. Graphics hardware supporting Shader Model version 2.1 is the minimum requirement to enable the hardware acceleration option.

To turn on hardware acceleration in Revit , click > Options”.On the Graphics tab, select the Use Hardware Acceleration (Direct3D®). check box.

4. Where does the list of tested graphics hardware and drivers reside?

The.xml file contains the list of graphics hardware and drivers that have been tested to work with Revit.

2011: the OCAReport.xml file is in the Autodesk Revit 2011 Programs folder.

2012: The AdskHardwareCertificationReport.xml is in the Autodesk Revit 2012 Programs folder

6. How do I locate graphics warning messages?

A warning displays immediately on Revit start-up if there is a problem with the Hardware Acceleration graphics mode. For 2012, all other warnings are located on the Graphics tab in the Options dialog. Click  > Graphics to check whether your graphics hardware may cause display issues in Revit.

For 2011, all other warning will be shown as dialogs on start-up of Revit

What do the warning messages mean?

7. A problem was encountered with the Hardware Acceleration graphics mode.

This warning will appear when Revit determines it is not compatible with the current graphics card and/or driver.

The most common reason for this is that the card and/or driver have been disabled for use with Revit due to instability or graphics problems. Please check the Graphics Hardware List for information on supported cards and drivers. There are cases when the problem can be fixed by updating to a supported driver version.

8. Newer video card driver

This warning indicates that your currently installed graphics card driver is newer than the driver that Autodesk has tested for use with Revit.

The driver may still work, but if you experience display performance problems or visual issues, please try installing the version of the driver that was tested by Autodesk for use with Revit, or turn off Hardware Acceleration. Please refer to the Graphics Hardware List for tested drivers.

9. Older video card driver

10. Unknown video card

This warning displays when the video card is not found in the database and the Shader Modeler is less than 2.0. (as detected by reading the card properties directly)

There are several possible reasons for this:

  • New card or version of a card.
    This may be a new card that has not been tested by Autodesk, or it may be a newer version of a previously tested card. (e.g. GT vs. GTX or GT+ or 9600 vs. 9800).
    Although you received this warning the graphics card may work without any display performance or visual issues.
  • OEM-version of the card.
    Many system vendors manufacture their own version/branding of graphic cards. Many of these cards are equivalent to NVidia GeForce or ATI Radeon graphic cards. We cannot track all of the various names and IDs that a single card may have, so in some cases a card that falls within this category may not be recognized by Revit, although it is possible that an equivalent version of the card was tested with Revit.
  • Mobile card.
    Currently Autodesk is only performing limited verification of Mobile cards. Mobile video cards and drivers are likely to be modified by the system vendors to work most efficiently with their systems. Revit is not able to recognize all modified versions of cards and drivers.

11. Unsupported video card and driver feature

This warning displays when the video card is not found in the database and the Shader Modeler is between 2.0 and 3.0. Revit may work with Hardware Acceleration turned on but some features like Materials, Rendering could experience display issues. It is recommended that the video card be updated to a card that supports Pixel Shader 3.1 or above.

12. Untested Environment

This warning displays when the video card matches one found in the database, but there are no results for the operating system or driver version.

13. Unknown Video Card. Hardware Acceleration disabled

This warning displays when the video card is not found in the database but its feature-capabilities are less than 20. (as detected by reading the card properties directly)

14. Unknown Video Card. Some graphic display effects may not be fully supported

This warning displays when the video card is not found in the database but its feature level capabilities are between 20-30. (as detected by reading the card properties directly)
