With advanced graphics available within Revit, the development team is often asked how Revit graphics hardware certification works, and how graphics card manufacturers participate.
Any candidate graphics cards have to meet the minimum requirements of supporting DirectX 11 and Shader Model 3. Any graphics card that does not meet these requirements will not properly display Revit graphics.
For example, some lines (particularly hidden lines) will be missing from models, reducing the reliability of derived drawings created on that computer. If the target computer has a graphics card that does not meet these requirements we recommend turning off hardware acceleration (HA). When HA is disabled, Revit uses Microsoft’s graphics emulation (WARP) instead of the graphics card to produce accurate graphics, at the cost of performance reduction.
Even if a graphics card supports the above requirements, sometimes graphics drivers have bugs that result in incomplete compliance, causing incorrect graphics to be displayed in Revit. If you are experiencing problems with the display of Revit models we suggest trying a more recent graphics driver as the issue may have already been fixed by the manufacturer. Over the years we have identified a number of issues that have been reported by our customers and we have included them in a test suite that can be used to verify the functionality of a graphics card driver.
To test different graphics cards and drivers, the Revit team creates an application containing the test suite and makes the application available to graphics hardware manufacturers like NVIDIA, AMD, and Intel. The manufacturers can then run this application on their graphics card and driver combinations to generate test results. If the results show any issues, the manufacturer can make immediate changes to the drivers and test and repeat until no issues remain.
Once the test results of a card and driver are acceptable, the results are sent back to the Revit team for validation. If we find no anomalies the results are posted to the Autodesk Certified Hardware site.
