Hi Harlan,

I recently read and referred your article "Hardware What?" and have now only realised it was written in 2008.
Does the following still apply to Revit 2010:
"Revit uses OpenGL 1.3 for its graphics generation. This is an open standard that any graphics card can use, so theoretically, if your graphics card is compatible with OpenGL 1.3 you can turn on Hardware acceleration and have a benefit." I have to help someone who needs to disable their graphics acceleration to prevent crashes.

Thanks in advance for taking time to help a poor wee distressed soul... :)

Hi Lynda,

With the 2010 release (and later) Revit has switched from OpenGL to DirectX. It is a different technology for graphic generation. If your card supports DirectX 9 or later, you should be able to use hardware acceleration with Revit 2010. Turning off hardware acceleration though is a good way to troubleshoot if a crash is graphics related. I would recommend taking a look at the certified hardware for Revit and seeing if your card and current driver are listed. The list is for 2011, but it may also help with knowing what driver to try for 2010.
