Revit 2015 is reading the wrong video driver

[AmbroseEngineering]

Dell Precision Mobile Workstation M4600, NVIDIA K1000M video card, 16GB RAM, Windows 7 Professional. Revit 2015 reading the video card driver several steps below installed (I installed the certified driver after installing Revit 2015). Attaschments show the system reading and the Revit 2015 reading.

Tried to uninstall the video driver and then install the recommended one, with all required restarts, etc. - did not work.

What steps are needed to make Revit 2015 recognize the installed driver?

Thank you.

If you are, indeed, using the certified driver (which it appears that you are) then you can ignore any warning you receive in the applications graphics card properties.  Since you are running the software with all graphic features fully enabled, you are good to go.  The warning box is just a notification and is only run by a simple XML file, so it is not actually inhibiting anything.  What you are likely experiencing is just an anomaly.  Autodesk certifies certain drivers, but the general consensus is that all WHQL certified drivers are acceptable anyway.  This type of issue used to be more prominent years ago, but I can assure you that you are fine. 

My only recommendation for mobile cards is that you disable any Optimus BIOS setting for the onboard graphics card (if applicable) and that when you install your driver, you do so by checking the clean installation box.  I have outlined the best practices in my Disable Optimus link in my signature.  Hope that helps.

Thank you! Should I then disable hardware acceleration in the Graphics option for Revit 2015 and let the video driver handle it, or just leave everything as is?

Thank you again,

Since you are using the certified driver, hardware acceleration should work as expected - regardless of what the Autodesk xml file is reporting.  You might as well leave it on until you experience issues.  Good Luck!

You may also want to look at your NVIDIA Control Panel.  You can make sure that Revit is using the NVIDIA Driver instead of the on-board graphics.  I've seen this happen with a couple of other programs where it defaulted to the on-board graphics.

Look in the "Manage 3D Settings" in the NVIDIA Control Panel and look at the "Program Settings" tab.  Then tell Revit to use the "High Performance NVIDIA Processor."
