While tromping through the ATI Catalyst driver problem I had the sudden insight that I shouldn't be using my ATI card (an aged Radeon HD 4300 series) at all but rather the Intel HD option provided by my i7-2600k processor.
When I right clicked on the Diablo 3 icon there was no option to "Run with Virtu" as I had seen with Mass Effect 3 and other titles.
What is the correct method for getting Virtu to take over and give me a graphics boost?

If you open the Lucid Virtu control panel, there is an 'Applications' tab. I added the path to "Diablo III.exe", then selected the "D" column as well as checked the "H" box.
I think D is for Discrete graphics (your Radeon) and I is for Integrated (the Intel HD). H is probably the Lucid "Hyperformance", which is supposed to let both cards work together.
So, for what you're asking: Select the I button and don't check the H box. If I'm understanding it right, that should make Virtu run only on your Intel HD graphics.
