Just because I'm impatient, I tried to run the v2 trial under Wine, and it actually works great! All I had to do was set up a new 32-bit wineprefix (actually, I'm not sure if the 32-bit was necessary) and install IE8 through winetricks. I've been playing around with it and haven't found any real issues, plus it runs nice and smoothly. So apparently Intel HD4000 graphics is fine. Can't wait for v3. :)

By the way, the model in the screenshot was something I did a few years ago in Rhino 4.
