I am disappointed to learn that the [Parallels 10][1] (and earlier) [does not support hardware accelerated 2D (nor 3D) graphics][2] when Mac OS X is the guest OS. 

This means Yosemite inside Parallels runs noticeably slowly in its screen rendering. Menus are delayed when dropping down. Highlighting menu items cannot keep up with the mouse movement. The Dock magnification appears chunky and delayed as you move the mouse across app icons. Windows in the Finder jump an inch or two at a time while dragging to move them. Generally it feels sluggishly delayed similar to screen-sharing over a very slow DSL internet connection.

In contrast, Mountain Lion performs so well in Parallels 9 and 10 that I forget I am using a virtual machine. Really! I set the Dock to the opposite side of the screen to remind myself that I'm using a VM. Apparently the difference is due to a "software emulation of 2D/3D acceleration officially supported by Apple" (per the tech note linked above). Apparently that emulation in provided in Mountain Lion as well, but not Yosemite.

Can anyone verify if [Fusion by VMware][3] (standard edition?, Pro edition?), or [VirtualBox][4] by Oracle, or any other solution can run Yosemite well as a guest OS on a host Mac including peppy graphics? Documenting their support for graphics acceleration would be ideal.

I'm not talking about gaming or running CAD/CAM systems. I asking about normal daily work usage such as email, word processors, text editors, programmers’ IDEs ([IntelliJ][5], [NetBeans][6]), [OmniGroup][7] apps, [LibreOffice][8], Apple Keynote/Pages/Numbers.
