Your desktop will be a rich DX11-based experience, and your virtual GPU should be too

[zigzag3143]

When you take Windows 8 Release Preview home and launch it, you’ll see a rich and immersive experience accelerated by a DX11 desktop. Your VDI solution should focus on bringing all of that to you, all while tackling the challenges of distance and connecting from anywhere.
You’ll want a touch interface, smooth animations that give a tactile feel, and the richest set of applications and compatibility. You’ll want the ecosystem of software, hardware, and the Windows operating system to bring that together.
