Aiming at enhancing the quality and robustness of the round-the-corner final release of Windows 7 and Windows Server 2008 R2, Microsoft has done some changes related to RDP7, the new version of the Remote Desktop protocol.
Remote Desktop will eventually use host resources for DirectX 10.1 / DXGI 1.1 and Direct 2D applications, taking into advantage the enhanced bitmap acceleration capabilities in R2. Pre-release versions of Window 7 used client resources to render these types of applications.
GDI applications, media with Windows Media Player, and Aero Glass will continue using the client-side rendering for remote scenarios.
Even though this design change may impact the utilization of CPU and GPU resources on the host side for certain use cases, it provides a consistent approach to remoting multiple types of rich (2D and 3D) content across a broad range of rich and thin client devices.
