Why is Windows 7 running faster than the vista system?

Many people have installed the Windows 7 RC version, and Windows 7 is running faster than the Vista system. What is the reason for Windows 7 to speed up? AnandTech writes that Windows 7 is faster than Vista because Microsoft has given the video card the task of rendering multiple windows and interface thumbnails, while minimizing the burden on the CPU and memory systems. WDDM 1.1 (Windows display-driven model) is not unique in itself, but Microsoft now moves texture content from system memory to graphics memory, so Windows has a lot less memory consumption and may be less than hundreds of MB in extreme situations.

In addition, Microsoft has modified the GDI (Graphics device Interface) interface without altering the driver. When a local window texture is required, the GDI stack is locked so that only one GDI application can access it at the same time. If the GDI stack is rebuilt, the lock state is removed. If multiple GDI applications initiate the command at the same time, it may cause problems in the video card phase.

Therefore, even if the combination of multiple window thumbnail switching effect, relatively poor performance of the computer can also be in the taskbar to achieve rapid multiple window switching.
