The transparent glass effect in Windows 7 looks very nice but on some computers that have underpowered video adapters users will see a performance hit when running the transparent glass effect. Animations are slow and choppy and simple tasks like moving around windows on your screen is not very smooth. One way to speed up Windows 7 and keep the benefits of Aero, such as animations, flip 3D and taskbar thumbnails, is to disable glass transparency.This helps significantly on my Windows 7 netbook that does has a weak integrated graphics chip.
