It’s been over a year since Windows Vista made its business appearance, and close to a year since it was released for mass consumption. In the meantime it's received a lot of publicity regarding its resource-hungry nature and slower-than-XP performance. While the advent of Vista has driven hardware sales at an impressive pace, for people with older rigs it’s been nothing but bad news.
However, all is not lost. Windows Vista, like previous Windows operating systems, can be tweaked to improve performance. These tweaks can be as simple as a GUI alteration or as complex as editing the registry. With these changes it’s possible to make a laggy Windows Vista rig run more smoothly. Keeping this in mind, we have put together five simple points that can help you to achieve this goal.
Before we start on our quest, allow me to point out that most of these tweaks are freely available on the net. The focus of this article is not to claim that we came up with these tweaks, but to pick the five most effective (from the hundreds out there) and put them together for easier reading.
Tweak Aero
Windows Vista is the first Microsoft OS that sports a fully 3D-accelerated GUI. While the new interface represents a major step forward in eye-candy and usability, it is as expected extremely heavy on the system and requires proper 3D support. On systems that meet its basic requirement the interface looks good. On less than adequate systems, it can be hell. While there is always the option of disabling it, that's not the ideal situation. Instead, simply tone it down.
Here's the easiest way to do this:
1) Disable the Transparent Glass effect. Though the transparent glass effect looks phenomenal, it's a major cause of system lag. This lag can be eliminated by turning off the effect without entirely ruining the Windows Aero look. To do this, head on over to your desktop, right-click anywhere, select Personalize, select Windows Color and Appearance, and uncheck “Enable Transparency”.
2) Another graphical effect that has an adverse effect on the system is the animation of Windows while an application is being maximized or minimized. This too can be toned down. For this, head to Control Panel -> System -> Advanced System Settings -> Advanced -> Performance -> Visual Effects and disable the option “Animate Windows when minimizing or maximizing”.
windows vista is any day better than the XP.
