Windows XP looks really cool but displaying all the visual items is not recommended and it just waste system resources. By turning off other display settings, it can really increase the performance of your PC.
To optimize the display settings of your Windows XP, just follow these very simple steps:
1. Click the Start button and select Control Panel

2. Double click the System icon
3. Click the Advanced tab.

4. In the Performance box, click Settings
5. Leave only the following checked:
a. Show shadows under menus
b. Show shadows under mouse pointers
c. Show translucent selection triangle
d. Use drop shadows for icon labels on desktop
e. Use visual styles on windows and buttons
f. Smooth edges of screen fonts

6. Finally, click Apply and OK
