Top Performance
If you wish to maximize the performance of your system, enable "Top Performance."
Disabled Disable this function. (Default Value)
Enabled Enable Top Performance function.
"Top Performance" will increase H/W working speed. Different system configuration (both H/W
component and OS) will effect the result. For example, the same H/W configuration might not run
properly with Windows XP, but works smoothly with Windows NT. Therefore, if your system is not
perform enough, the reliability or stability problem will appear sometimes, and we will recommend you
disabling the option to avoid the problem as mentioned above.
