TITLE: AMD Dual-Core Processor Optimizer

VERSION: 1.00 Rev. B
DESCRIPTION:
This package contains the AMD Dual-Core Processor Optimizer for the listed 
desktop models and operating systems. 

The AMD Dual-Core Processor Optimizer can help improve PC gaming video 
performance by compensating for those applications that bypass the Microsoft 
Windows Application Programming Interface (API) for timing by directly using 
the read time stamp counter (RDTSC) instruction.

Applications that rely on RDTSC do not benefit from the logic in the operating 
system to properly account for the affect of power management mechanisms on the 
rate at which a processor core's time stamp counter (TSC) is incremented. The 
AMD Dual-Core Processor Optimizer helps to correct the resulting video 
performance effects or other incorrect timing effects that these applications 
may experience on dual-core processor systems, by periodically adjusting the 
core time stamp counters, so that they are synchronized.
