amd_dc_opt.exe - Description and Recommendation
The AMD Dual-Core Optimizer can help improve
some PC gaming video performance by compensating for those applications
that bypass the Windows API for timing by directly using the RDTSC
(Read Time Stamp Counter) 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 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.
