What is amd_dc_opt.exe?

The genuine amd_dc_opt.exe file is a software component of AMD Dual-Core Optimizer by AMD.
Amd_dc_opt.exe is an executable file that belongs to the AMD Dual-Core Optimizer, a program that helps increase video performance by synchronizing timing effects on dual-core processor systems by regularly adjusting core time-stamp counters. This is not an essential Windows process and can be disabled if known to create problems. AMD Dual-Core Optimizer is only designed for use on Windows XP and is primarily required for high-performance applications and games. Later versions on Windows do not require this software and it may become redundant. Advanced Micro Devices (AMD) is an American corporation that develops solutions in semiconductor technology and its applications in computer processors, motherboards, graphics processors and embedded systems for business and consumer markets. The company was founded in 1969 by Jerry Sanders and is currently based in Sunnyvale, California, United States.

amd dual core optimiser
AMD Dual-Core Optimizer - 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

Best practices for resolving amd_dc_opt issues

A clean and tidy computer is the key requirement for avoiding problems with amd_dc_opt. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the amd_dc_opt.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
