Mouse wasn't responding 100% correctly in Windows 8.1, e.g. when dragging windows around, it behaved as if the mouse button was not pressed all the time. All fine after I disabled this. Not the 1st time I've had problems with AMD software.

Makes my mouse lag, along with HydraDM64
Sets a global mousehook which can cause problems if you are developing an atl activex control.

Hydravision Desktop Manager. Completely safe, if you think otherwise then you are highly uneducated.

You can disable it from the Catalyst Control Center (new tab named "Hydravision"). Disabling will close the .EXE files automatically.
ATI process for dual screens or triple screens
Screen reftreh serously effected after installation. Returned to normal after uninstall.
ATI's Hydra Vision allows you to manage multiple virtual desktops, and and individual desktop management settings for applications. Similar to the nview application of nvidia

Best practices for resolving HydraDM issues

A clean and tidy computer is the key requirement for avoiding problems with HydraDM. 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 doing a repair of your installation, or in the case of Windows 8, 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 HydraDM.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.
