HzSwitch is a quick applcation for changing of the monitor refresh rate.
It will detect available frequencies and will let you create profiles for your applications.
This will get handy for users having 144Hz monitors that dont want to drive the VGA to the maximum while playing simple games that dont even reach 144 FPS or they simply dont support such refresh rates.
You can select your fallback default frequency in options, add profiles to each executable.
All available frequencies are listed also in quick tray popup menu where you can quickly switch them.
The application is free for download here : DOWNLOAD
