You can change the default hotkey if it is already used in the game. Some games run with elevated rights so hotkeys tracking may not work. In such cases, consider running this app as an administrator (run second launch option in Steam or create new shortcut with -admin parameter).
Set the desired scale factor. The most commonly used value is '2'. It is well suited for games running full HD resolution on a 4k display or old games running on a full HD display.
Larger values are suitable for low resolution games and displays with large resolutions.
Value '1.5', although not integer, can be useful if the game does not fit on the screen when scaled 2.0x.
The value '1' means no scaling. Choose it if you just want to make game borderless with black bars around it.
This setting changes the resolution of the game so that when it scales, it takes up full screen.
Useful for games that do not allow to set the resolution while in windowed mode (mostly modern games).
Not suitable for games that have fixed resolution (mostly old games).
This setting enables fullscreen anti-aliasing. Affects performance. It is recommended to turn off anti-aliasing in the game if you enable this setting.
This setting is useful for old games where the mouse is not used.
