You can change the default hotkey if it is already used in the game.
Useful if hotkey doesn't work with your game. Click the button and activate the game window within 5 seconds. To unscale a game, simply minimize by Alt-Tab combination and click the "Unscale" button.
You can use this option to avoid calculating the scale factor for each game. Calculates the maximum integer scaling factor that can be used to fit the game inside the screen in the case of integer scaling, or exact scaling factor to fit the game fullscreen in case of nearest neighbor or AMD FSR scaling, while maintaining the aspect ratio.
Corresponds to integer scaling. Commonly used type of scaling for the old 2D games or pixel-art games.
Corresponds to nearest neighbor (non-integer) scaling. Please note that using non-integer values may result in image distortion.
Corresponds to AMD FSR 1.0 (FidelityFX Super Resolution) scaling. Is a more GPU demanding type of scaling compared to integer scaling, but produces a higher quality image. Recommended for modern 3D games.
Requires the input image to be well antialiased and noise-free.
'Shapness' allows to set the desired sharpness in a range from 0 (sharpest) to 2.0.
'Capture API' allows to force the GDI capture API (the default is WGC, which may fall back to GDI), which may be slightly faster in some situations.
'Allow Tearing' allows screen tearing, but may help reduce latency. May be useful in competitive games.
'HDR Support' is needed if your game and hardware support HDR output. It consumes a little more GPU computation and twice as much VRAM.
An optimized version of AMD FSR, which is better suited to less powerful GPUs, but has slightly worse quality.
Select the desired scale factor.
It's recommended to use integer scale factors for old 2D games or pixel-art games.
AMD FSR is designed to operate in [1.0 - 2.0] fractional scale factor range.
The value '1' means no scaling. Choose it if you just want to make game borderless with black bars around it.
In some situations, you may want to use a larger integer scale factor, but the game may slightly exceed the height of the screen. With the alignment option you can decide which part of the image will be cropped.
This setting resizes the game window so that it fills the entire screen when scaled. The game may or may not change its resolution when the window is resized.
Useful for games that do not allow to set the resolution in settings while in windowed mode but change it when game window is resized (mostly modern games).
Not suitable for games that have fixed resolution (mostly old games).
This setting enables fullscreen anti-aliasing. Not suitable for AMD FSR.
It is recommended to leave this option enabled to prevent the cursor from leaving the game window. This setting is useful if you have multiple displays and you want to use the system on other monitors while you are playing.
Takes cursor speed into account. Decreases mouse sensitivity so that the cursor speed in the scaled window matches the cursor speed in a true fullscreen window. Due to the fact that Windows allows to use only certain sensitivity values, rounding can be used.
This setting is useful for old games where the mouse is not used.
Enables support for multiple displays in case of integer scaling (you can use the other displays while you play). Multiple display support is implemented through a different API and may be slower.
You can create shortcuts to start and scale the game easily without launching the app and selecting individual settings for each game. Note: only games that run without a launcher are supported (i.e., if launching the .exe file of the game will directly launch the main game window). Lossless Scaling will start minimized.
The value after the argument is default. Possible options are in brackets.
This must be the absolute path to the executable file of the game, enclosed in quotation marks.
Specify this if the game requires special arguments to run.
