Remote control

Hi, I would like to use ReShade in a multi-screen setup, where one screen is used to tune the filters of the other one.
Is this possible ? Even better, is there a runtime API to interact with ReShade without using the GUI?

Not natively. You'd have to expand the game window to your second monitor and move the ReShade GUI there. Or alternatively modify the preset files directly and assign a shortcut to reload in the ReShade settings (this will be slower though, since it also recompiles shaders).
