So shift + f2 is the default key shortcut to switch between windows, therefore not allowing me to open Reshade menu. I have searched far and wide for a solution, most of which say to go into the ini file or settings file and change the settings, which i cant find for the life of me. dx10+ btw have tried most key combinations i could think of including Fn + Shift + f2
Check the dxgi.ini in your game's exe folder where you installed reshade.
The [input] section is where it's at.
I don't know how it translates to keys but you could use mine and change it later in the ui.
I think it's mapped like this.
