I don´t know if you are aware that F12 takes the screenshot with Reshade effects you may have installed, while Ctrl-S will take the shot without the Reshade.
No need to uninstall anything (though I removed Reshade because it was handicapping my frame rate, even others did not experience anything).
And I agree that what Bob and Buzz say it is what it is, respective of rules.

EDIT: Alpen, you are a good guy. Don´t take it personally.
