    FAQ

    1. What should I do if I experience screen flickering immediately upon enabling retouching after installing the Queen SDK plug-in for OBS?

      If screen flickering or stuttering occurs, you can add the Scaling/Aspect Ratio filter to the Effect Filters section and place this filter before the Queen filter. Select a resolution that is smaller than the input resolution of the current source, such as 720×1280.
