I have noticed an FPS reduction in COMPLETE SCREEN mode

when I put citra in full screen reduces the fps - and return to normal screen works perfectly -

Install an external program to put citra in WINDOW WITHOUT BORDER mode -
and the problem was solved - I keep the FPS and a GREAT performance -
(I would like you to implement the BORDER WINDOW mode - since the COMPLETE SCREEN lowers the FPS - (I used a translator to say this - since I speak SPANISH -

In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.
