I saw this happen with GTAV @meodien0407 and there was something of a workaround which you can try on FIFA.  Go to My Documents and find your FIFA 18 folder, open settings.xml with Notepad. Do a search for the line <VideoCardDescription>.

If anything but the Radeon R5 M335 is listed, copy and save the settings.xml file somewhere else. Now launch the game and it will create a new settings.xml file.
