Hello, I have recently updated Avast to version 17.1.2286 and I noticed the Game Mode in Performance tab. It seems very useful and I am very happy you have decided to add it to avast, great job!
However when I add a games that are not on the list, using the game path, they are appearing in the same tile, replacing the game that has been there previously. This does not happen when I add the game listed in the add game list, they are added as a separate tiles.
I have also noticed that even though the games added via the game path are not visible they are recognised by avast when I start them.
