Hey FlashyLatin
To answer your question, every game is different and some games can't run aurora in gaming mode because of the mouse issue, which seems to be on steam's end. I recommend to run it on desktop mode, if the game gives you issues still alt+enter to turn the fullscreen mode to windowed and it should fix it for you. I heard performance is affected but I haven't seen it.

You don't have to keep reading this next part is me just venting about an epiphany I had yesterday.

I don't know what's going on so don't take my comment for fact. But I believe it has to do with how the particular game handles mouse input in fullscreen mode with an overlaid window(since that is kinda what gaming mode does.) Unfortunately, the bypass of using -fullscreen, -borderless, and -windowed commands no longer work. I'm fairly new here so I wasn't around several months ago when they said that using those commands worked, to be honest, I thought it was just dumb luck since when I tried it it didn't work for me. So every time someone asks that question of no mouse on aurora, I answer "go on desktop mode, some games don't work on gaming mode."
But yesterday, when I was trying to find another way to run Uplay/Ubisoft games with aurora I noticed having issues with the mouse input on the aurora screen while Breakpoint ran in fullscreen. I was in desktop mode and alt+tabbing to the aurora window, or even desktop screen, wasn't giving me control of the mouse, the only thing that worked was turning the fullscreen to windowed. So that's when I realized that having overlaid windows running through a single instance/exe/service/whatchamacallit, and the game window happens to be in fullscreen, it could lock you into only being able to use mouse in the fullscreen window(all dependent on how that game handles mouse input) which is what I think is going on with gaming mode.
So long story short, gaming mode runs your game in fullscreen mode and there's currently no way to get around it.

Also, I have found a way to run epic/gog/ubisoft and i would assume any other launcher to work with aurora. It involves adding aurora to steam, launching that, going to the game of your choice and linking the launcher exe to the game's path (instead of the game's exe), then launching the game through that launcher which then lets aurora see the game is running. It's kinda weird since you are using steam to launch aurora, then you use aurora to launch another game launcher, which then finally launches a game. I can go into more detail later I'm still testing things. Hardest thing is linking the launcher exe but once you do its smooth sailing.
