On mobile and older GPUs from what my google searching has shown running in exclusive mode can reduce latency and increase performance of games. Also with mobile users of certain types of laptops with Nvidia Optimus dedicated cards they have weird tearing when you run games that are not in exclusive mode. Giving the users the option to run in exclusive mode would put us above the unity engine which will crash if you alt tab and somehow forced it into exclusive. Though the one challenge with this is if the user wants to alt tab it isn't going to be as easy but if the user is going to use exclusive mode they should already know this.

[quote=scj643]laptops with Nvidia Optimus dedicated cards they have weird tearing[/quote]
My laptop has this. When i first ran osu! It said that compatiblity mode was force enabled due to nvidia optimus. The game worked fine, however the fps wasn't satisfying (i could barely reach 120fps and there was a notable input lag). I then decided to turn off compatiblity mode off and all of a sudden the game goes super smooth, but i also now have this weird tearing every now and then. It's not really problem since i can play like this, but its somewhat annoying and doesnt look nice.

So if this would solve the problem then you have my support.

If it can properly implement grabbing and locking the display then yes it would.

osu! already has exclusive fullscreen mode (in fact, the options menu even warns you if you aren't in exclusive fullscreen mode on Windows 8/8.1/10). If you're talking about how there's no delay when you alt-tab, that is because the game quick-switches to borderless windowed mode every time you switch windows (this only happens if your screen resolution matches your osu! resolution AFAIK).

Also, just a heads-up: Any performance issues caused by Nvidia Optimus is completely unrelated to whatever you're asking for. Those were known issues with the game itself, and as far as I'm aware, they have been fixed (which is why compatibility mode is no longer forced).

As for the reason why you're getting screen tearing: that is due to the combination of having exclusive fullscreen mode enabled and having framerates much higher than your monitor's refresh rate (most monitors are 60Hz and osu runs at framerates waaaay beyond that).
There's not really much you can do about that besides turning on Vsync (which I would not recommend), or getting a monitor that has a refresh rate high enough to prevent the tearing from distracting you.

This isn't the same type of exclusive fullscreen as AAA titles it's not locking the display since alt tabbing is possible.
