Microsoft Store games features :
No SLI/Crossfire,
Vsync is always on, (likely 60, since thats dwm vsync)
Game files are protected,
No Exclusive fullscreen (which causes #1, #2)
No fps/hardware monitor software works with it,
You need to take control of the folder as admin if you want access to the exe
Mouse software which lets you create custom binds for each game doesn't work
Games dont run as applications, but run as phone apps
No sweetfx/reshade

MS promises support for PC Games. Releases game but with GFWL 2.0. People don't buy it. MS complains about PC Gamers lack of sales. Rinse and repeat.
Moral of the story - MS never learns.
