One of the big complaints about Microsoft's Universal Windows Platform (UWP) is that it lacks a lot of basic features for gamers. Microsoft promised they will work on this and revealed that the upcoming Windows 10 Anniversary Update will let UWP apps disable Vsync, and support for FreeSync and G-Sync will also be available.
In the future, Windows 10 will also receive support for multi-GPU configurations, game mods, and display overlays, but no timeframe was given for these missing features.
[Phil] Spencer says the company will let UWP apps disable vsync and use FreeSync or G-Sync in the Anniversary Update. Spencer also promises more improvements for PC gamers in the future, including multi-GPU support, mods, and display overlays, although no timeframe was given for these changes.
