In a Windows 10 update that will be released "later today," Microsoft is finally adding support for uncapped framerates to apps on the Unified Windows Platform. This update also gives UWP titles support for Nvidia's G-Sync and AMD's FreeSync technologies.
Until today, UWP games were required to use vertical sync, so these two changes are a welcome relief for titles like Gears of War Ultimate Edition. That game was fraught with technical issues when it launched in March, and UWP's limitations did it no favors. The v-sync requirement was a major hurdle for racing fans frustrated with Forza Motorsport 6: Apex, too.
Microsoft does caution that its update alone won't turn on these features in UWP titles. It appears game developers will need to add the necessary switches to turn on these features in their games, too. Redmond does say that Forza Motorsport 6 and Gears of War Ultimate Edition should get support for these features "in the very near future," though.
It's been a rough road for serious gaming on the Unified Windows Platform. Enthusiasts first noted significant issues with gaming on the platform early in March. Not long after, Epic Games' Tim Sweeney made a blistering critique of UWP and Microsoft's attitude toward it. Microsoft's lukewarm response prompted the Unreal creator to lay out his ideas for improving the platform. Today's update is a big step toward parity with the older Win32 API for gaming performance, but there's still a lot of ground to cover.
