    Unlocked Frame Rate and More Now Enabled for UWP

    What an exciting few months it’s been for Windows 10 Gamers

    In the last few months, we’ve taken Windows 10 gaming to a new level by partnering with Microsoft Studios to deliver marquee titles such as: Gears of War: Ultimate Edition, Rise of the Tomb Raider, Quantum Break, and Forza Motorsport 6: Apex (Beta), all of which support both DirectX 12 and the Universal Windows Platform.

    These titles, along with other key DirectX 12 titles such as Ashes of the Singularity and Hitman, prove that Windows 10 is unequivocally THE place to be for gamers! (By the way, Forza Apex is free, so if you want a zero-cost demonstration of the power of DirectX 12 on your PC, check it out!)

    A big thank you to those who have given us feedback. We read it all – the Window Store reviews, the reviews on gaming-focused websites, and even some of the giant threads on the various forums.

    We’re listening – and acting
    As a direct response to your feedback, we’re excited to announce the release today of new updates to Windows 10 that make gaming even better for game developers and gamers.

    Later today, Windows 10 will be updated with two key new features:

    • Support for AMD’s FreesyncTM and NVIDIA’s G-SYNC™ in Universal Windows Platform games and apps
    • Unlocked frame rate for Universal Windows Platform (UWP) games and apps

    Once applications take advantage of these new features, you will be able to play your UWP games with unlocked frame rates. We expect Gears of War: UE and Forza Motorsport 6: Apex to lead the way by adding this support in the very near future.

    This OS update will be gradually rolled out to all machines, but you can download it directly here.

    These updates to UWP join the already great support for unlocked frame rate and AMD and NVIDIA’s technologies in Windows 10 for classic Windows (Win32) apps.

    Please keep the feedback coming!

    Taking out our crystal ball
    Looking further into the future, you can expect to see some exciting developments on multiple GPUs in DirectX 12 in the near future, and a truly impressive array of DirectX 12 titles later this summer and fall.

    In the meantime, stay tuned to our blog and follow us on Twitter @DirectX12 for a post coming soon about DirectX performance!


    What is the Universal Windows Platform and how does it relate to gaming?
    The focus of this blog is on graphics – for a broader understanding of UWP and gaming, the “Future of Game Development on Windows”, presented last //Build is a good place to start.

    I thought this was the DirectX blog, why are you telling me about the Universal Windows Platform?
    DirectX supports both classic (Win32) apps and Universal Windows Platform apps. App developers who wish to use DirectX 12 can use either Win32 or UWP – we are committed to making them both work great and there should be no performance differences between them.

    From a graphics perspective, how is a Universal Windows App different from a Win32 app?
    For the most part, the Direct3D code in a Universal Windows App is largely the same as a Win32 app. There are some changes to the core Windowing system, which mostly effect how full screen windows work, see “Does DirectX 12 and UWP support full screen exclusive mode” below. There are no performance differences between a DirectX 12 UWP app and a DirectX 12 Win32 app.

    How does “unlocked frame rate” relate to tearing and vsync support? How do these relate to G-SYNC and FreeSync?
    Vsync refers to the ability of an application to synchronize game rendering frames with the refresh rate of the monitor. When you use a game menu to “Disable vsync”, you instruct applications to render frames out of sync with the monitor refresh. Being able to render out of sync with the monitor refresh allows the game to render as fast as the graphics card is capable (unlocked frame rate), but this also means that “tearing” will occur. Tearing occurs when part of two different frames are on the screen at the same time.

    G-SYNC and FreeSync solve the game/monitor synchronization problem by determining when the game is ready to render a new frame. When the game is ready, the graphics driver tells the monitor to refresh the display. This allows your game to render as fast as the graphics card is capable without any tearing, but requires monitors which support adaptive refresh technology.

    Does DirectX 12 and UWP support full screen exclusive mode?
    Full screen exclusive mode was created back in the original release of DirectDraw to provide games with enhanced performance when using the entire screen. The downside of full screen exclusive mode is that it makes the experience for gamers who wish to do other things on their system, such as alt-tab to another application or run the Windows GameDVR, more clunky with excessive flicker and transition time.

    We thought it would be cool if gamers could have the versatility of gaming in a window with the performance of full screen exclusive.

    So, with Windows 10, DirectX 12 games which take up the entire screen perform just as well as the old full screen exclusive mode without any of the full screen exclusive mode disadvantages. This is true for both Win32 and UWP games which use DirectX 12. All of these games can seamlessly alt-tab, run GameDVR, and exhibit normal functionality of a window without any perf degradation vs full screen exclusive.

    Want to know more about how this works? Check out our DirectX 12 Developer Education YouTube channel!

    I have a hybrid laptop (laptop with integrated + discrete GPU), the unlocked framerate doesn’t seem to work for me?
    This is a known issue, and there is additional engineering work underway to enable this as quickly as possible.

    Well, it's a start anyway. It's still rather annoying that I can't backup my game files (Quantum Break is a ridiculous 67 GB download) or use a framerate counter. I get that Microsoft really wants to push UWP, but if they want the platform to succeed with gamers, they're going to have to loosen up the locks quite a bit more.

    This is definitely a couple of significant steps in the right direction. Thanks for that, Microsoft. Thanks needs to also go to those Gears of War UE game devs. Man, they have been taking heat from PC gamers from the get go and still are, mainly due to UWP issues, issues trying to get PC multiplayer matches going, especially given there is no cross platform multiplayer capability in this game. With all the negative feedback on the GOW site, those devs don’t hide, they listen, always respond, keep coming out with patches and still might be the first DX12 title to properly support multi GPU’s. See today’s post below from the devs.

    Sad part is what’s being lost in all this is that GOW UE is a good game, and other than the UWP issues, runs well with Sweeney’s Unreal engine.

    I honestly hope Microsoft succeeds with their PC gaming platform and gives Steam, EA, etc some competition. I don’t see them doing that by simply acquiring exclusive PC titles. They need to go head to head and get rid of the restrictions currently caused by UWP. Ya, PC gaming 101, frame counter, hope they aren’t waiting for a FRAPS update which I don’t think has been updated since 2013. Steam has their own FPS overlay. Ea/Dice, in seconds thanks to a user config I can show FPS, other PC info and limit my frames to anything I want, important to a gamer with a monitor that runs at 60HZ, 100, 120 or 144 which I change depending on the graphic options I choose and related FPS I get.

    IMHO, Microsoft needs to at least match, not restrict what PC gamers have today and then they can talk about their additional treats they can provide with DX12, xbox integration and the fact that they know Windows 10 better than anyone. Competition is good and goes both ways. PC gamers can choose and so can the devs. We have Steam, EA and DICE and Microsoft Studios now with the UWP. I think many of us also saw from the Nvidia Pascal conference the new Doom (another PC gaming legend) running impressively on a Pascal 1080 and on the Vulcan API. Vulcan is DX12’s competition.

    We are pleased you are listening. Bring it on. Expectations are high but after all you are Microsoft.

    At the very least, I'm looking forward to trying out Forza Apex. I definitely do enjoy Forza on my X1.
