    Frame-rate throttling != v-sync.

    The first discard frames until previous presentation is completed, the does not process any other frame before the previous presentation is completed.

    A future update will probably allow unleashed framerate on WStore too but there is no EAT.

    Vulkan will still need to deal the driver presentation implementation. If IHV wants to use atomic synchronization despite the code the application is running you cannot do nothing.

    I honestly don't see any big issue here.

    The big issue is with 60Hz monitor where tearing may be preferred by some people. But remember that the compositor was chanage with the November update, there are still very few DX12 games out yet and packing driver takes time (usually 1-3 months).

    Yes but surely Vulcan will support native full screen with variable refresh rates? Maybe dx12 will too but it doesn't look like it currently does from that article

    Quote from the article:

    "...Microsoft shifts developers and hardware vendors into a standard path through the OS compositor rather than bypassing it..."

    so the API that was supposed to grant developers and games more access (to hardware) is now actually restricting it.
    Yes, I know those refer to different things actually but this is nothing short of... I dunno, a bad comedy?

    This and the WinStore and everything. F*ck this, where are my MS-DOS floppy disks...

    DX12 support full-screen with unleashed frame-rate. What we are seeing actually is AMD driver using atomic synchronization to refresh rate avoiding tearing, but even on this case (and I am still sceptical about its correctness since I just verified it happens even when the application does not ask for it) the game will computes the frames like in unleashed frame-rate mode (v-sync off) as is in exclusive mode. The exclusive mode is emulate just to allow OS to display notifications to the user (which are off by default) which require to sync temporary to the desktop refresh rate.

    This is why I want an official response or see to the complete WDDM 2.0 programming guide, since it was told me the complete opposite. And honestly speaking, I believe more the Ms staffs then techs/geeks-websites.

    Drawing conclusions from a game in alpha stage doesn't make much sense.
    I'm 100% sure developers will continue to include v-sync on/off option in Steam releases.

    Microsoft Store with its restrictions is just a big pile of turd.

    I'm hopeful that Vulkan will improve and see wide support from AAA developers. It's tiresome to have DirectX support tied to OS version.

    Gears of War failed release today shows exactly what is is so damn wrong with the windows store. ANd even Rise of the Tomb Raider showed problems.
    Its not looking good.

    I read what you wrote on other site.
    NO,dont wanna support DirectX 11 & nvidia siren song for their single thread queues.

    I will support DirectX 12 & Vulkan,not old tech. :banana:

    And yeah Windows Store is a mess dont buy games from them,just support Steam.

    Sounds like most of the problem are from the Windows store and the restrictions it places on apps/games at the moment. Not really D3D 12. If microsoft is smart they will improve Windows store, esp for game devs. Right now its quite poor. The tomb raider WS store version gets updates much slower than steam.

    The author packs WDDM 2.0/DX12 features/recommendations with restrictions from the Windows Store, in one wonderful clickbait-y package.
    Apart from the Windows Store (which is suicide for any developer except MS, so you'll keep finding your games in Steam), EVERYTHING ELSE mentioned is a good step towards standardization. The only trouble is the developers themselves, who have to be trusted with all these powers.

    The connection of DX12 and the new compositor to the Windows Store, really speak about the quality of the article. I love how his "sources wished to remain anonymous", about facts someone can check with a free download of the Unreal Engine or something.

    Yea, I really can't understand what's the benefit for forcing everything to pass through the OS compositor if games/fullscreen apps have been able to bypass it previously.

    Granted, this is just one game, but acc. to the article what they (and Guru3D) found isn't tied to the game or it's development state in any way but rather WDDM 2.0.

    how is SteamOS right now?
    Should I just start to jump in the wagon ?

    Probably not right now. Last thing I read was that SteamOS games lack 15-50% of the performance of your hardware compared to a win setup with the same components. Maybe that has changed by now, but I guess it needs a bit of time, Vulkan might change that once it's around with most games.

    Pfft article. But yeah windows store needs an overhaul it kind of sucks atm. In general it works ok but it lacks features a lot of em. SteamOS does not sound like the best alternative in the end cause that is another closed ecosystem, and it does not support the same amount of games as "normal steam" and lacks in performance. Oh how poor options we have.

    Only thing I care about is AdaptiveSync. Because while Direct3D implementation is something to be outlived, upgraded and changed, AdaptiveSync is practically as far as technology can go.

    Maybe MS can make Adaptive sync work without exclusive full screen, but how will compositor know what application should actually control AdaptiveSync?

    If question was AdaptiveSync vs. DX12, I would say: "Let DX12 burn".
    Why? What would be better user experience?
    DX12 @144Hz screen showing all EVEN frames as 0.5ms old and all ODD as 6.5ms old and jumping between 72 and 144fps?
    Or DX11 constantly running between 90 and 110 fps while having always same lag from motion to pixel due to Adaptive sync?
