Battlefield 1 Windows 10 vsync in FullScreen

Question

Windows 10 with newest clean installed drivers xbox dvr off and vsync selected off in Nvidia control panel as well as in game settings but still being vsynced even in full screen mode. I'm using a laptop with Optimus (integrated and discrete gpu) and even in "exclusive full screen" with vsync forced off in both settings and Nvidia control I believe it is windows 10 that is still forcing vsync on.

It can easily be seen if you get the stutters and frame drops during intense moments. With vsync off we should get a consistent Fps albeit with a screen tear instead of a stutter or a frame drop but instead frames are dropping and stuttering occurs which is worse in my opinion. Hopefully there is a way to bypass the windows 10 gui control at least when we select full screen mode ..

So is there a workaround to give battlefield truly exclusive access to the display at least in full-screen mode so I can actually have vsync off? I never thought I would miss screen tearing, but I will take an occasional tear during intense moments when my gpu can't keep up over a stutter or fps drop any day!

Please help in providing a way to assure we can truly turn off vsync in game on Windows 10. Thanks for addressing this concern, the game is great!

Please provide your system information as mentioned in&nbsp;http://answers.ea.com/t5/Technical-Issues/READ-FIRST-How-To-Get-A-Response-To-Your-Technical-Issue/m-p/5636970#U5636970&nbsp;@TyPennyb

Ha, that's a deal! &nbsp;This turned into a far too technical pursuit for something "extremely simple" to obtain on Windows 7 (by avoiding the "Aero" theme desktop). &nbsp; Just simply obtaining an actual "Vsync Off" functionality (complete with the occasional screen tear - so what) would eliminate the dropping frames/input lag. &nbsp;

..although now Windows 10 users&nbsp;need a way around the DWM. &nbsp;I'm guessing there's some clever whippersnapper out there in the community that can beat the devs to it (assuming of course that developers actually "want" to give us poor users a shot at joining in with our "less than cutting edge" hardware). &nbsp;I understand it's a business, but hey, people on older hardware pay the same price for&nbsp;the same software after all; &nbsp;so the more sales the better right?

update: Buyer Beware! If considering Optimus capable Laptops; or Current Users on/considering Windows 10.

Article was released on May 10, 2016:

"The developers of individual games and apps must now update their software to take advantage of the new options. Microsoft also noted that unlocked frame rates aren't currently working in laptops that have both integrated video and a discrete graphics chip."

There you have it; if your device has integrated/discrete gpu you will be unable to have a truly unlocked frame rate on Windows 10. Not good. Hopefully EA can put some requests in to microsoft to address these types of issues for "all" their users (and therefore not clog up the battlefield/EA forums with issues that end up actually being beyond their control. Thought Win 10 was marketed as a gaming friendly platform. As the heading says, "buyer beware".

thanks for reply, but windows 10 is the system info you need my friend. &nbsp;

here's some background info if you truly wanted more detail,, it's been a well-documented issue. &nbsp;we need &nbsp;way &nbsp;for bf1 to be given exclusive access to our display in full screen and bypass the DWM if we are ever to have the vsync option mean anything on a Windows 10 platform. &nbsp;

that thread links to more info. &nbsp;More than a dxdiag could provide.

Seems there is such a thing in the development world to bypass DWM and its vsync intrusion. "independent flip" and was mentioned here:

https://m.reddit.com/r/GlobalOffensive/comments/38qqju/borderless_window_fix_for_input_lag_and/?ref=search_posts

Another site for developers mentions yet another variation of this called "Immediate flip immediate mode" summarized from here:

http://www.gamedev.net/topic/676986-true-immediate-independent-flip-mode/

It says ,
"Immediate flip immediate mode is the replacement of the fullscreen exclusive mode. The behaviour is almost the same: DWM bypassing, unleashed frame-rate and possible tearing. The main difference is the "non-exclusive" mode: this allow fast alt-tabbing and desktop switch, as well as the having OS notification (if allowed by the user) and elements over-focused the main application (like volume control). In the last scenario the presented frames are temporarily synchronized with the desktop refresh rate until the OS element disappear from the screen (the other frames are automatically discarded).

To enter in fullscreen immediate mode you need to call setfullscreenstate( true) and manually handling WM_SIZE meessage calling resizebuffer(). Current AMD driver should still use DWM composition, so it may not work as expected..

edit: here is an example how to handle fullscreen transitions: https://github.com/Microsoft/DirectX-Graphics-Samples (see D3D12Fullscreen) "

So, can we get this kind of DWM or composition bypass on BF1 so that we may have a true vsync/buffer free option?

I appreciate you taking the time to read this post.
