Thank you, i will try that. Did this help People with same issue?
It depends u can try different values from 1-4.
Omfg, this worked!!! But why? What is it actually doing??? Thank you so much !!! I tried so many things
Cool. B) And ure welcome bro. 
Render device command is actually limiting ure rendered frames which can be prepared by ur cpu before ure gpu completes the frame.
Reminder of my problem : fps drop and stutturing sound, look my video at 11 seconds :

To install windows 10 without Creator Update, I created a windows 10 dvd (download iso w10 on Microsoft to create DVD or USB).
And when you install windows, In the end it asks you to make major update (Creator update) and you choice No. And after installation windows, on the widows desktop, a shortcut is created. This shortcut is the Creator Update if you want to do update, so you do not launch this update (Creator Update).
But windows continue tu udpate, but without Creatror Update. My system version windows is 1607
Well that was right at the end maybe caused by ur recording software.
No with Creator Update I only installed recording software (shadowplay) to make this video. Without shadowplay, I also had this problem.
Now, my windows is without creator udpdate and I can use software recording without problem.
OK cool.
Did you disable game mode and game dvr while on the creators update?
but yes of course… software recording and game dvr while, first things I tested omg sériously…
I tested all the drivers nvidia, bios motherboard updated, cpu et gpu no oc, memtest on on cfg I7 4790K, MSI Z97 PC Mate, 16Go ddr3 and cfg I7 7700K, GA-Z270-UD3P, 16Go DDR4…etc. I continue??
I tested twice without Creator Update : game impeccable, fluid game. I install Creator Update : return problems every time.
So now, no Creator Update since two weeks and since two weeks : zero stutturing, zero saccades.
Anyone didn’t have stutters before the BF1 June Update , DICE did something in June Update which causes stutters in CU.
Also I tried with Windows 8.1 clean install and the game is SUPER!! No drops and so fluid! But in Windows 10 CU the game is crappy, with too much cpu usage, fps drops, shutterings
Since that I fix the problem without Creator Update, I take pleasure in playing.
Which driver version r u using.
I7 6700k
GTX970
16G
I have a sharp decline in the number of frames.
What do u mean by sharp decline like drop in frames after joining a server with time. Like memory leak?
Yes, yes, as you say
Can u post a video with fps and graph on and then post it on twitter or reddit.
384.80 from guru3d, but Amiens (around E flag) is quite lagged yet, but in Windows 8.1 is better much less lag than Windows 10 CU
So how do i roll back on NON creator win upadate? somebody have link?
