Hi,
I'm adding my experience here with this issue.
GPU: 1080 Ti
CPU: i7 6800K 6 cores, 12 threads
RAM: DDR-4 32 GB
OS: Windows 10 Pro 1709 (Redstone 3 Fall Creators Update)
Monitor: G-Sync 144 Hz
Game: Full screen, Ultra, resolution scale 140%
Issues in SWBF2: stuttering in Video Cut-Scenes, in menus, in lootcrates, at the beginning of maps, randomly during play time.
Issues in BF1: stuttering in Video Cut-Scenes (Operations), in real-time rendered Cut-Scenes (Operations), at the beginning of maps.
So way more stuttering in SWBF2 than BF1.
I solved all of them by turning off DX12, one is remaining tho, video pre-rendered Cut-Scenes of Operations in BF1 are still stuttering, but that's all.
I need to mention that for BF1, I'm using: gametime.maxvariablefps 141
141 because I'm following Blur Busters recommendations of setting 3 FPS below refresh rate (144 Hz) to force G-Sync to be always on.
V-sync is OFF in game, and ON in NVIDIA control panel, as recommended by Blur Busters, again to get G-Sync to work as intended with the minimum possible of input lag.
For SWBF2 I could not get gametime.maxvariablefps 141 to work, it's not capping my FPS at 141, whether I use it in in-game console, or config files, launch options, the game is not taking it into account, it's odd.
So for this game, I'm using Riva Turner to cap fps at 141, it adds very little input lag compared to use an in-game frame limiter, so I would really like to make the in-game one to work in this game too eventually.
From what I understood in my research to solve this issue, it could be related to the Windows 10 Redstone 2 Creators Update of last spring (2017), the problem got reported by dozens of gamers from dozens of different games, to Microsoft, they published later a fix in Windows Insider version of W10, that may or may not makes its way to Redstone 4 Update in early 2018 for regular versions of Windows (spring?).
There's a giant topic about it on NVIDIA forums: All games stuttering with FPS drops since Windows 10 Creators Update
Here is the answer of Microsoft, announcing they made a fix as a test in Windows Insider Build: Windows 10 Creator Update leads to frame rate stuttering and slow performance is there a fix?
If you want to install Windows Insider build and report here if it fixed your issue, that might help Dice.
You're gonna tell me, then why before The Last Jedi patch, there was no stuttering. It still could come from Windows, Dice maybe just changed something that triggered this specific Windows issue in the last patch of SWBF2.
In any case, I noticed this stuttering only in 2 of my games, BF1 and SWBF2, and I solved it in both by turning off DX12, which I don't really mind because DX12 doest not bring graphics improvements, just performance improvements.
People said here that Dice didn't acknowledge the issue yet, but they did, some week ago already, in Twitter.
I could be totally wrong, but after reading a lot on this topic, I'm afraid that it's more on Microsoft hands than Dice or NVIDIA.
And Microsoft, while they published a fix on Windows Insider, they are super slow on fixing this issue that got reported already 9 month ago for many recent games.
Anyway, I hope that my feedback will help some players and/or Dice.
