Ok guys I find a compromise that works pretty good for me, but I need to use the settings of the game and Nvidia Inspector. However, the Hud pb is always here but I didn't test to reduce it yet, so I will make the test. I already try to make a 2D portrait instead of 3D but without any improvement. So here's what I've done, be aware that I've made my test with the first tutorial because there are a lot of things here : buildings, animals etc... And to test the better thing is to always take to same scenario.
Note : That will not help you to get rid of these stutters but at least reduce them a few.
Although I use MSI Afterburner to have stats on the game screen with an OSD and see how my rig performs.
Be aware that these settings don't get rid of the stutters but they happen less and they appear more "quickly" (sorry I hope you understand what I mean difficult for me in english sometimes).
On the game settings :
--------------------------
- Res : Full screen 1920 x 1080 60 HZ (important)
- Vertical sync : None (very important I will explain why later).
- Shadow : High
- Shadow Res : 2048
- Shader quality : Standard
- Texture detail : High
- Post processing : High
- Water quality : Low
- Detail scenery : Off (to much demanding for my rig even if I turn off shadows).
- Antialiasing : 4X
- Detail update rate : High
- Use multiple render threads : on
- Use texture streaming : off
- Use PhysX (I have not test with or without so, I will test it later) : off
- Process objects behind camera : off
Now here's the trick. We ask the game to start 1920x1080 at 60 Hz with no vsync that means that the game can run at differents speeds/frequency. Turn Vsync on (half or full) force the game try to get 60 FPS (in this case) that can cause performances issues (on my rig). The problem is that without it, there are a lot of jerks / stutters too because the framerate change everytime (50-55-60-35-40-50-60 and so on). That's why I use Nvidia Inspector that is a program that is more powerfull than the Nvidia Control Panel and let us tweak some things.
There are just 2 things to change. First of all in the Nvidia Inspector :
- Select the right profile that this the "TANE" profile, I don't know why but if I create a new profile for this game that doesn't work so use this one.
- Add the TRS2019 executable to the profile (to make the software apply the settings we are going to make).
Now here's the two tweaks I've done :
- Frame rate limiter : 60 FPS (V2) Choose the V2 option is important because it gives best performances than the 60 FPS regular option.
- Vsync : Fast
And that's all. Very important : click the "apply button" and relaunch totally the game (close the game, and the launcher, and relaunch them, to make the changes applied). Nvidia Inspector is going to tell the game to run max to 60 FPS (to overtake the vsync option we put on "none" in the game settings if you remember, because we don't want to use the "vsync option of the game".
Put "Fast" for the vsync tells the game to use the vsync but in a faster way than (full or half). In this way the game will not try to be to 60 FPS exactly all the time but it will let a "+/-" value that means that sometimes you will be at 60, and sometimes 61-62 or 59, and the vsync will render faster. But be aware that the "Fast" option does not stick your FPS to 60 it's not like a full vsync that's why we use the FPS limiter above that make the job for us, because remember we tell the game settings to do not use "vsync" and without this "framerate limiter" Fast vsync works like a regular vsync (avoid tearing) but without limiting the refresh frequency.
In this way stutters and jerks are always here but happen less often and if they happen, that will be very quick and not should alter you game experience too much.
Now I can profit more and if I have some stutters they happen quickly and they disapear in a second. And in some places of the map I don't have any stutter (I had in these particular places before I make these tweaks).
It's not optimal, it doesn't correct the HUD stuttering problem but it make the game more enjoyable. I've made all these tests without the HUD to not "compromise" the tests because I know that if I display it, I have stutters and jerks. I will look at this HUD pb later and if I can't find anything, may be we will have to wait devs to make a patch for that
I hope these tips will help some people who have these kind of problems like me. It's not perfect but already better

And if you need to, you can ask me to make a little video to explain exactly how these tweaks can be done if you find my explaination not clear.
My Rig :
---------
- 3 HDD SATA 7200 trs/mns (the game is installed on a disk, and the datas (contents) on another disk).
- I5 quad core 6500 3,20 GH
- 16 GB RAM
- MSI Geforce GTX 1060 6 GB
Have a good day and see you soon !
