Microstutter Graphics

@Kyosos 

i can see your windows version 18363 is out of date , is still ok but it reaches end of support on the 11 May 2021 - see https://docs.microsoft.com/en-us/windows/release-information/

now i can also see your monitor is a 4k gsync monitor although you are running non native lower at 2560 x 1440 

now so saying that one of the first things to check is disable gsync , there is a gsync bug that can occur where fps in any game will lower to like 24fps 

example - https://forum.systemera.net/topic/1038-low-fps-max-24-fps-disabled-gsync-to-fix/ 

So for the Windows version I'll take a closer look, thank you.

Yes I removed the native resolution because someone who tried to help me with my problem told me to do so. I put it back in native in this case.

Ok, I understand that G-sync needs to be disabled but when I go to the Nvidia panel I don't see the ULMB option, is this normal?

@Kyosos 

not sure i have a nvidia 2080 and have that option in the control panel , maybe turn off gsync under "setup gsync"

i am running the same driver version 461.40 as you 

edit - quick google that is Ultra Low Motion Blur. Basically decreases ghosting and motion blur. It's not compatible with G-Sync and can only work at 85, 100, and 120Hz.

so if your monitor doesnt go higher then 60 so likely why yo udont have it

Alright I understand, you think the problem may be with my screen? Should I take a 144hz screen?

@Kyosos 

no not really 

Turn off gsync , play in fullscreen window mode and put shadows to low , see how things are

There is no change, no matter what I do it doesn't change absolutely nothing, I really don't understand where it can come from ... The game is generally smooth but if I do something like fight, put on my mount , open my map ... the game starts to lose control and mini freezes appear, it's quite annoying especially for immersion. I shouldn't have so much trouble running SWTOR ... Someone told me that Swtor uses CPUs badly, could that be?

@Kyosos 

ok the pauses when opening of map and mount etc is more an engine issue then a setting issue

fighting however should be fairly smooth though

@ObsidianVashti 

just to be certain have  you checked the temps you are getting when playing ? generally if its temps though the first few minutes should be ok and then stuttering should get worse 

quick look the temp for the ryzen should be fairly low

I don't really see an increase in temperature, in doubt I have a screen before the fight, and during the fight

Well, I decided to test with my partner's screen, a 1920x1080 screen without G-sync, it turns out that there is absolutely no problem when I play on her screen, the game remains very smooth and no freeze during fights. The problem therefore comes from my screen or the G-sync.

@Kyosos 

I thought we disabled gsync to test ? 

i did find this https://forums.tomshardware.com/threads/acer-xb280hk-gsync-causing-fps-drops.2674835/

Hello! Yes, I deactivated it, the problem is that even by deactivating it it does not work, I still have the mini freeze continuously. Coming back to G-sync, the only way I found to disable it is this (See screenschot)

I just looked at your link, I will test this right away, if I understand correctly they say G-sync not working if V-sync is enabled too? So I have to find a way to turn off V-sync on my pc or do I have to do it directly on my games every time?

He also says that for his games to be smooth he has to set the FPS limit to 57, do you think that's a good idea?

@Kyosos 

yes limiting fps to say 57 or just below 60 has been used for a long time 

Not surprisingly, it doesn't change anything unfortunately. I start to believe that I will never find a solution ... I keep looking with hope
