I have been having significant problems with stuttering with TrackIR in DCS (but also apparent in Assetto Corsa) - It is most noticeable when looking around with TrackIR. I just purchased a new Gsync 144hz monitor, thinking the culprit might be my old vsync 60hz monitor - But Gsync has just made the problem worse.
The video below captures the problem in part, but for whatever reason the stuttering isn't as apparent in the video - maybe because of the capture/export process. Still it shows how the issue works. It's bad enough, that I need some kind of solution before I can get back into DCS.
In the video, before the framerate locks, you can see it see-saws between 60-150fps, I certainly don't have a low framerate issue. What isn't apparent in the video is tearing, which is happening even with gsync on.
Priority Class - High, Realtime, Normal etc.
Antivirus - Windows, Bitdefender, Avira, Avast, Off.
As it stands, TrackIR is perfectly fluid at 120fps, but below 100fps it has a noticeable "framerate" when looking around - it looks like 30fps.
I want to note that the game itself isn't stuttering or dropping frames, and if I look around using the joystick hats, everything is smooth. TrackIR exclusively is producing this problem in DCS.
I've been trying to replicate this issue and so far have not been able to. I had a few theories, but none of them were able to make it appear. Without it happening, I can't find a way to fix it.
This problem is all around the Internet present. Many people cannot descripe it correctly. There is no solution out there.
Let me create clarity. The problem is Nvidia Gsync technology combined with a display below or equal @100hz running and using a head tracking device like trackir and its software.
The only thing you can do is to switch off Gsync in Nvidia panel, set 60hz in Nvidia panel for your screen and use Vsync in game. You can lock 60fps in some games too. This will give you much smoother head tracking.
Games like DCS have big problems with your combination of hardware with tracking software.
Natural Point should examine this problem. It is present since years. If they will not, there will never be a solution.
Natural Point should get an 100hz Gsync screen and then they can replicate the issue.
Hope they will do some time, because many many gamer got these issue which is killing a lot of immersion and makes it ugly to play.
Sorry for my bad english, but i hope i could help a lot of people with this lines.
All this U have said is really possible baut can u explain why I have not the problem in DCS 2.1?
With the same hardware and same profile?
I am trying to help at least a dozen guys to get that fixed, the problem is as urgent as it was 2016.
Please have a look at this issue, it's very annoying and it haunts our forum.
I have no idea how to help those guys, please jump in and examine the issue deeper.
This problem occure also with ARMA3 and any other game that uses TRACKIR, it's not only DCS related.
Why is Natural point ignoring us completely?
TrackIR 5 has a 120 Hz update frequency. If you run your games at any other frame rates than integer multiples or divisors of 120 (eg 40, 60, 120, 240), they will have a stuttery motion, especially with panning the camera. The proper way to fix this is to limit the frame rate to 60. 120 you can probably not reach consistently. An inferior solution is to increase the smoothing level in the TrackIR software. That will help smooth things, but also increase response times.
