TrackIR change in 1.2.6

[_Dredd]

I have vsync turned off in game and in nvidia settings. Always have.

[Lange_666]

Nvidia's Adaptive Vsync works really well with DCS. It gives a noticeable improvement smoothing out a lower frame rate when turning your head

Yes it works quite well but it's not the cause, nor the solution for this problem, already tried that.

 

Update: Played around with various settings (shadows etc) but no joy so far.

 

Also, the jittery effect seen when turning my head is not tearing.

Can people please stop talking about two different issues in this thread, I have tearing, but no stutters, so what is it that people really have problems with?

If you have tearing turn on V Sync and triple buffering.

 

Actually that triple buffering on or off might add or remove jitter. You need to test it.

 

 

I always play with V sync on. My monitor is 60Hz monitor and having any FPS above 60 is a waste of GPU power. It is true that forcing GPU to discard frames over 60 sometimes introduce problems but I like it this way because also in games where I need my headtracking or fast mouse moving camera the tearing is annoying without Vsync.

 

On jitter/stutter front:

 

I re-enabled though in my PS3 Eye camera the refresh to 112FPS (yup... as I said is a waste for it too) and seems tracking is a bit smoother (I mean it doesn't bother me at all).

 

Could be a placebo.

112 FPS is maximum before 125 and I don't want 125. I wish I had 120 but I don't.

Higher FPS in headtracking program/camera gives maybe more options to headtracking interface (the dll) and maybe makes tracking smoother.

As I said... could be a placebo.

 

 

Oh and maybe something very important.

 

I had PS3 Eye to 60FPS. But since 1.2.6 each time I set it to 60 (and I have to do that each day when I start the freetrack so I know it for sure) the interface defaults automatically to 59.78FPS (or something). I don't even have that option in freetrack but it gets there automatically. And that discrepancy might be the clue to stutter cause.

@Harrysound...

one thing to try, is set the Threaded Optimisation option, in the NVidia Control Panel, to Off not Auto. (or its equivalent in ATI/ AMD)

 

 

the 59.74 rate is a more than likely a cause of the monitor stutter, Zaelu (which, obviously, is different to a FPS stutter) as some "computer monitors" are actually televisions screens with the television bits removed.

It's not tearing that we are discussing because you would see tearing also when panning around with the view keys. It's some sort of motion stutter when viewing around with TrackIR. Once you keep your head still the motion of the terrain becomes fluid again. In my other sims i don't have this (with the same TrackIR profile) and i didn't have it prior to 1.2.6.

 

Still playing around with some settings, no joy for now...:mad:

[repsol]

I'm also experiencing heavy stuttering now using track ir ( CLOD and ROF is working fine )...

 

This is very frustrating because after updating to the latest beta Nvidia driver the game is running amazingly well without track ir...

 

Almost constant 60 FPS and pretty much no stuttering when the FPS drops below 60...I'm also able to run the game without Vsync enabled (no tearing at all) now...Not possible before for me.

 

However...The terrible track ir performance in 1.26 makes the game more or less unplayable (have gotten used to track ir and find it hard to play without it)...

 

ED, please try to fix this !

After trying quite a bit of setting in game which solved nothing, i started to tune my TrackIR profile. Almost everything i did made it worse and when it didn't make it worse, it just stayed the same which means my TrackIR is pretty well set up for my needs.

 

So with no solution i started thinking of a thing i wouldn't want to do and that is reverting to 1.2.5.

I took the jump this morning and hopla... TrackIR stutter gone, all back swift and smooth when turning my head.

 

I'm gonna stay on 1.2.5 until i read somewhere that this issue is solved.

[-Hammer-]

After reading this thread I turned the Nvidia's Adaptive Vsync on and also set the process priority of TrackIR to high.

 

TrackIR is much smoother now

[Lange_666]

VSync, adaptive or not, has nothing to do with it (it only removes tearing which can be seen as +/- the same effect we are seeing depending on how large the tearing effect is).

 

Setting process priority to high could help a bit but it shouldn't be needed. It worked before 1.2.6. with a setting set to normal, so why not now? Working on the TrackIR profile can also help depending on how it is set up. Just try the difference between one of the default settings "one on one" and "smooth".

 

I wonder if those with no problem have their process priority setting set to high or realtime?

Exactly same experience for me. I rolled back day or two ago and all went smoothly again.

I also rolled back a few days ago. 1.2.5 is much better, trackir view movement is smooth.

 

Lange, I've experimented with process priority in the past. I have never, ever been able to fix a problem by adjusting those settings.

[_Dredd]

So now the question is, how do testers report this as a bug, or at least request what view changes were made that would be th e cause of this, ie fps improvements, in game vsync modifications behind the scenes, view.lua modifications.

Forgive a stupid question...But HOW do you set the process priority of track ir to high ?

 

I would like to try this and see if it helps...Othervise i will go back to 1.25 also...

 

Thanks/ Repsol

[Lange_666]

@ repsol: i don't think it will help but you can always try.

 

- Start Task Manager

- Select the Processes tab

- Look up the TrackIR.exe and right click on it

- In the dropdownmenu you then get select Priority and make your choise.

- Done

[repsol]

Thanks, Lange 666 !

 

I will give this a try...

[repsol]

I changed the priority...It seems to have reduced the stuttering slightely but no where near good enough.

 

I will try 1.25

how do I rollback to the previous version of DCS? thanks

I have two separate DCS installs (1.2.5 and 1.2.6) side by side on the same PC.

 

Track IR performance in 1.2.6 is noticeably worse and I am experiencing the same micro stutters during head movement as others. Very distracting...

 

I think this is a bug.

[Lange_666]

This must happen at your end and has to do something how your Tracjk-IR sees your tracking dots or you system is processing your movement to slow.

-it's definitive not inside of DCS - It's your system and how it's set-up.

@PeterP: How about the above proof? Still convinced it is "at our end"?

[VTJS17_Fire]

I have the same issue. Tried to tune the axis, but I have still the stutters.

Lange_666,

 

what exactly do you expect from me that goes further than this:

 

 

OK- whatever - I don't have it.

I just wanted to point out that it has (whatever it is) nothing to do with the new ShulderSize feature.

 

?

[gavagai]

Into addition to force feedback, I'm waiting for this bug to be addressed before I re-install 1.2.6.

Disable HEADROLL and the head left to right functions in the TIR software? (leaving Tilt, Pan, Zoom only)
