TrackIR change in 1.2.6

[71st_Mastiff]

New update is out. Can someone test to see if this issue is still present?

Not at game pc for few days.

 

what issue your referring to as I have track ir 4pro and only use the 4.2.39 version and don't have any issues.

[_Dredd]

This whole thread outlines it, but to cut to the chase it's a frame stutter issue with the cockpit view when panning left right of the HUD.

With mouse and trackir, there's a frame stuttering issue when panning slowly. It isn't present in 1.2.5 and only appeared with 1.2.6 and further updates.

It's most noticeably below 60 frames.

[Lange_666]

It's still there, not solved by this update.

 

@ Mastiff: It's noticable at 60 FSP (and beyond) too but the higher the framerate, the smaller the stutter becomes.

Like _Dredd says, it stutters when you move your head left or right, the moment you keep your head still (or put TrackIR into pause mode) the stutter is gone. It's more noticable the faster the terrain passes by. No such thing on 1.2.5.

[howie87]

This really needs sorting out ASAP

[Windsortheater]

Agreed.

 

Why no response from the testing team? They are usually pretty good about communicating when an issue is logged.

[synti]

Seems we just have to keep posting into this thread to get noticed.

 

PRETTY PLEASE: FIX THIS BUG ASAP!

 

It is very annoying and had made me stop playing DCS.

I am not sure what this issue you guys are having is all about, I get the feeling you are saying the head movement using trackIR has stuttering effect?

 

If so I think you should try limiting your maxfps value in Graphics.lua to little bellow your average FPS in game... I have set mine to 29 (in game its showing as 1 FPS more) and it's smooth as usual.

It's great that you don't have the problem, but please listen to what we are saying. The problem we share did not exist in 1.2.5. In fact, I rolled back to 1.2.5 and trackir immediately went back to normal.

 

I wouldn't describe it as a stuttering effect. It makes the animation appear choppy, like an old cartoon.

 

One thing I did notice with 1.2.6 is that my max fps were going beyond my refresh rate. It occurred to me to lower the max fps, and I did, but it did not help.

The issue is everything outside the cockpit suffers from screen tearing/stutter but only WHILE moving your head in game.

 

Head not moving - No stutter.

 

Something changed to cause this in 1.2.6 and it needs changing back.

 

We shouldn't have to fix this ourselves (although many of us have tried and failed).

 

9000 views and the attitude of the testers is still "I don't have this problem, you must be doing something wrong - try this?"

 

How about just admitting that it IS problem and reporting it?

 

Adaptive Vsync, application controlled Vsync, maxfps value - all of these things make no difference.

 

The issue is only occurring during head movement.

 

It is most apparent when looking at a fixed point on the horizon and performing aileron rolls.

 

The horizon jumps/stutters/tears.

 

This was introduced in 1.2.6 and it IS a bug and it NEEDS fixing.

Only in the +/- horizontal plane, the faster the terrain is passing by, the heavier the effect is. And only when you move your head. The moment you keep it steady or put it in pause mode, the stutter is gone.

That doesn't help, the lower the FPS, the higher the jerkyness. I went back from adaptive VSync at half the refreshrate to adaptive VSync with normal refreshrate to reduce the problem. It doesn't solve it but it reduces the stutter distance (<-- difficult to explain what i mean).

 

Like others already pointed out, rolling back to 1.2.5 solves the issue entirely.

 

I'm on 1.2.6 latest update, ain't gonna roll back no more to 1.2.5, why to much work/download everytime and no multi-player either anymore in 1.2.5 (not that it matters much because i read that 1.2.6 MP has a lot of problems again). I did put DCS on hold and only update to see if it's working or not. When not, i will keep it shelved. No more buying new modules either until it's fixed.

[_Dredd]

Is everyone using fullscreen mode here, or windowed.

Let's eliminate this.

 

I'm running fullscreen. Due to SoftTH and multimonitor's.

 

Same with the others, I've tried lua fps changes, vsync changes, view.lua edits. Nothing changes it.

Have cleared all view commands in profiles for all controllers, even disabled cockpit mouse view control.

 

In 1.2.5 the view panning with trackir was smooth, and the terrain appeared to slightly skip or stutter along at low frame rates. Now it's the opposite, at low frames the terrain movement is smooth motion, but panning the view with trackir, the view panning skips/stutters almost every 5 degrees of panning horizontally.

I am using windowed mode, v-sync in game is off, Aero theme is on and I am not disabling it within DCS (disable aero theme is not checked). And I don't know what to tell you... I don't have this issue with my TrackIR. Sure, when FPS is low I notice terrain flying past quickly gives me not smooth image, but this is due to low FPS (you need very high FPS for very fast moving images). Also I might be a tester but geees, I am not the all-knowing god or something... I'm a volunteer user same as everyone else here... and I don't know insides of how the game works, I can only suggest things I think might help and that's about it... lastly I can create bug report for ED but what to put in there? It needs to be replicated by the tester(s) before it can be reported (and find reason why if possible) or some relation at least. Sorry but I can't help more now.

 

EDIT: if I fly different aircraft I get different FPS... F-15C gives me good FPS (goof enough for me) even with 3 screens and 3 viewports... Su-27 is lower FPS... flying MiG's (as they are old 2D pits) and its even better FPS and everything is smooth... so I don't see why this would be TrackIR issue.

Also, is this is specific aircraft or all, consider you might say all but if you own A-10 and Ka-50 for example then keep in mind that you don't own FC3 for example where this might not be an issue, so it would be good to say what you own and in what aircraft you see this?

 

Also please post FPS you see in game

 

EDIT: I'll see if I can find time to get back on 1.2.5 and compare with what we have now to see if I can tell any difference

Fullscreen mode, v-sync in game is off, Aero theme is on.

 

GTX 560Ti

 

50 fps (1440x900)

 

I have this issue on all FC3 aircraft, P-51, A-10C, BS2 and Huey.

 

I do not have combined arms or or the Mi-8 and do not fly the SU25T.

 

I say again - issue not present in 1.2.5 or previous versions.

 

No amount of graphics, vsync or lua tweaking has solved the problem for me.

 

I have experimented with different drivers/settings etc to no avail.

 

As far as I am concerned the problem lies with DCS.

Lol Kuky, we don't blame you, we just wanted a tester with report capability's to look into this thread and we hooked you...(need a fisher smiley here).

BTW, i'm happy (sort of) that TZeer has the same problem. He did already some serious testing regarding object count and the relation to FPS. His work was greatly appreciated so seeing him posting in here he has the same problem gave me a little hope...

 

EDIT: if I fly different aircraft I get different FPS... F-15C gives me good FPS (goof enough for me) even with 3 screens and 3 viewports... Su-27 is lower FPS... flying MiG's (as they are old 2D pits) and its even better FPS and everything is smooth... so I don't see why this would be TrackIR issue.

FPS doesn't matter just as different types of aircraft don't matter. If you don't see it with 1.2.6 you probably will not see any difference regarding 1.2.5.

I had it on my previous system and i just build me a new one, installed the OS, drivers and shit and then DCS and the bug was already there. It makes me believe that everybody has it but doesn't always notice it.

Smooth has not the same meaning for everybody.

I directly see it when something does not run smooth and "always" trade in eye-candy for smoothness. I prefer a barren landscape which passes smooth under my airplane that a landscape with one tree and one house but which goes choppy.

Also, the moment i installed 1.2.6. it was there. I checked everything from drivers up to TrackIR settings etc... only to find no cure. When reverted back to 1.2.5, problem gone. So it can't be something external, the problem code must sit in DCS somewhere.

And, as mentioned, with my new system, al was installed fresh (no driver over driver or updated DCS, no a fresh clean install of 1.2.6 and the problem was directly there. I then reverted back to 1.2.5 and the problem vanished.

 

To anwsers _Dredd's question:

- Full Screen

- FPS: either 60 (VSync) or 30 (adaptive at 1/2 refresh VSync), depending on my graphical settings (read detail).

- Aero: Off

 

I also can confirm that the SU25T suffers from the same problem.

Issue not present in 1.2.5 or on any previous versions.

 

All tweaks and drivers tried, no help whatsoever.

[Kuky]

So far all 3 of you say you use full screen. Can you try windowed mode?

[Fifi]

It makes me believe that everybody has it but doesn't always notice it.

 

I tried to reproduce what you are describing, but i can't see nothing.

Mouving head with TIR5 is fluent at any speed any altitude here...

I tried to mouve very slowly, normal, very fast...all the same.

I don't have huge FPS though. All around +-30 to 40 anytime, but my TIR view doesn't stutter at all.

At least i have same good rendering as in others sims, like ROF for instance, wich is very perf demanding.

Only sim giving me troubles as you described, was COD.

 

I know it won't help you unfortunatly, and can feel your pain dealing with that.

 

PS: I5 @ 3.2, Zotac 580, Win8 64, 8Gb RAM...VSynch on, MSAAX8Q, TSSAA on, everything on max, Aero desabled ingame, all shadows on, resolution 2560x1440...

+ running few mods like Ricardo BS2 cockpit, Enhanced terrain Low'n slow, Peter radio menu clickable, MI8 English black cockpit, SU25 English pit.

On side note i have my TIR5 installed outside of any programfiles with latest drivers (i created new folder C:\TIR5)

Ok, tried in windowed mode and fullscreen mode.

 

No difference.

 

 

And here is the reason I think someone notices it, and someone don't.

 

Personal preferences and your ability to see faster FPS.

 

Example: Me personally can't play with 30FPS. I find it very hard on my eyes. After a while it's uncomfortable. My preference in 60 FPS with Vsync, it's silky smooth and a joy to fly. Others don't see difference between 30 FPS and 60 FPS, as long as it's vsynced.

 

 

 

Anyway, If I keep my head completely still, everything is smooth as silk. As soon as I try to look around I get the same feeling as when your FPS has dropped a little bit. Not by a huge amount, but just enough to be out of sync and giving the impression of stutter.

This very noticeable as you are flying past something and banking over to keep visual contact while you are doing the turn.

 

I also tried setting max FPS to 30, to put it this way, I wanted to claw my eyes out ;)

 

Also tried taking off the Vsync, got so much tearing that it was impossible to make comparison.

So far all 3 of you say you use full screen. Can you try windowed mode?

 

No, still having exactly the same issue in windowed mode.

 

Just to clarify, I'm running DCS with 8GB ram from an SSD as well and it's not a hardware issue as the problem wasn't there in 1.2.5 or before.

 

I also reverted back to 1.2.5 and didn't have the problem.

 

Like others have said, I think everyone probably has it to some extent and hasn't noticed.

 

The game is playable, but to me the experience is vastly inferior to 1.2.5. Some people might not see it as much of an issue, but I value smoothness as a priority and I can definitely see it.

[TZeer]

I'm reverting back to 1.2.5 right now from latest version.

[Fifi]

Forgot to say my lower FPS view is always forward (probably due to dash board instruments). As soon as i move on sides, i gain around 15 FPS...town or no town, airport or not.

[TZeer]

And I'm back to smooth as silk in 1.2.5 again...

[doveman]

Forgot to say my lower FPS view is always forward (probably due to dash board instruments). As soon as i move on sides, i gain around 15 FPS...town or no town, airport or not.

 

Funny, mine tends to be the opposite. 34-40 fps on the ground at the airport, dropping to 21 fps when looking out the side. Flying around it's a bit more variable and seems to drop depending on whether there's a large number of objects (i.e. an airfield) in whichever direction I'm looking.

Strange indeed!...only thing i could say more about frontal view, is i have set panel rendering to 512...

And i'm also surprised (good way) that i don't have FPS drops above towns or any airfield.

I re-tested and yes, my FPS are always increasing looking on sides (middle-up-down, the same) over towns or not!

Same rendering in P51 SU25 KA50 MI8 Huey.
