What is your ingame settings in the toolkit for OXR?

No it doesn't, auto does not enable reprojection for DCS. What you're seeing is the 45hz vsync, it will be smooth facing forwards and for head rotations but not for translating objects (sliding sideways relative to one another).

My description "auto" was missleading here. i meant it automatical locks @45 
also MRP-Overlay tells me -> it is working

Checked again, vsync is definitely off everywhere
but as I said, I don't need MPR anyway unless it brings me an advantage
just tried it out to see if it made my main problem (jitter/stutter when looking sideways) disappears.

will try SVR again to make sure that it only occurs in OXR

Ok, now i'm a bit smarter. It all seems to be a matter of CPU frame times (what a suprise)
Anything over 10ms will cause stuttering. Strangely less present in SVR with a smoother flight feeling, although i have 10FPS less there.

What immediately strikes when switching directly between OXR / SVR is the clarity. Just like back 2 years ago, the difference between Reshade / No Reshade.

Otherwise, as always, nothing has changed. You can throw all your hardware at DCS and it won't change much.
Or.. wait... I would have paid 800 bucks more just for a 4090... forget it! Waiting next 10 years for MC... Vulkan... or throwing a new X3D at it early next year could help 
Until then, i'll continually tweak the settings and/or trying SVR + a reshader again.
In DCS, hope dies last

I found that turning vsync to "fast" in NVidia control panel helped a lot with stutters looking to the sides.

Main Problem is sideview stuttering. Straight forward all is perfect!

2nd prob. is ghosting on moving objects, but that's not so bad.

Turn off that repro-garbo and try your G2 at 60Hz. You may be among those of us fortunate enough to not see the 60Hz flicker.

If so, crank those settings and enjoy.

Without repro was always my first choice as well as my gut feeling.
60Hz sounds good! I'll try this... setup withhin the toolkit, right?
I think / hope i'm not that demanding Thanks!

Hello friends,

after a 1.5 year break due to a lack of hardware, I'm finally back.

Now with a used 10900k and a 3090ti I can fly again. OXR works so far  except... 

I have stuttering and some ghosting on fast objects, especially when looking to the side.  Straight out everything is perfect.

What can it be?

FPS are roughly in the range of 40-90.  Reprojection off or on does not make any significant differences. Resolution in OXRDT 90%. OXRTK not touched so far. Other specs: rog z490, 32gb RAM because 4 dimms are not running ;-(

Greetings from Bavaria

 

I'm having same issues on my Quest2 . Locked 72hz and 1.3 in software but looking outside from side to side I have frames jumping and ground stutters .

Not sure what's causing this . 

VRperfkit works great but openxr I'm getting stutters looking at the ground but Straight ahead works nice .

Also ghosting looking at cannon wingtips , some Thing not right  .

The issue is less visible at lower settings. I think the shown FPS is not the real FPS (in DCS). i mean end-to-end.

I've turned on Vsync in NCP and ASW off and bit rate lowed to match 1.3 in quest2 software .

Lowed my settings in openxr and all was smooth . Going to up scaling in openxr see if stutters come back . 

[speed-of-heat]

Motion Reprojection artefacts. seem to be worse with the latest version of open composite ?

Vsync in VR???
Ok, I did a little research and found this:

I've been around for over 12 years now, and DCS never fails to amaze me with its absolutely strange behavior.

@Sr. Thanks! I´m trying this out now!

Ok, tried it.
Performance was fantastic! No side-view tearing, jitter, stutter whatever... even the ghosting has disappeared.

Unfortunately I see a flicker. But "only" in very bright areas. The pit, terrain, even the sky all looks great but the bright clouds, snow, sun enlightening areas... meh!
But why only in bright areas?
It was a little better on the second flight (getting used to it?) but NO, somehow it doesn't feel good for my brain

Will have no choice tweaking these frametimes out and give repro another chance.

Try a few of the sunglasses effect in the OXR toolkit. Or adjusting gamma.

Like I said, it's a lucky few not affected by the 60Hz flicker.

Is there a requirement to re install ( or uninstall first) openXr from DCS before or after a DCS update? 

[speed-of-heat]

depends ...  if you are using the older installation method copying the DLL to the DCS folder, then depending on the options you choose, it might require a reinstallation.

if you are using the Open Composite Runtime Switcher (OpenXR)  app it shouldn't be required .

in the past there used to be a dll in the DCS directory that needed deleting, but ED removed it relying on the Windows files instead, which the OCRS will manage for you

Not that i know of . Once active i think it stay active . But its easy to switch from openxr to steamvr and back .

What i dont get:

OK, i understood now the Runtime thingy. Switching from Steam to OpenXR or PrimaxXR and back.

But what does that composite thing?

always had stuttering with dcs with hags turned on, just switched to opencomposite and not getting stuttering with dcs anymore.

OpenComposite is a "translation" of what makes this switch from OpenVR to OpenXR possible 

DCS is not able to use OpenXR natively and requires OpenComposite 
MSFS can utilise OpenXR straight out of the box and doesn't need OpenComposite

Here is a screenshot from Mbucchia's excellent FAQ. I recommend reading it fully so you understand what is actually happening: https://mbucchia.github.io/OpenXR-Toolkit/opencomposite.html#what-opencomposite-does

[Eisprinzessin]

Okay, thanks. Now some light comes in my life.

I did some testing. Specs at first:

RTX3080TiProzessor    12th Gen Intel(R) Core(TM) i9-12900K   3.20 GHz
Installierter RAM    128 GB (128 GB verwendbar)
Win11 Home

I switched from G2 to Pimax 8KX

Im running now 90fps with the following settings:

Pimax OpenXR as runtime over Steam

I encountered a massive frame gain when i killed Open Composite and switched to Steam VR. It was a solit 20 FPS +
Anyone else made this experience?

PiTool everything off except FFR (Balanced). Rendering at 1, FOV on normal
Steam VR at 100 %, Ingame 0,9

What i dont get to work is Motion reprojection. I tried it on "Force on" or "always on" but it seem like it is alwyays off. Even if i force some 60 fpsish drops. Any ideas?

I am on 3080ti, i7, 64GB RAM with G2 and I feel it's such a pity to fly without shadows. If VR adds immersion the same stands for proper lighting and shadows. I was flying at 45 fps and after 2.8 I lost 5-10 fps depending the complexity.

[Eisprinzessin]

Hm, i am not finished with trying out, but tbh in the first view i did not see an huge difference shadows on/off.

Btw: I would love to cap my fps at 45. Why ever it is not working via Steam. Any ideas?

Imho shadows @LOW is a must and also completely sufficient. Without shadows there is no life in da pit!
2.8 - had first read the opinions... looks like an 2D update so far That's why I haven't updated yet.
