 113.2304.14003

 a46ea22 

Note: This runtime must be enabled from the OpenXR Tools for Windows Mixed Reality, under the Settings tab, by toggling Use latest preview OpenXR runtime on.

Changes for Hololens 2:

• Added support for XR_EXT_hand_interaction (cross-vendor implementation of the hand interaction action profile).
• Added support for XR_MSFTX_scene_marker (HoloLens 2 QR code location and recognition).

Changes for Windows Mixed Reality VR:

• Added support for temporal post-processing of motion vectors (same algorithm as Windows Mixed Reality for SteamVR). Improves the quality of motion reprojection.
• Added support for Nvidia Optical Flow as a source of motion vectors. Improves the quality of motion reprojection on Nvidia RTX cards only.
• Added option "Prefer frame rate over latency". This option allows an application to render frames faster at the cost of additional latency. It can be used in conjunction with motion reprojection. This is similar to the so-called "Turbo Mode" in the 3rd party application "OpenXR Toolkit".
• Moved motion reprojection rendering to a high-priority command queue to prevent interference from the application.
• Fixed a hang in Digital Combat Simulator when motion reprojection is enabled.
• Fixed a bug with transparency when using motion reprojection.
• Removed "Automatic" motion reprojection mode (which only meant "Enabled only in Flight Simulator 2020").
• Added options to limit the motion reprojection rate to a specific fractional rate.

General changes:

• Fixed miscellaneous issues and OpenXR conformance issues.

Noticed this has a mention about a Motion Reproduction fix for DCS (hanging)

Thx for HU!

I see, my OXR Tools has version.

How I can update it? Hmmm. 

Edited April 15, 2023 by YoYo

Ok, I found it. Its in MS Store as it was before. Now I have 113.2304.14003v.

Im surprised that updates work here only manually. I see new options too.

Interesting feature for WMR users!

Thanks @mbucchia AGAIN! 

I wonder if reprojection for OXR will work better with less artifacts and latency.

Short test: artifacting with motion reprojection is much, much better than before, if not completely gone! I would say it is on the same level as motion reprojection in SteamVR now! Very good progress!

 

But: If you roll the aircraft it is not as smooth as in SteamVR; I don't know if it is stutter or if stutter is the right word to describe, but it is not as smooth as in SteamVR

Yes, right! I confirm, it's better. It's not like SteamVR (DCS only) still but better.

DCS, MT version:

1/ artifacts from the helicopter rotor (view from the cockpit, pilot position) have completely disappeared, nice!

2/ effect from the propeller, the artifacts are also gone (for example Yak-52), well done

3/ ghosting on fast moving objects (so F3 view - flyby or dogfight) is present still (somehow on SteamVR +OpenVR ghosting here is less, ner no on my 4090, here is present unfortunately)\

MSFS:

1/ the propeller artifact effect is almost gone, looks great!

Thank You @mbucchia !

Do you have stutter / "unsmooth" experience if you roll the plane around the own axis? 

What NVIDIA driver are you using?

No, didnt notice it, 531.41 but Im using mouse only for F2 view.

I didn't notice the other thread containing this update news from the author himself

 

[YoYo]

Optical Flow takes a job!  Nice progress (especially in MSFS ).

Btw. Id like to know what "prefer FPS over latency" does, I dont see any difference ;>.

Didn't mean F2 view with mouse. I am experiencing "stutter" or "unsmoothness" if I am in the cockpit and push the stick left or right and look out of the side window.

Edit: after more tests, the improvement is notable mainly in the handling of repro motion. The update equaled the performance it had previously with steamvr, with the advantage that in some scenarios 1/3 is necessary, like marianas, and it works fine. in the image it is the configuration that I obtained the best. With the optical flow activated I got more jitter/stutering, I have a 3090. thk.!null

Although I found an improvement with this update in the movement reproduction, in my case steamvr is still better, it is very smooth, I hope it continues to be that way.

Same for me! Artifacting is much better now, but steamvr with motion reprojection is still much smoother.

I suggest you try comparing with and without Nvidia Optical Flow enabled. One might be more adapted to your content than the other. You'll need to restart the game when changing that setting.

@mbucchia

Tested in latest multithreading OB / MT

No, I am sorry, but it makes no difference if I use optical flow or if I disable it. Also tried with toolkit loaaded and with toolkit disabled - no difference

Tried with Nvidia 528.49 and the new 531.61 driver. Tried with stock settings and my attached settings.

It is smooth most of the time when you fly straight or fly slow turns, but for me smoothness ends when I roll the plane left or right arround the aircrafts axis and look sidewards. Also there is some strange flicker in the upper part of the displays of my Reverb G2 under some circumstances.

[mbucchia]

It was worth the try between the 2 modes.

TBH what I have learned early on with Motion reprojection is that people will either love it or hate it.

There is no seeking 100% satisfaction with it.

If it doesn't work we'll for you, don't use it.

I'm told that using OpenXR Toolkit or Nvidia options to limit frame rate to 1/2 (eg 45 FPS) without motion reprojection works well. Using a fractional rate like this produces more consistent frame latency and helps with smoothness. Perhaps this is something that can work better than Motion reprojection for you?

[Gripen 4-1]

I will give it a try later. Thanks for your effort!

Have you tried ST? with MT I have worse performance.

[Gripen 4-1]

Same in ST. 

With SteamVR MT works without problems for me. MR is smooth with SteamVR, no stuttering

[TZeer]

Not home atm, but is the "wobbly" artifacts in the MPD`S of the apache gone now with MR activated?

[Underscore]

after some testing.......

Turned on System>display>graphics>Default graphics settings..... Hardware-accel GPU scheduling   (this produced better results in both MT & ST)

MT:

• Best results with Nvidia flow & prefer frame rate both enabled
• However due to the 100% CPU4 issue with mutli thread its still a bit stutterey...... so back to ST

ST:

• Best results with Nvidia flow disabled..... but prefer frame rate enabled
• very smooth gameplay

 

Hope ED fix the MT 100% CPU issue soon as even messing with affinity still is not as smooth as ST

 

 

Also  I think I get better clarity picture in my G2 with the studio driver rather than the game ready..... May be placebo but it seems to be the case for me.... any thoughts as to why that could be?

@mbucchia Thanks for all your talented hardwork / free time work. I’ve read your MSFS post that you did this on your free time and man that’s unheard of these days.

I appreciate it

Hello, what is the studio driver and game ready ? where do you set it ?

[Underscore]

For Nvidia drivers there are 2 options

- Game ready or Studio graphics drivers

 

You can download either from the Nvidia site

 

Seems like the game ready may be optimised but perhaps sacrifice some image quality in the process - just my guess though

 

I have seen no difference in performance between the two
