and... shimmers.

This is Antialiasing Gamma Correction from the Nvidia Control Panel.  Turn this off.  Also turn off Trilinear Optimization, and I have my AF (EDIT) turned off entirely.  I have all shadows off now too.

As far as MSAA... I love it on a pancake screen but I hate it in G2

I'm running FXAA from the Nvidia Panel now.  Works great.  I am finding now that less is more with VR.  It may not be the prettiest, but it's smooth. 

At first I thought, since the rendering engine is deferred (today) that it loves as much AA as you can throw at it in 2D.  So, start with the largest, sharpest image and try not to fuzzy it up with scaling and sharpening.  Then I realized that all that AA was adding tons of fuzz.  So, now I have the sharpest, smoothest DCS, with some aliasing in the usual spots.  My brain will tune them out soon enough.  These are my new hi performance settings for VR.

Trilinear and AF were always off but the gamma correction was on, will try with it turned off. So far I've been very successful letting my brain tune the shimmers out  .

As far as my DCS options go, I've probably tried every combination possible but since I'd been playing SP for the last couple of years, I always end up maxing everything out.  Well... not everything. Heat blur, Sec shadows, MSAA, DoF, Motion blur, all SS's are off.  I keep the shadows on high though. In cockpit they add up a lot of 'feel', although when looking at external models, in form flying for instance, they look like crap.  I stubbornly refuse to compromise on Vis range, always keep it on Extreme. The clouds, I stepped down one notch to high. All sliders to the right,  Gamma on 2.0.  I like 2.2 or 2.3 at night, during midday hrs I prefer 1.7.   I'm still trying to decide on OpenXR since on my current rig, even in SVR I'm getting 90 FPS at high alt and between 55 and 75 when flying over Beirut at low altitude... kinda works for me for now.

Yeah, you don't need to switch to OpenXR.  It brings OpenXRTK which has some nice features, but you are doing great with those numbers.  By AF off, I mean Anisotropic Filtering off in the Game settings.  I think if you set it to off in the NCP it may prevent the game from doing AF.  I have not tested this in ages.  You will be happy with the antialiasing gamma correction setting.  It works in MSFS as well. 

I've tried them all now too, but still learning now and then.  In 2D the performance is so good you can throw everything at it.  VR only started working really well for me in my G2 with the last version of OpenXR.

I meant 'Application Controlled' not OFF for AF in NCP.  Speaking of AF, when set to x2 in NCP while keeping AF in DCS set to x16, I noticed considerably less 'barber pole' type of shimmer when looking at rooftops from certain lighting angles.  I always thought AF in FCP had no effect on in-game AF setting, regardless of 'enhance' or 'override' setting for AA. This was just a spontaneous observation, still have to compare these 2 settings from exactly the same distances and lighting angles before I plaster some happy faces here.

BTW, the AA gamma correction turned off didn't seem to change the 'sparkling' shimmer in my test, at least at first glance. I'll play with it some more later. Anyways... since we're mainly discussing OpenXR in this thread, I've decided to experiment with it a bit when I get a chance, just for the heck of it.

What has any of this got to do with "OpenXR Guide for WMR Headsets"? please take your discussion about NVIDIA settings to a new thread.

Not a damn thing, lol, just one of those spontaneous OT exchanges, that's all. It's done

OpenXR has been running without problems for the past week, but now I'm getting this error. Error as pic attached

Can someone Help please ?

- SteamVR works fine

- Clean DCS Repair

- OpenXR & Tools up to date

 

EDIT: Crazy > Got no C:\projects Folder !???!

EDIT2: OpenXR Demo works fine

EDIT 3: PROBLEM SOLVED, Windows 10 were missing updates.

Can anyone help me understand if I am missing something. I was reviewing the instructions on the first page of this thread and it looks like I am missing a developer took kit. But can't find a link to it anywhere. The first one has the title Open XR Developer tools (I cannot find this program anywhere and the link provided only takes you to the second tool kit which is  Open XR Tools for Windows Mixed Reality. (I have this one. any help would be appreciate.

There is OpenXR Tools for WMR and there is OpenXR Toolkit.  You don't need both, but if you want OpenXR Toolkit, you must first install OpenXR Tools for WMR.  OpenXR Tools for WMR can be found in the Microsoft Store.  OpenXR Toolkit is the one on Github.

There is no dependency on OpenXR Toolkit needing OpenXR Tools for WMR. If you have OpenXR Toolkit, you only really need OpenXR Tools for WMR if you want to enable WMR beta ("Preview runtime").

Also @shambler6691 you should only get OpenXR Tools for WMR if you have a WMR device (eg: HP Reverb). It's not useful with other headsets.

[shambler6691]

Okay, thanks for the help. I currently use WMR with a  HP Reverb 2. I have been using Open Composite, Open XR Tools for WMR and Open XR Toolkit Companion to bypass Steam VR with good results. I was just reviewing this thread the other day and saw on the first page that another addon was identified (Open XR Developer Tool Kit) with photo indicating it should be used. In fact it is mentioned before Open XR Tools. So I was confused as to its use with this type of setup.

IKR.  The OpenXR Developer Tools is an addon for OpenXR, so you can see under the covers.  @mbucchia made the OpenXR Toolkit that gives you scaling, FPS, MR stuffs, etc.  It's all a bit fuzzy to me.

[shambler6691]

Thank you so much for clarifying that for me. I've only been playing DCS for about 10 months now and previously only had experience with PlayStation/Xbox gaming. My PC use was limited to work related programs. It was a steep learning curve that I am sure resulted in mistakes with my setup. Despite this I have DCS running surprisingly well considering all the issues I have read about on this forum, reddit and discord. So I often go back and read through the discussions trying to learn more about them. I really appreciate you taking the time to answer my question. The time and effort put in by this community to create and share mods like this one is very much appreciated.  thank you

Hi everyone,

out of the sudden i do get a crash on dcs when i go replace the openvr_api.dll in the main folder.

Without that file it works on steam vr and open vr but as soon as i replace that it gives me a crash and won't even open the sim, any help?

[beci43]

 

Don't touch it, you don't need to erase anything.
Try running it again with repair.

Hello everyone,

I have a HP Reverb G2 V2 and my pc is an AMD 3700x, RTX 4090 and 32GB DDR4 3600Mhz.

Followed every step on the guide and a few suggestions I found on some pages on this thread. My image is blurry though the fps (locked in openxr) are most of the time at 55.

nullMy settings in game are mostly set to high and have 2x MSAA.

I'm using NIS at 75% with 80% sharpening.

Can anybody offer a suggestion on how to make the game clearer?

 

Thank you!

[tomeye]

I would recommend you disable NIS usage, make sure you set custom render scale at OXR 100%.

What is your PD in DCS?

By PD you mean the IPD in DCS VR Settings? I have it set to 65. Also tried 55 and it's blurry as well.

The biggest thing I noticed, coming from SteamVR to OpenXR is that the image in SteamVR was a lot crispier in a smaller area and a bit blurrier around that area but in OpenXR is blurrier all across (but less blurry than steamVR around its sweetspot).

 

I tried enabling NIS to help with performance but even with it disabled it didn't look good.

[speed-of-heat]

PD (Pixel Density)  it should be set to 1.0 , IPD (terrible name) sort of adjusts the world scale.

if you are getting a lot of blurring, you might need to turn on reprojection,  or go to 60hz on your headset.

[Comante]

hallaghan 

in OpenXr tools, try ENABLE custom render scale and set it 100%
DISABLE nis.

Hello @speed-of-heat

 

I have my PD set to 1.0 and IPD set to 65.

I don't have a performance problem, the game runs above 45fps without any problems.

If I enable reprojection, how would this help? I thought reprojection was meant to help with framerate loss.

 

Thank you for your help.

 

EDIT: Here are my current ingame settings:

reprojection will help with certain kinds of blurring.  for me if i run below the framerate of the headset, i get a blurring externally (its like double vision on everything on the ground) .. if i turn on reprojection, it synthetically generates every other frame, which does produce its own visual artefacts, you need to find out which approach works best for you natural frame rate (60hz, you could likely run now, 90 hz you will have to turn down some settings) or reprojection/motion smoothing or the approach of running as fast as you can at 90hhz , which for me gives the blurring/double vision

In my experience IPD settings within DCS should be the same as your VR device offers / has (if its configurable), because this references the real distance of the center of your eyes, e.g. this explains very well how this works: https://www.vive.com/us/support/cosmos/category_howto/adjusting-the-ipd-on-the-headset.html

So if this doesn't match the real physical distances this may also cause some blurrines and puts additional stress on your eyes.

I believe I read somewhere that IPD in DCS is not the same as the IPD on our VR Headsets. For me, my own IPD is 62 but someone suggested I use 65 in DCS as they aren't related. Can't confirm that one myself.

@speed-of-heat When I ran DCS in steamvr, locked at 45fps with my headset in 90hz, I had no blurriness but since so many people suggested that openxr gives better performance, I switched to try it out but noticed it's blurrier than steamvr.

[speed-of-heat]

i can never just lock my FPS... unless i am locking it above the frame rate of the headset

don't get it twisted... IPD of the headset is NOT the same as IPD in DCS.
