DCS now supports OpenXR natively

Or was I not in OpenXR after all?

See my post here:

You were in OpenXR.  Just launch Windows Mixed Reality Portal, leave it running, then launch DCS.  Glad it's working.

Nailed it.  Man that is the bomb... it's like a whole new DCS.

• two shortcuts so I can choose VR or not
• OpenXR with WMR
• OpenXR tools set to 75% custom render scale and latest OpenXR runtime preview
• OpenXR toolkit enabled for DCS, set to 90% FOV (any more and I'm tunneling.), World Scale set to 100% to match my narrow ass IPD.

No studdering anywhere. Much higher performance.  OpenXR added maybe 10%, this probably added another 10%.  I saw 55 to 60 fps when I'm used to 35 and it looks fantastic.

I wonder if it can help out my Leapmotion performance too... I'll have to look into that.

I’ll try. I find core 0 of my 8600k is 100% at all times when I launch dcs. Other cores bounce around but settle around 90% when flying. 

You can also try Process Lasso to control CPU usage. I have DCS, Steam VR and Virtual Desktop CPU priority set to high priority always and DCS restricted to physical (even numbered cores) only. https://bitsum.com/

Must I use open composite if I want to keep openxr toolkit?

You just need to be running OpenXR, be it opencomposite, SteamVR, WMR, Oculus etc runtimes

Ok thank you. 

[Scuby]

I'm interested in this too, only your answer may be interpreted both ways depending how you look at it So, could please you clarify for us if your measured 1ms advantage is on the OpenComposite side or the native OpenXR side? My guess here is that you meant: native OpenXR performance is better than OpenComp. Thanks mate.

Hi mates,

I'm using the valve index and can't get OpenXR running.

I simply do not have the option to switch to OpenXR in the Developer menu of SteamVR.

Thought I don't have to install anything...?!?

What am I missing here???

Are you using steamvr beta or stable? In beta, there's no option anymore, it is simply set and you are correct in thinking that you shouldn't have to do anything. I will check in a second on mine, so far I was running MT only with --force_enable_VR but you can also force openxr if needed.

I assume this line in the log says it's starting in OpenXR:

I've been searching for what people are using in regards to custom render scale in OpenXR but I can't seem to find anything.   In one of the setup guides the guy had it at 90%.  I'm trying to benchmark my setup to see if it is on par with those of you who have been using dcs and openxr for a while.

For those who use OpenXR -

1) What custom render scale percentage do you use?   

2) Are you also setting another scaling inside DCS using the OpenXR toolkit?

3) Assume the majority of people are leaving DCS pixel density at 1 is that correct?

 

Thank you

This is very HMD dependant, what is yours?

My Pimax 8kX is at native (100%) 4k per eye, so everything at 100% or 1.

100% - 1 - CAS at 30% - framelocked at 55fps - Turbo Mode enabled not the new MR turbo.

Hi every body.

I would like to use the native Openxr of DCS but before I used Opencomposite.

Now when I launch DCS with its native OpenXR, nothing happens, the portal of WMR doesn't launch. I can see the app on my desktop and nothing else. I don't have any pictures in my Headset (HP reverb Pro)

I delete all I can of Opencomposite.

If I reinstall Opencomposite, all work perfectly.

Does somebody have an idea ?

Thanks !

I tested it yesterday, Turbo = on and locked frames (45 and 60). The image has a slight "blurre" when you move yor head and is not as smooth (from the cockpit) as with MR=on.

Who prefers what.

You dont need Opencomposite. Use entries in your shortcuts.

Btw. MT or ST version? For ST the native is OpenVR still so you have to force DCS to work with OpenXR.

It’s what my machine likes, I have no blurr- stutters and best clarity I can muster on this rig. I got this combination for the folks at Thuds discord. I quit MR months ago.

Here is the log file.

I erased Opencomposite
OB ST and OB MT work with the native Open XR
But the Stable, now, launch itself with SteamVR even I force the shortcut with  --force_enable_VR --force_OpenXR

OpenXR support hasn't been added to Stable as far as I know.

Yes, I received the same answer on an other forum !
thanks !

Apologies for being stupid, I have no idea what VR Runtime I am using, all I know is that when I start DCS the Oculus app starts, I go to the OcukusDebugTool, Force ASW Off then ON, and everything is honkey dorey, But when I do this in the Multi Threading version my framerate locks to 40 (Rift S) as it does in the non MT version, but looking at the scenery it's a mess.

I have looked through the various release notes to see if this is listed as a known issue but couldn't find anything, thankfully the non MT version still works magnificently, am I alone and do I need to look into these different runtimes or should I just wait for a fix?

Any help appreciated, I did search before asking.
