1. Turn off the shaking reduction (set to 0%) may give a tiny boost. I found whatever it was set to made no difference so turned it off. Initially I thought it reduced the wobble in the menus when I set it to 0% but not convinced now.

I was playing around with the shake reduction slider, and it may be that I'm running FSR instead of NIS but, with MR enabled, moving the slider causes the artifacting and jello effect to spike exponentially. Seems to do the opposite of what I though I'd read. So I leave it at default.

Good catch, I'll test that later and update my guide if applicable. I've been getting pretty crappy reprojection artifacts when I've been testing with it and I know I've got 40% shake reduction on (for no particular reason), it would be good if it's a simple thing to clean up the wobbles.

The change can be seen in real time.

When I was testing it out, I was in the FA-18, watching the UFC.

Yes! I too discovered this yesterday. I had the mission start menu displayed and went straight into the OpenXR tookit settings. I was trying to see what effect the shake reduction had but I saw no difference between -200% and 0%. Except.... I swear the wobble on the menu reduced. So I turned it off completely and the wobble seems to have reduced. It's not completely gone but seems a big difference. I am running with NIS and MR enabled.

[edmuss]

The menus currently always wobble with OXR MR because there is no depth buffer information.

I should add that I meant after turning it off the wobble on buildings on 3-9 line had greatly reduced.

Toolkit, on the third tab I think.

Wow... I just went back in to check. 
With MR on it's jello/wobble city. With MR disabled, there's no jello/wobble BUT...

I noticed the cursor with PointCtrl is MUCH more stable and easier to utilize the Apache KU. I had been sort of struggling with it and thinking it was just my left hand not being as steady but it turns out head movement has a lot to do with it.

 

I would point the cursor at the Apache KU and intentionally wiggle my head trying to make it wobble off of the number pad and it wobbled a tiny bit but never jumped completely off the numbers. Then checked again with MR on and the shake reduction moving beyond 0 would cause the slightest head jiggling to make the cursor wiggle and dance of target.

If you are using PointCtrl, give this a shot.

[Sr.]

Wow again... Just determined the best benefit of using the shake reduction set to 100% (at least if you're NOT using MR) is the gun reticle through the Pilot monocle is rock solid!

Score one for targeting/shooting accuracy!

MR on MR off...  Are you folks referring to WMR?  or some other setting?

[hawk4me]

So, still to answer my original question. Does this work only if you have a WMR headset such as g2, reverb? I use a PiMax and WMR as far as I know doesn't work with it.

Everything here is based on installing "OpenXR Tools for Windows Mixed Reality".

So, if your headset doesn't use Windows Mixed Reality, none of this will apply.

[edmuss]

That's not entirely true, both oculus and varjo are able to this and have nothing to do with WMR; they do both support openxr natively though which the pimax does not (I think).

It may be possible to get it to work but I think it still needs to run through steamvr and you'll not see the benefit like the openxr native headsets do.

Well, I see that many people are very happy with the performance obtained, that has made me do tests and more tests and I can't get better performance than with steam vr. My setups are I9 9900k 5ghz, 32gb 3200, nvidia 3090 (driver 512.15), windows 11 (updated daily), hp reverb g1, no hyper threading, no hags, dcs installed on ssd. Same setup (pd 1.0, steamvr 100%) as dcs with steam vr plays at 45fps (reprojection) with very little ghosting in fast motion. Same setup with openxr, playback drops to 30fps. Therefore I already have a problem, having to lower the settings to be able to get 45fps in relation to steam vr is no longer an improvement. I've done all the testing I can and I don't get the openxr performance that everyone talks about. 
I have even come to install windows 11 again and only dcs.

I just found another setting that has improved things even more for me. I can now have clouds at ultra instead of standard..... and the change was.... using XMP memory settings instead of the default auto ones in my bios. Doh! I can't believe that I have missed that for a year since building this rig! So now running at 3600MHz instead of 2600. What an klutz!

I may give "MR off" a try next or try higher level of shadows. But... I like MSAAx4... for me it has got rid of the shimmering.

I've read reports that Win11 causes problems with this mod.  But moreover it doesn't seem like many people with 3090 love it all that much.  Perhaps a testament to your VRAM bandwidth, which is pretty awesome when you think about it.  

[slughead]

Working just fine on Windows 11 for me.

Not true, loving it with my 3090.  Not going back to SteamVR.  OpenXR and the Toolkit working great.

OpenXR toolkit Beta-3 v1.0.4 (newer version drops my FPS)

I also went back to 1.0.4 as my current campaign gave me bad performance. I was wondering its the campaigns fault. But with 1.0.4 the performance is at least 50% better than with 1.0.5.

I also changed the clouds from ultra back to normal but according to legend this does not make a performance difference in VR

EDIT: Oh apparently VR cloud quality settings DO affect performance quite heavily. Someone here said they dont... Need to do more testing.

My system is just over three years old, built it in 2019.  It's a i9-9900x @ 4.1 on all cores and 4.5 on the "fast" cores.  I'm running a 3090 that I'll be swapping for a 3090Ti soon.  3090 will go to my wife's system and replace her 2080Ti.

I've been using Process Lasso for some time now, recommended at one point or another in the optimization guides.  At the time it was recommended to set the CPU affinity to DCS to the threads of the two performance cores on this generation of CPU's.  So, that's what I've been doing for a long time.  Running DCS on four threads, that fastest four.  I happened upon a comment and answer in the VR4DCS Discord where there was evidently some recent change that DCS could now use three cores / six threads.

So, I set the affinity of DCS.exe for two additional threads.  I went from having to run at 80% custom render scale to 100% with the same settings.  I'd estimate I picked up 10 FPS or so.  If any of you are doing the same thing with Process Lasso, give it a try.  

I'm enjoying DCS with good performance and awesome visuals and no Steam VR.

I do find it wierd that we all have a different'ish experience even with comparable machines.

What i have found is versions of drivers can make a difference, XMP memory settings, whats running in the background e.g. bloody MS defender, NVIDIA drivers (sometimes 5/10% diff), OpenXR companion version etc etc. While i doubt we will come to a concensus on this its great that we (mostly) seem to be going in the right direction with better FPS and better image quality.

[DiAddict]

I tried openxr and the openxr toolkit.  Having a decent performance boost at 100%, but missing the quality boost of having upscaling.

 

The issue is if I use upscaling at anything other then 100% dcs crashes.  Anyone else having this issue?  All other settings in the tool kit work fine, and can be set to default.  Does not matter.  Upscaling can be turned on but left at 100 and DCS runs.  Anything else up/down and again dcs crashes.

 

Any Ideas?

 

Playing DCS Steam Version

Headset is Odyssey +

Windows 10.

Clean DCS Install (Uninstalled and Deleted all relevant folders)

Reinstalled WMR and all relevant OpenXR files programs twice.

[pastranario3]

Well I have realized that: 100% Steamvr is equivalent to 2204x2160 and 100% of OpenXR is 3152x3080 (which would be equivalent to 204% of steamvr). So 100% steamvr (2204x2160) would be 45% openxr (2112x2068). Under this calculation when putting openxr at 100% if there is an improvement because with steamvr at 204% the stuttering is great. Therefore if there is a performance improvement in openxr, now I have another problem is that the rear projection does not work very well in openxr since the propellers of the wwii planes generate artifacts and image displacement in that area, too much that they cannot be use, in the rest of the planes openxr is the way.

Got a simple to follow how to?
