OpenXR Guide - Deprecated - This time for real (▀̿Ĺ̯▀̿ ̿)

How do I get the quest 2 to open DCS Open Beta and use the openXR tool kit? Whenever I try it just launches through the oculus software. I have installed the openXR tools through windows, open composit and switched it and also downloaded the openXR toolkit. The closest I can get is running the demo in openXR tools but the toolkit will not appear and DCS still opens in Oculus.

This isn't entirely correct. Turbo Mode will interfere with Motion reprojection, but it is being discussed as "turn it off" anyway in the conversation.

Turbo Mode heavily relies on Spatial reprojection (something that is always on), it makes it work a little harder due to extra latency, but it's an essential part of the process. Without it, Turbo Mode would create a wobbly mess.

Regarding WMR Motion reprojection, some significant improvements are currently in testing before release, and my tester with DCS claimed "it looks significantly better for me [on a 3080Ti]".

Thank you very much friend, glad to hear from you. For me personally, Turbo mode suits me better, I tried removing it but what @speed-of-heat says, happens to me.

with turbo mode off, it just looks like i have blurry/double vision when i look out the side but it is "smooth" blurry/double vision...

Using the WMR portal resolution at 60Hz, are you also using the OXR frame rate lock at 60?

when i am using 60hz, i am not locking the frame rate, there doesnt seem to be much point, i am using turbo mode with 60hz. 

[Nahemoth]

Just a silly question... what is the turbo mode?

[Silver_]

It's a mode that is activated within the OpenXR toolkit, my friend.

[freehand]

I would rather cut my left testicle off than run in 60hz in vr.

What is the function of such mode?

Thanks!

Run DCS.exe with additional parameter --force_steam_VR

Turbo Mode disables all v-sync (frame wait needed to reduce latency) and this means letting the game completely max out your GPU by just going as fast as possible without trying to reduce latency. Because the platform does a good job at late-stage reprojection (compensating the images for head movements), the extra latency is not that important, and the gain in framerate is well worth it.

Your mileage may vary however: Turbo Mode can have as high as 20 FPS increase in some situations, but can also not give much in others.

As with all things if it works for you awesome, for me locking frame rate leaves the whole thing a blurry juddering mess, (out the front its fine) out the sides its horrible.  My current approach which is achievable is to use 60hz (shock horror... which i trained myself not to hate ) and neither use reprojection or frame rate locking .

It is strange. Thanks to your advice I got frame rate locking working but there is no value that works as well for as motion reprojection for smoothness if the frame rate is below 90 (or 60).

I also get the blurry juddering effect be it locked at 45,46...55 fps

I haven't been able to cope with 60Hz, maybe I need to try longer.

the "tricks" that worked for me 

1) is little steps, slowly increasing the time each time around to slowly build tolerance, it took about a month for me to get to "not noticing" 

2) lowering the gamma and or using the sunglasses setting in OXRT

3) ... and this is the tough one staying away from 90hz while you are acclimatising (it seems to roll back any tolerance you get) , once you have tolerance slipping between the two is easy 

I did 3 x 90 minute missions yesterday with neary a worry ...

I tried downgrading a couple of times and mostly can't take the flourescent light flickering effect I see on light areas in the corner of my eyes, like the clear sky. Does that effect diminish over time?

certainly my awareness of it did, i assume its still there, as i said reducing the gamma was a big first step there ...

I just tried it again, using the sunglasses OXRT option and the fluorescent light flickering effect really does diminish as I moved between options.

I think reducing the brightness may be key, so sound advice. It certainly is nice to be at refresh rate. On to try some more!

[slughead]

I mentioned a while ago that it's the bright parts of the image that flicker the most or is perceived to flicker the most. Reducing the "highlight" option in the toolkit companion app will help by only adjusting the bright parts of the picture rather than the whole image..

My PC (8600K & 2080Ti) is on the cusp for maintaining 60fps at the best of times. Hop in the Apache and no chance!

What I would really want for is for motion reprojection to cut in if it drops below refresh rate. My understanding is that this can't be done with OpenXr - is that correct?

Not sure what "cut in" means, but today this is how MR works: it only engages if you cannot hit refresh rate.

I think what he’s asking is does or can OpenXR MR actively engage when the frame rate momentarily drops below the threshold (say in an area where there’s a lot of objects or activity) but then DISENGAGE when the system is able to maintain the threshold again?

SteamVR motion smoothing does this - I can fly around at 90 fps most of the time but say I fly though smoke or a busy area it’ll turn on smooth things out then disengage when things calm down (ie Auto).  My understanding was the OpenXR MR can’t or doesn’t do this… it’s either always on or always off. There is an “Auto” setting but it supposedly doesn’t do anything.  Is that right?

My options are always on, auto or disabled. Auto is what I want but my understanding was this didn't work with DCS. Is that wrong?

[edmuss]

You want to set it to always on and leave it unlocked in openxr toolkit. You'll need to beat refresh+reprojection overhearld (1-2ms) if I recall correctly to keep it disengaged. Basically it'll likely need to be around 14.5ms appGPU to breast the 60hz refresh.

[Tusk.V]

I've found the best results with the following:

• Render resolution at 130% in OXT (I tried 150% but I would occasionally drop from 45fps to 30fps. Still wasn't bad but I'd prefer to stay at 45.) 
• Reprojection turned on (I fly the Hornet and it is smooth as butter)
• FSR at 75% with 0% Sharpness
• FFR at Quality, Wide
• Cockpit sharpening and haze reduction through 3dmigoto

My frames stay locked at 45fps in all free flights. This might not be the best way, but it works for me. I might end up turning off FSR and see where that gets me.

Eureka! this worked... I was completely unaware of the "Unlocked" option in the OXR toolkit.  I've been looking for the ability to have MR "on-demand" i.e. only come on when I dip below 90fps and basically be off otherwise.  I've got a beefy machine and play with very starkly configured visual settings in the hopes of maintaining 90FPS as much as possible as I just can't look past the artifacts that MR creates (especially the rotors in the AH-64D)... so having MR on only when it absolutely has to is great.

Thanks for posting this!

Auto is misleading and it only means enabled in FS2020.

For other games you want to use Always on, which is a misnomer, Always on means Always on standby, and it only engages when you cannot hit the refresh rate 90 or 60 based on your WMR settings.

So for short: use Always on, because it does exactly what you described you want it to do.

Always on does what you want (only engaged when needed based on frame rate). This is the same exact behavior as OpenXR Toolkit Unlocked mentioned in your other comment.

Having something called Auto was a huge mistake we made and I am going to remove it ASAP due to all the confusion in creates.

Interesting - did this "on-demand" capability of OXR/WMR motion reprojection change at some point?  I seem to recall months and months back (I took an extended break from DCS a while back) that I couldn't get MR in WMR to do this - it was always on (even in bland scenarios where I could easily maintain 90FPS).  Just curious but either way I see that it does indeed do this now so that's awesome thanks for the explanation!
