Finally! Quest2 no more shaky head

[Fuggzy]

Earlier today I read here that DCS supports OpenXR natively, and it's easy enough to try, so I did. No changes to start checklist... I always run an OTT profile to get a tiny desktop resolution in DCS (free fps and hell if I know why) and ASW.

It ran awesome on launch, maybe faster I dunno. But in fumbling through the OpenXR menu I saw Shakiness Reduction...   tried -40% ... oh my.  Cranked it to -100% and thought I was going to pass out.  THIS is what I've wanted, a helmet display that doesn't track every single muscle fiber twitch in my toe. Just smooth and precise without me having to strain to stay still, like a TrackIR does it. Because the IHAADS is so prominent and necessary in the Apache, I'd all but given up flying it in VR because of the extremely annoying shake on it.  Fixed with OpenXR! Now I can put the reticle right where I want it and hold it. 

Even better, this makes VR zoom usable! Before, it was so dang shaky when in zoom that it totally defeated the purpose. Imagine using binoculars while shivering...you'll see nothing. Now, I zoom in and the picture is nice and stable.  Very happy that I gave OpenXR a whirl, just for that alone.   Thank you to ED for adding support for it.

i found that with -100% i get a faint vertical black shade when moving the head rather swiftly from right to left, and it disappeared at around -40%. Although in some jets i am not using it (i think every adjustment will have to be computed somehow, so... cpu frametime), but in some crafts, maybe Apache included, the shaking is more profound than in others. 

 

but... i didn't know zoom works in VR... i have zoom key bound to the slider on my hotas and it never did anything... how do you use zoom in your VR setup?

There is a "VR zoom" option in the UI Layer section of the controls.

thanks! i will check that out.

Does this make targeting AIM-9X with the JHMCS better? I've never used VR zoom (I don't think I'd be using binoculars in the middle of ACM), and can read the displays without noticing any jitter, but targeting with the JHMCS is a real pain because tiny head movements move the reticle around so much.

I don't want to feel like the view is slower than my head movements, but if it makes targeting feel more natural, that's definitely something I would want to try!

I can confirm it makes AIM-9x HMCS targeting in zoom mode not only usable, but fricken sweet too. That is the 1st thing I set out to test in the Viper.  Can do now.

What OpenXR menu?

The in-VR-session menu -- once you're in DCS, hit R-CNTRL+F2 and it should raise the OpenXR menu.

That has no in-game menu.
DCS default mapping is Object Free Camera view

Is this a Quest2 only feature?

 Hi @MHAce75 I think I know what you're talking about, if that vertical shade you see is on the sides - specifically the side you're turning quickly towards? The effect is like the scene isn't quite keeping up laterally, even though fps and performance is fine.

In OTT I had set FOV at .8/.8 for a long time for the performance bump, but I discovered that by putting it back to 1.0 it got rid of that noise.  My hypothesis is it's still there, but it's now beyond my view. It's still subject to overall performance, and whenever frames take a dive for whatever reason, the shade comes back.

Right Control + F2 is the default. If it's not coming up when you're in VR at the DCS main menu, it might still be running Oculus api and not OpenXR.

Running a ReverbG2/WMR, might be why it's not working.

that's it. i tried with -100% again, it is quite pronounced, all down to -50% i have that faintly still, at -40% its ok, and that is where i have settled now.

While DCS is now running OpenXR natively, I'm pretty sure you'll still need to install OpenXR Toolkit to access the settings referenced above... Specifically the "OpenXR Companion App" - That's what the R-CTRL+F2 opens (It can be remapped)

I'm also running a reverb G2 & WMR and I can confirm that the tweaks in the toolkit can make a world of difference.

I am curious, do you shake in reality or something?  Because I personally do a fair bit but never noticed the quest 2 being more shakey than I myself actually am.  Or is it a DCS specific problem, I never used the quest with DCS.  If you do shake, does removing the shaking in the headset not "feel wierd"?

i think the problem is that the software interprets tiny/minute movements as in one or the other directions, resulting in a shaking simulation, making it difficult to focus on cockpit instruments. in reality eyes and brain will compensate shaking and the picture we see will remain stable. 

I found the cockpit shaking is more profound for some aircraft. I recently installed an additional module - i believe it was the Huey helicopter - where the cockpit shook unbearably and also unrealistically, so the shaking reduction to -40% helped with it a lot

Total newbie here with a Quest 2.... are we talking Open XR toolkit? I cannot get a negative value on the sharpness??
