Quest 2 with Virtual Desktop Distortion when Tilting Head

[gamecatuk]

Hi,

 

Everything is working great with IL2. I probably need to slightly adjust for performance but the thing I notice most is a weird distortion when I tilt my head. 

Its fine with any other head movement but tilting to the side causes strange distortion like things are being stretched slightly at that head angle causing the menu to look more like a parallelogram.

Current resolution: 3440 x 1440, 144Hz
Operating system: Win10

 

Any advice welcome! :)

I'm having the same issue, did you find a solution yet?

 

The view gets skewed when head is tilted, like the attached image

I have the Quest and I do get that distortion when tilting my head but only when I start playing with AA settings. I am running MSAA and at x4 it gives me no distortion, I bring it down to x2 and I get the distortion. That distortion is quite apparent when the game loads and you look at the racks on the side walls in the hangar. That's how I also make sure my Anti Aliasing id doing it's job. FXAA or anything less than x4 MSAA the straight lines break up when I tilt my head and the image plane distorts.

 

Try MSAA x4 and see if that solves it. It is more taxing on your system and causes significant drop in frame rates for me, but I find the shimmeirng and distorion on the lower levels unplayable. FXAA does nothing at all to improve AA, MSAA x2 is better but MSAA x4 is best. 

[WoolstonNZMalcNZ]

getting the same effect when tilting head, x4 MSAA made no difference.

 

[WoolstonNZMalcNZ]

i think i have got closer to understanding this. I tried the game last night while hooked up with the link cable - no funny head tilt distortion at all, but when i tried the game wirelessly i got the same head tilt distortion. So perhaps Oculus is having to make some compromise in the back ground to run Virtual desktop/iL2 wirelessly?

[=RS=Funkie]

I also got the skewing effect with Quest 2 running wireless.
Didn't try MSAA x4.
Just went for the Link cable and didn't go back. I don't mind having the cable connected. It allows for other quality improvements like increasing the bitrate and compression resolution.

Otherwise you can risk getting video compression at the horizon which can hide detail.

I have also seen this. However, it only (and always) appeared when using streaming. Using the official Link cable, there wasn't such a sensation iirc. 

 

Addendum: It's an issue within IL-2. You can file a bug report on the IL-2 forums for this. There are testers but I doubt one of them has a Quest2. Best is to just use a cable - you wouldn't want the screens to shut down, out of battery, during flight anyway and the picture quality is better this way too. Make sure to buy the original cable.

Why do you suggest the original cable? I have a $15 dollar cable, others I know do and many posts on the Oculus subreddit recommend aftermarket cables.

I have seen and heard of no issues although I'm sure some cables could be of lesser quality. I just followed the recommendations on the subreddit and crossed that reference by reading reviews on amazon.

 

Edit:here is an Anker aftermarket cable for $22 approved by Oculus https://www.androidcentral.com/best-link-cable-alternative-oculus-quest-2?amp

[SCG_Fenris_Wolf]

Hi,

been told Oculus refused support if it was not the original (or then an approved cable) if any issues arise. And that not all cables have the same throughput - they may work at the first glance but some throttle. Correct me if I'm wrong, as I was quoting what I had been told.

Highly suspective of bad and dishonest services these days. It's great if that cable delivers the same throughput as the original one and is recommended

Currently getting better performance on VD in terms of aliasing atm with my Q2, but running into the exact same problem as other posters here. Any idea how to fix the warping, or are we stuck with link?

[Spasticus]

I have the same issue in wireless. It's still quite playable but a bit annoying. 

[IRRE_Belmont]

Same issue here, a shame because the image is so much better when using VD.

[IRRE_Belmont]

A few things about this issue :

- Testing out different anti-alliasing didn't help, some user reported that was the problem on their end and that using MSAA x4 would solve it but no such luck here.

 

- This only happens when using Virtual Desktop, using Link/Airlink gets rid of that problem, however this is not a good compromise as the picture quality takes a huge step back.

 

- Everything looks ''fine'' on my computer screen, which makes me think this is indeed a issue with the Quest 2 not being fully recognized while using VD.

 

 

[SCG_Fenris_Wolf]

Guys, Airlink is out. Can you check whether the picture is correct there please?

Wait, you're getting better image quality through VD than the link cable?

 

That could be because you're using a third party link cable, or a slow USB port.

The bandwidth of a good cable through a good usb port should trump what VD can provide.

You can do a USB test in the Oculus software, see what speed you're getting through the cable. Mine is 2.4mbps or something like that. For a third party active USB cable.

Then, if you want more quality with the link cable you can do two things.

Well, firstly, make sure you're using Open Composite, as it bypasses Steam VR and gives you a better frame rate.

And secondly, you can run OculusTrayTool.
Set your default super sampling to something like 1.3
Then go to the quest link settings and give yourself an Encode resolution of 3648 and bitrate of 350.

Thirdly, make sure that in your oculus software > Graphics preferences, you're set to 90hz. And a higher rendering resolution like 1.2.

Depending on your PC hardware, these settings should run ok. But they are demanding, so you can just change all the settings back if its not working well.

Doesn't help, @=RS=Funkie, I also let them know earlier, to get the original, but was countered with "I have a $15 cable which is recommended and fine".

Picture works fine on airlink, it's only wonky on VD.

I own a proper link cable, VD sometimes still looks better than link or airlink. There's a lot more going on than just bandwidth.

Nope that's not it, VD uses custom resolutions depending on the quality you desire and also uses a different encoding than link, the image is way crisper than link, the official cable, on a USB 3.0.

Sure, let me pay 90 euros for a fooking USB 3.0 cable, when Oculus themselves have been saying it's ok to use other cables, as long as their speed is similar.

VD's performance has always been impressive, 1 man dev team getting better results than Oculus.

 

It's particularly relevant for IL-2, as I swear on testing it on VD it resulted in less aliasing shimmer than with link, albeit with the distortion problem which I reeeeally hope gets addressed soon.

 

As for the cable, I managed to get it for £50 instead of £90 and it's still given me more problems than my £12 amazonbasics cable. Had to return the first one and now the 2nd is starting to get iffy.

Personal opinion: Now that AirLink works properly, I don't think that this may see a fix to be honest. It's a 3rd party software after all. Devs are working their butts off to code on and improve new features of the game, I wonder if they see this or got time for it. When I tried VD, the Oculus Link cable was much better than VD, which produced quite a few artifacts. I know you disagree, but that was my observation. The fact that VD allowed for just a short time of flying (barely one mission of TAW) was disenchanting too. But this is just my personal view.

But: If it gets fixed, all the better!

Yeah i'm not holding out for a fix. Apparantly it works fine with Q1 so I wonder if it's trying to run on Q1's specs when you use the Q2. Might explain the odd distortion.

 

Performance with VD will differ drastically depending on your particular WiFi network setup and settings, and you can still use it while wired or hooked up to a battery bank. It also has the advantage of running in 120hz now as well.

 

I'm lucky enough to have a decent extra router lying around, and already run my internet via ethernet, so it's perfect for me. That being said, even air link feels better than link now imo. I do wonder what they have screwed up on the wired link for this to be a fairly common opinion.

Can this get fixed please? 

[=STP=Darrylx444]

I have this same exact tilt-warp problem on my new Vive Pro 2. It also looks slightly compressed in the vertical axis for some reason.

 

This only happens in IL-2, not on DCS.

And never on my old Pimax.

 

Edit, clarity: Also, I'm not using wireless in any form.

Will hijack this topic but did you guys do anything to get Il2 to work with virtual desktop? I was getting head movement multipliers and incorrect height / width ratio of the image so ended refunding the app and using the regular link / airlink.

It is 45 fps / 102 FOV as reported in-game. Do you have the same problem on a VP2?

 

[BH_Adabadoo_VR]

air link does work but it's not as sharp as virtual desktop and not as nice to use...

Yes. Thank you, I have forwarded it to the Devs 2 weeks ago. I forgot to reply to confirm to you here.

Hi,

 

I have only ever played Il2 via wifi  on Virtual Desktop and this has always been a problem for me but I have today, by accident, found a fix on my quest 2.

 

I have found that if I start VR with the pupiliary distance at the max position (68mm) which is correct for me the effect is very noticeable, however, if the headset starts up in the medium setting the effect is not visible and does not come back if I push it out to max PD.   If I take the headset off with max PD set and it goes to sleep then put it on again, the probelm is back and is not fixed by putting the PD to medium. I need to close VR, put it on medium PD and start VR again.

 

I don't know why this should work, but it does.   Today was a good day to fly.
