Vive Pro 2: Warping Issue, only IL2

[SCG_Redcloud111]

Hello Developers

 

I received my HTC Vive Pro2 and have been testing it. With all games, it works as expected. In IL2, though, when I roll my head along the X axis, warping occurs. I am guessing this has to do with something related to its optics and how IL2 interprets them. I had the Pimax5k+, and I remember you guys had to do something so that we could fly without parallel projection, as well as do something to fix the zoom. Anyway, if someone could look into this, I am willing to test it for you.

 

Let me know. Thanks.

 

Keep up the great work!

What is the X axis for you?

 

[SCG_Redcloud111]

What I mean is that when I roll my head left or right. For example, while wearing the headset, when I move my left ear toward my shoulder and vice versa. 

[chiliwili69]

OK, thanks. This is then the vertical axis (usually the Z axis I think).

 

I just notice a very subtle distorsion when moving the head from left to right but I was more concentrated in checking other items of the headset. I will take a closer look.

 

I assume you update the latest firmware and latest GPU drivers, etc.

I think this is the issue Fenris documented here, amongst other mentions in the Vive Pro 2 threads:

IL-2 looks great as well - until you tilt your head. Yes, similar to the Virtual Desktop issue, the geometry in IL-2 shifts like a tilted rhombus. The headset's geometry must be added to IL-2 first, like other headsets before. I cannot say more, but I am certain the Devs are on it. You can be certain that the Devs are on it. But until that has actually been done and tested, IL-2 remains not compatible to the Vive Pro 2 in my book, we must be clear and honest here. I am positive however, the Devs fixed it quickly with the WMR headsets as well. They always want their Sim to be top notch.

Yes it is already reported and the Devs have all the data to fix it. Now we just need to wait

Aren't they going on vacation soon as stated in the last developer diary?

Hope its fixed before that and not at the end of the summer.

[SCG_Redcloud111]

Yeah, I saw that. I hope it gets addressed soon as well. No flying for me until they do.

I have seen now this warping issue. It is as you say when rolling the head along X axis. It is not too extreme but noticeable. 

I thought it was when turning left or right (yaw movement).

for me the whole picture looks stretched horizontally, like if trying to play a 4:3 movie on a 16:9 screen in full screen/stretched mode.

[=STP=Darrylx444]

Yes, this is confirmed on my Vive Pro 2 also. Parallelogram warping when tilting left / right ear down, AND a slightly squashed perspective overall (circle looks like an oval). Only in IL-2. I can live with it for now but will be happy when the devs fix it.

[Arrowhead]

Argh, I can't live with it. When are these guys back from vacation and going to fix this? Maybe I will uninstall this for the summer?

[SCG_Fenris_Wolf]

It should not take too long...  ..I hoped. We couldn't properly fly IL-2 for weeks now. Missing IL-2...

I'm looking forward to testing my Vive Pro 2 in IL-2 when the patch is out. For now, it looks like I'll have to keep setting up my Index any time I want to play.

[SCG_Fenris_Wolf]

There's no update yet. Really bummed out about this... 

 

5 weeks and counting.

[Guest deleted@134347]

I looked in Bugs section and didn't see anyone actually reporting this issue.

 

So I opened a thread there as well:

 

 

 

[Arrowhead]

War Thunder is the only other game I've found to have this same problem. Doesn't that engine share the same sort of roots as IL2?

[SCG_Redcloud111]

Hey, devs, just wanted to touch base regarding this issue with the Vive Pro 2. I originally posted it at the beginning of summer. I figured things slow down in summer, so I was expecting to wait a bit. I haven't done any flying in Il2 since I bought the VP2 because of this warping when tilting. No other flight sim I use has this problem (i.e., MSFS 2020 and DCS). I thought I would ask if there's any chance for some movement on this fix? I would be willing to do any testing, if that would help (although I am not a software engineer). 

 

Anyway, keep up the great work on the best WW2 combat simulator we have. Take care.

 

@Jason_Williams @Han

[SCG_motoadve]

This needs to be addressed please, VP2 works good in other simulators, we have been waiting patiently but its  months now.

[=STP=Darrylx444]

While I was grateful for the dev's acknowledgement of the issue last month, I was still quite disappointed that nothing happened in the latest patch.

We all know the correct rendered FOV aspect ratio of this model already from SteamVR, as retrieved by Risa's tool. I'm no expert, but how much time should it take to just implement it?

[=STP=Darrylx444]

Ugh. 4 months have passed now. Jason was right about it taking a long time, I guess. I wonder when the next patch is coming, and if it will bring any movement on this issue.

[SCG_Redcloud111]

I think they need an VP2 for it to get fixed.

In stock on Amazon. It takes one week to order and receive one. They've been available for 4 months so far.

[SCG_Redcloud111]

It might be an issue of paying for it ...

[SakerVVS]

I have almost everything but I will not buy anything else, much less even play until they fix the VP 2 issues.

 

[Jason_Williams]

Guys,

 

Were aware of the issue. We just now after 18 months got access to our VR machine again in our actual office. Nothing is easy to acquire or do in Russia these days. Ever send a FedEx or UPS package to Russia? It don't work. Trust me I have tried many times. Even domestic purchases have become hard. We've been handicapped during the entire COVID era. Hopefully we can get this issue sorted, but until my Lead Programmer has a unit in the office we don't know what's up.

Any insights on this for these guys?

Thanks for the follow-up Jason. Dang, that's a pain in the butt. When did you order it?

 

Separately, have you considered the option I mentioned 3 months ago that might avoid the need to buy one by using the SteamVR rendered aspect ratio values retrieved by Risa's Tool? I'm sure several of us would be happy to install a private test version / closed beta / whatever. Whatever we can do to help, please let us know.

 

[SCG_Redcloud111]

Thanks for the update. I understand the difficulties. Get to it when you can. No worries. 

[OrLoK]

Just fyi, its not just you Vive Guys, im having this as well with my Quest 2 via Virtual Desktop (cable is currently being fixed by Oculus).

 

Its a pain but not game breaking, look forward to a fix whenever it can be achieved!

 

edit: either I missed an update or my issue's suddenly resolved itself

Let's correct the record. It is just us Vive Pro 2 guys. Your problem was obviously unrelated as the skewing persists on the VP2 now and is not suddenly resolved.

 

War Thunder had this exact same skewing with the VP2 and they have since resolved it last month. My understanding is that War Thunder shares its roots with IL2. Maybe IL2 devs can talk to Gaijin for their values and implementation for the VP2? Or contact HTC directly. If they can send out free Vive Pro 2 samples to mediocre Youtube influencers, surely they can help out a big time dev behind IL2!

[OrLoK]

whilst i feel for your issues, I *did* correct the record, its the bit in bold  

[SCG_Fenris_Wolf]

You're both looking in the right direction, both aren't entirely correct though. 

 

@Arrowhead They don't send out headsets for free. It's not HTC's "fault", so to speak. You can set up any headset properly without buying it, the issue is within the legacy engine of IL-2 itself. IL-2 is the only title with this issue, so let's call it an IL-2 bug, without diving too deep into the libraries.

 

@OrLoK The issue with the Q2 was similar, that it wasn't properly recognized by IL-2, so let's call it a bug as well.

 

Let's hope they can fix it soon and we'll all be happy. I've put enough money into IL-2 over the years and bought stuff for other players too. I alone covered the price of a VP2 and more, and I don't like to play that card but it's about time this gets fixed by the IL-2 Devs.

 

Make no mistake, I will open a fine bottle when they do, and still celebrate. It's still my favourite (unplayable) game.

I saw a report over on the DCS forums that today's Vive Console Beta update fixes the Motion Compensation issues with the Vive Pro 2.

Will probably be a few days before I can try it in my flight sims.

Just tried it with the new Vive Console  beta and Motion Compensation still show artifacts in IL2 (I might be wrong, but I though that this has to be fixed by the game developers for each game and not the Vive software? )

Nah I think that is a Vive thing. Sounds like it is not quite there yet, thanks for checking.

Edit: Oddly enough I have now seen two reports over on DCS forums stating it made a big difference for them.

 

Edited October 26, 2021 by dburne

[SCG_Fenris_Wolf]

Yeah that's two factors playing together.

 

Vive thing with being unstable when FPS fluctuates (jumping between 90 and 45, or 120 and 60, it needs to continously sit below 90 or below 120 respectively because it breaks whenever it dips into high FPS again). And IL-2 anyway as well because it doesn't put the depth information forward to the OpenVR API. You can easily check this in IL-2 with sunrays, the propeller (the solution is just a workaround), or when you look at the wings while taking off.

 

 

So whatever you do, you cannot test it in IL-2. If you want to test that Motion Compensation works properly you must use it in another game, like DCS, or MSFS2020, or HLA. For the time. Whenever IL-2 Developers start updating their engine to Dx12 & forward shade rendering & OpenXR , which is the natural course (F deferred shade rendering for it is a dead end regarding VR), then we may see better performance there.

I saw the update today, but haven't tried it yet in either sim. Will give it a go this afternoon, probably.

 

With the openvr_fsr mod, I can already maintain 90fps about 90% of the time at 90 Hz, so I don't get the mandatory half-fps + ghosting thing too much (MC disabled). Still happens a bit in a fur-ball, and continuously in tanks.

If Vive's "new and improved" MC mode actually works well in both sims, then maybe I can try 120 Hz mode again and get 60 fps 100% of the time, with minimal artifacts. Here's to hoping, anyway.

[=STP=Darrylx444]

Update to my last comment: Having tried it just now, Vive's updated Motion Compensation didn't impress me at all in either DCS or IL-2. Still much better to just leave it off, even if you can't maintain full Hz fps. Not so much because of artifacts (still there), but mainly the overall "jerkiness" was terrible, IMO. Only tried at 120 Hz (Ultra), which rendered 60fps 90% of the time in DCS, and 120fps 90% of the time in IL-2. Single-player tested only.

Jerkiness is worse now than the last beta in IL2.

Also tested the latest Vive console beta in MSFS 2020 and it is smooth as glass, no artifacts or nothing.

Why it does not work like that in IL2??
