Vive Pro 2: Vertical Diplopia

I've scoured the internet and can't seem to find anyone else having the same issues I'm having.  There was a hint of something similar in the DCS forums, but it seemed more isolated to that environment.   The issue I'm having is vertical diplopia, no I don't look like Sloth.

 

The effect is just the same, its as though I need a vertical IPD setting to solve.   It only happens in IL2, every other title (DCS, Elite, Automobilista, VR VOTL, Ironwolf, etc.) things behave exactly as expected.

 

I upgrade from the OG Vive, and aside from poor resolution and screen door effect, I've never had an issue with it.   

 

Since moving to the Vive Pro 2, I've reinstalled drivers, reinstalled IL2, reinstalled Windows, all to no avail. 

 

Other oddities I've noticed:

 * With just the headset upgrade, tracking isn't as good as it was with the OG Vive.   I'm not sure if its a issue with my hardware, but I had to adjust the throw on the lighthouses, and move to another part of my desk to have no break in tracking, where on the OG it was never an issue.  I have the lighthouses laterally and to my back.  Not ideal, but never had an issue before.

 * When I go to adjust the IPD  in the headset, while in IL2, the IPD interface experiences the same issue.  Very noticable this way as the text is stacked.

 * using the in-game IPD adjustment has no noticeable effect.

 * stepping through in-game graphics settings has no effect.  (Presets and individual settings)  I've tried min and max and numerous other settings.  

 * There is are a number of OR (VR) related settings in startup.cfg.  None of these have noticable changes to the vertical offset. (I had big hopes the or_ipd or or_sipd were going to be wins, but no joy.)

 * I was unable to force change resolutions, IL2 seems to read it from Vive Connect or SteamVR, any change I made was over-written on load).

* Similarly changing various setting in SteamVR or Vive Connect as it relates to graphics, had zero impact.

*All three DPs on the GPU have been tested.  All variations of single monitor and headset have been tested as well.

*All USB ports have been tested.

*Installed Nvidia Studio Driver vs Game-Ready, no change.

 

I did notice that prior to the menu loading in IL2 the hardware IPD adjustment looks normal but as soon as the menu loads, everything goes to hell.  

 

 

Last thing, with the issue present, the menu text is crisp and un-erred.  There isn't any doubling of the text or other blurriness in the menus or briefing screens; however, all the 3D rendered elements, plane, pillars, workbenches all suffer from the same vertical duplicity.

 

I'm at a loss.   I decided to hang up VR previously because my declining eyesight and the resolution on the OG Vive.  This this has been perfect in everything but IL2, and IL2 is really what I wanted to experience the most.  

 

IL2's Steam VR video settings behave differently than most other titles, changes to game-specific settings in Steam VR (World Scale and FOV) take effect immediately.   Most titles don't do this, but I found a couple that did, and this exact problem didn't surface.   Actually its almost as if the FOV is off by a little in game.

 

Any ideas or suggestions of other tests to try are very welcome.

 

Thanks,

Make sure you don't have any Direct3D injectors like Reshade or similar installed.

Appreciate the suggestion, it is a good one, and I do use reShade, but not with IL2, and I've done a full reinstallation of Windows 10, and full delete of my previous iteration of IL2, with minimum installation of other software.   I've also disabled any tool or application that provides an overlay.  Its almost as though IL2 is rendering two different FOV, one for text on the menu and briefing window planes, and one for the game engine.  It's just that everything outside of the menus and briefing is showing this vertical offset.   I noticed that the pitool software has a vertical offset for this very type of thing, I wish there were something like that for the Vive, but I think I'm the only one having this issue.

 

The best way I can describe it is,  it's as if you have max VR zoom enabled.  Have you ever noticed when your at max zoom things get doubled, its like that but on the vertical.

Thanks for the suggestion.

Is this also visible on the game's and SteamVR's desktop mirror?

 

There used to be an issue with IL2 and wrong aspect ratio with the VP2 but that resulted in a distorted picture IIRC.

That's what it kinda feels like.   Oddly enough, picking up a controller and tabbing out to Steam's VR console, and looking at the desktop mirror, it will clear up.   It seems like its transitioning while I sit, but that's likely just my eye's restoring back to normal focal points.   I notice after trying to fly a quick mission, my eyes do the same when exiting to desktop (uncrossing themselves) is what I'm guessing.   Its just weird, because I would expect to see it on the horizontal, but this is all vertical that I see.  

Over the weekend I did roll back to an older version of the Vive Pro 2 console for Steam VR.  This at a glance appeared to fix the issue in game, though the hardware IPD adjustment still appears as double.   I've not been able to go back and test, as the fatigue is just too great.   I'm going to try again after work this afternoon, when I've more time available to sit and test.

Couple of other things to check in SteamVR's settings:

 

1.  advanced supersample filtering is disabled

2. and the custom FOV slider is set to 100%

 

Both of those can be set in per-application settings and both have been known to have varying issues on some headsets.

Ha! Yes, my friend, I'm a little OCD.  I'm pretty sure I've toggled nearly every combination of settings.  I just reinstalled Windows and IL2, nothing else, save vive console, and steam VR, the issue still presents.  I can't think of any other option to tweak.  Its just IL2 that causes this.   I did notice if I look down the bridge of my nose (like looking at your feet without moving your head) everything comes into focus and looks as it should.  At this point, I think I'm going to give up on the hope of success with this headset, and return it.  At $499 it had a lot going with it, but I was disheartened that it needed another layer to talk to SteamVR, and then these issues with IL2.    Shudder to think, but maybe I should just go with the Meta Quest 3, that will at least be something unthethered that I could share with the wife.  Looks like the PiMax Crystal Light uses lighthouses, so maybe that's the better option, I didn't like the inside-out tracking of the WMR headsets, made me nauseous from the delay.

 

Thanks for the suggestions, really appreciate it.

Vive Pro 2 user here. Yesterday I fired up IL2 for the first time in months (DCS being my go to) and experienced the exact same issues as OP. Will stay posted and share any progress.

[rekim]

This week there were software updates for my GPU (Nvidia), SteamVR and 2 updates to the VIVE Console. Following the updates I tried IL2 and found that the cross-eyed effect was almost completely gone. The main screen seemed fine, as well as in flight. There were a few moments where I felt that the vertical diplopia effect, however, they did not last.

 

I tested IL2 only briefly after applying the updates. Will give it a good run through a bit later.

[Rujo]

Damn, I just missed your post a little too late.   Please do let me know.  I ended up returning the Vive 2, but they are still on sale.  Everything else worked fine for me, save for IL2, but that was enough for me to send it back.   It was the lack of anyone else seemingly running into this that made me return the set, everything else I was happy with.   It's hard going back to the OG Vive after seeing the clarity of the VP2.   I only had two weeks to test and return, but I do miss it already.  My testing with IL2 was giving me headaches, and affected my vision for 2-3 minutes after I would take the headset off.   

 

Thanks again,

Just bumping this issue because I have the exact same problem with my Vive pro 2. 

Very disappointing as this game was a primary interest in getting a VR set. My left view seems SIGNIFICANTLY higher than my right. 
My drivers are up to date, my game is up to date, i never used any other VR setups, my SteamVR is up to date, my Vive console is up to date. 


I do not know where else to go with this as i can't seem to find anything.

I have exactly this problem using a brand new Bigscreen Beyond 2 headset.

I've been playing IL2 in VR with no issues using my Quest 3, but I can't get it to work at all with the BSB2. As describe here, it's like there's a vertical offset difference between the two eye positions with this headset.

 

I think it must be some kind of issue with the way that IL2 is mapping the eye-view rendered images to the actual headset screens because the view I can see on my 2D screen showing both eyes side-by-side looks to be correct. It's only when this gets mapped to the headset that the problem seems to occur.

 

Do the devs look at these forums at all?

This could be a quality issue with the BSB2 hardware. I would contact BSB2 support team.

I had in the past the VivePro2 and there were no issues.
