Resolved(ish)…Oculus 3 Left eye issues

[SY_KO]

2 days ago I was in VR and tuning for optimal FPS.  Started DCS up with same settings but now the left eye doesn't load... ish.

 

On the initial loading screen both work normally but when i get in to the initial game menu the left eye is a dark grey (screen is on but nothing rendered).  I launched an instant action free flight and its the same left eye issue except:

- The launch mission menu

- I can see unit name tags (blue and red)

- the OXR fps counter overlay. 

Right eye appears normal rendering in the cockpit, landscape, aircraft etc the left eye doesn't.

Any ideas?

 

*tried repairing DCS... no joy

I see you have the Virtual Desktop API layer extension in your log but you are using the Meta link app. Does this same problem happen in Virtual Desktop? Are you connected via cable or using Airlink? Do you use the Oculus Tray Tool or Oculus Debug Tool? Drop screenshots of the settings for those, as well as the Meta app, in here as well.

I dropped your log file into the DCS log analyser which had the following to say:

• Enable Full Screen mode.
• Set Preload Radius to max. 60000.
• Disable civil traffic.
• Consider using TAA instead of MSAA.

Also as you only have 32gb of RAM you should add a custom page file. At a custom page file with Initial and Max values of 32768 and click Set, Apply, and restart your PC. Make sure that the page file is on your fastest SSD and that you remove any other page files, e.g. the log indicates you have a standard Windows system managed one.

Thanks for looking into this.

I use the Meta Quest link via a cable with the Oculus Tray Tool and was getting 75fps a couple of days ago without issue on the F16 free flight instant mission.

I made the adjustments per the analyser but no joy.

I have 64gb arriving tomorrow.

Hi, so I tried a couple of other things:

- rolled back AMD drivers - no joy, still no left eye

- Tried virtual desktop instead of Quest link - no joy, still no left eye

The issue only happens with DCS.  All other games and Apps work fine with both left and right eyes working normally.

 

Any ideas?

If your using open xr toolkit  have you made any changes to the Field of View setting. That setting worked fine for Virtual Desktop on my system but messed up if I tried to use oculus link one side was out of focus for me. Set it back to default 100 and everything was back to normal.

We made progress!

I changed it to 1.0 FOV and the left eye came back!  I quit the game and tried tried changing back to 0.8 and I noticed a notification in Meta Quest link that OpenXR was not enabled by default so I enabled it and relaunched DCS... the issue returned.  So I went back to 1.0 FOV.... issue remained. I turned off OpenXR selectively in the OpenXR toolkit for DCS and the issue went away.  Turned OpenXR back on and the left eye returned.  I played with the turbo mode and max FR settings in OpenXR in VR, restarted DCS and all is OK still.

So in summary... it was something to do with openXR, no idea what exactly but both eyes appear to work again

About the only thing really use open xr toolkit for anymore is adjusting the colors and the sunglasses option. Helps with seeing the hud in bright backgrounds.
