While I have you here, is it possible to use the QVFR tool only for turbo mode? I've heard you can disable it for certain programs using the config file, but this doesn't work for DCS. It's that still the case?

I replied in the other thread.

To answer your question @mbucchia, the eye tracking check box doesn't seem to do anything. I have a Quest Pro, and eye tracking stays enabled whether this box is checked or not (as long as it's enabled in the headset and link software). I tested it using the debug feature, and just by looking at the sun in game. It's very easy to tell when eye tracking is enabled.

 

The other box for QVFR must be checked in order for your software to work. Without this checked, it's the same as if QVFR is not installed. I hope this is helpful info for your edits to the wiki.

Thanks!

Why are we wanting to use turbo mode all of the time? What is it doing that helps so much? Is it hardware dependent. I have top grade system 9800x3d,4090, 64g, ssd, etc and find turbo mode causes me stutters.

Update to my earlier comment: The Quad Views Companion app v1.0.14 added support for configuring the height and width of the focal area for fixed foveated rendering (non-eye tracked headsets) a few days ago.

https://github.com/TallyMouse/QuadViewsCompanion/releases

Can you post a pic of your config file so I can see what was added to the QV companion? 

I am running a G2 right now and added my own lined for the fixed regions.

I'll be getting a crystal light tomorrow, god willing UPS doesn't mess things up.

Attached is my config, I added the lines 6-9, which weren't present when I installed QV a few months ago. I also dont remember seeing them in the companion app.

For me, I get microstutters when I don't have turbo mode enabled. This is basically the main reason I still use OpenXR toolkit.

Hi team, 

 

I have a frustrating issue with DCS , Pimax Crystal and Dynamic Foveated Rendering / Quadviews & Eye tracking. 

My problems started after a recent patch after which I noticed that Quadviews/Eyetracking wasnt working anymore. 
Everything was rendered and performance was low. 
I had the typical setup: Pimax XR , OpenXR tools ( disabled) , Quad Views and Quad View Companion.

After watching a video about how Quadviews are now native in the Pimax Play app (PP) I switched to the Pimax OpenXR playtime via PP and used the integrated DFR - 
While it worked , the quality was really not what I was looking for ( rendered area too small, outside area to low resolution being very distracting) 
THIS is where my problems started - I wanted to get back to the initial setup PXR,QV,QVC. 

Following problems: 
Sometimes eye tracking works, sometimes it doesnt. I cannot consitently properly recreate the steps to make it work - one consistent thing is that the Calibration via PP doesnt work ( it takes me through the circles, but it can save / identify my pupils) The frustrating thing is - it sees my pupils due to IDP settings, and it works...randomly after clicking around like the primate that I am and somehow it works (combinations of turning everything off, restarting PP, etc.) 
The layers are checked and are in the right order with the Layer tool. I've deleted the PIMAX folder in local/appdata without it working. 

What am I missing? 
I think somehwere there's a config that has some sort of false ID and doenst start up the right software....
Is there a log I can post or anything I can share with you that could solve this and make me have dynamic eytracking and foveated rendering ?!

I had similar grief with the eye-tracking calibration, in my case it turned out to be the USB connections being inserted directly into the mobo. Once I redid everything using the powered Pimax hub it all worked correctly.

I've read conflicting reports however...some people have the opposite experience. I have zero idea why that would be, other than mixing up blue and red slots on different brands and versions of mobos with different USB specs and even incorrectly coloured USB slots or simple user error.

So, try the Pimax hub, investigate your mobo's slots and what priority is given to each and etc.

thanks! I believe we found the solution - It was a conflict with tobii software

@Thanatos31 Same here... updated Pimax Play and quad views in DCS is dead. What conflict was that exactly? How did you solve it? I tried disabling Tobii in the Windows Services to no avail.

Does anyone know how to set up quad views for turbo mode only?  Openxr toolkit turbo mode crashes DCS when removing the headset, which is well known and quad views itself returns lower fps when enabled on my system.

[slughead]

There used to be a way by unadvertising DCS in the QV config file. Scroll up to find details. But I am told this no longer works.

The other option is to switch to Virtual Desktop and go wireless, which is great, and that solves the headset removal problem; plus, you can still use OpenXR Toolkit with it.

Read here https://github.com/mbucchia/Quad-Views-Foveated/wiki/Advanced-Configuration

Shortly: u have to create config file in location mentioned in link and set

turbo_mode = 1

in it.

With Oculus Quest 3 it works fine. With OXRToolkit uninstalled.

You can prevent DCS from closing when removing the glasses by covering the sensor, I have it like this and without any problem.

[subroutine]

Thanks for your replies. I couldn't get turbo mode working with quad views unless it was active but with these settings- 

turbo_mode=1

# Fixed Foveated rendering settings for fallback when eye tracker is not available.
#0.5 0.45
horizontal_fixed_section=0.5
vertical_fixed_section=0.7

[Oculus]
#0.4 1.1
peripheral_multiplier=0.6
focus_multiplier=1.1

it actually runs much better then when I last tried it and the image transition isn't too obvious . Stuttering is almost gone and fps are higher. That's with a 5800x and 3080ti.

Edited January 17 by subroutine

[milit]

@subroutine, try debug_focus_view = 1 and u ll be able to tune fixed sections and smoothen_focus_view_edges precisely.

Also my config eats focus_multiplier=1.2 without fps loss.

Set debug_focus_view to 0 after tuning.

[subroutine]

Increasing that multiplier lowers the FPS too much on my system. 

turbo_mode=1

[exe:DCS]
unadvertise=1

The above does work if Quad Views is enabled in the DCS VR settings to activate turbo mode only.

Really? That would be interesting, because the FAQ that mbucchia wrote said it doesn't work with DCS. He also did say he hadn't tried in a while though...

[subroutine]

It definitely works on my system.

Same here. Maybe I'll give it a go at the weekend....

If I check the Use Quad View setting in DCS I get a black screen loading into any mission. This started today out of nowhere and I have no idea how to fix it.

Pimax Crystal. Previously I was using the openXR toolkit and pimaxXR which I did following a Pimax guide when I got the headset in 2023. But I do not have any of that installed any more.

In the Pimax software I've got pimax openXR Quadviews and pimax central priority rendering checked. OpenXR Runtime shows Pimax OpenXR.

I literally used the headset earlier today. Hopped on tonight to try out something quick and wasn't able to load into any missions. Black screen and when I alt-tabbed I got a DCS has crashed message. I've played around with a bunch of settings, but the only thing that seems to work is unchecking the Use Quad View settings. But I definitely feel like I've lost frames.

PimaxXR has not worked for me in any sim yet (DCS - black screen or ACEvo - view rotated 180 degrees). I’ve always had to return to mbucchia’s Pimax OpenXR

Are you still using the OpenXR Toolkit? If so then disable it. It doesn't work with PimaxPlay Quad Views as the OpenXR Toolkit expects 2 views, but will be getting 4.
EDIT: I see you've said you've uninstalled the OpenXR Toolkit, worth double checking though as this was definitely a cause of black screens based on your description. You can also install https://github.com/fredemmott/OpenXR-API-Layers-GUI to see if it's still there, or are any other API layers that could be causing problems.

If the game is crashing then create a new post along with your DCS log file as that is unrelated to this post.

Raise a new post and attach your DCS log to that after replicating this again. Folk can have a look into reasons why and help troubleshoot.

[Rufuz64]

Uninstall is not enough. I had to reset to dafault and then uninstall!
