VR Issue: Incorrect Aspect Ratio (OSVR HDK2)

[flash_]

Using OSVR HDK2, which is supported in SteamVR for this game. I am having an issue where the HMD image is too squished horizontally. When you tilt your head it creates a skewed image that is very disorienting. Other SteamVR titles that I own are still functioning normally. Have up to date GPU drivers, SteamVR drivers, OSVR firmware, etc. Have attempted both direct and extended mode with no change. Have attempted current live and beta builds of SteamVR.

Please note I am having the same issue on my Pimax 4K which is essentially recognized/the same as a DK2 from my understanding of it. This effect is most pronounced with vertical head movement there are severe distortions of clouds and cockpit frame when doing this. I thought to myself it appears like the FOV/ head position is wrong.

There are new lines in startup.cfg like or_width and or_height. Maybe entering manually your HMDs resolution will fix it.

I tried it but it didnt change anything.

[C6_lefuneste]

I had the following lines in startup.cfg:

 

    or_enable = 1
    or_height = 1920
    or_hud_rad = 1.50000
    or_hud_size = 0.75000
    or_ipd = 0.06300
    or_width = 3456

 

I did not understand the values _height and width. I tried to change them, but it does nothing and they went  back to their values...

Do you have the same lines ? Are they the same for Rift or Vive ?

[LonnyEnds]

I had this for Pimax, will be testing further this weekend. 

 

or_enable = 1

or_height = 3328

or_hud_rad = 1.50000

or_hud_size = 0.75000

or_ipd = 0.06400

or_lens_offs = 1.00000

or_width = 1872

[LonnyEnds]

Ok guys after some investigating I have made a bit of progress. It appears the startup.cfg Is getting its values from Steam VR. If you change supersampling level and start IL2 then exit the numbers in startup will change. My numbers above make sense since I had Supersampling set to 1.3. The native resolution being 2560x1440. This solves the mystery of why changing the startup file has no effect. The question is now, is there a way to manually configure Steam VR resolution/ change the aspect ratio. In my case I am at 16:9 which I wouldn't think would be so distorted but it is. I am going to try some different versions of Pimax software to see if I can get better results. Unfortunately supersampling affects both width and height equally. If we could set a custom resolution or set supersampling for each separately we could correct this issue.

I submitted a ticket through Steam under SteamVR's page. Hopefully they will take a look at it. OSVR is listed as officially supported for this title so they should. Other folks having this issue should also submit tickets.

[=TBAS=Sshadow14]

there is more settings for that config if you have a ORift connected..

these might help you guys as i think thats the problem with like Pimax and stuff..

Look at FOV options also the Scaling of 0.750 and stuff

 

    or_enable = 1
    or_fov_gui = 0.40000
    **or_fov_h = 1.0000**
    **or_fov_v = 1.00000**
    or_height = 2016
    **or_hud_rad = 1.50000**
    **or_hud_size = 0.75000**
    or_ipd = 0.06080
    or_lens_offs = 0.02774
    or_width = 1497

The ones in ** ** are those i think that might help you lot..

Maybe try run the Pimax with these ORift Settings but JUST change the Resolution to what Pimax uses.
Or
or_fov_h = 2.0000 )to reduce that squashed Pimax FoV

Please note i don't own a VR im just trying to help with the above info i saw lastnight..
Sorry if im wrong

Also very keen to see how Pimax goes i always prefer to Support the guy selling X product for minimal profit (pimax) unlike others selling Rift or Vive for 200% profit.

Lonny hello...I am using the 1.2.57 latest drivers and latest Nvidia drivers and I am not getting the effect you are describing. I also set my Pimax too video mode and changed the resolution to 2560x1440 as it was at 1920x1080 as default. Then back to Pimax mode for gaming.

I agree the latest driver is close to the aspect ratio of the 1.1.92 driver as well. For IL2 the scale feels better in latest driver.

[LonnyEnds]

Yes I can confirm with the Pimax at least the 1.2.x seems to be a much better aspect ratio that 1.1.92. I will have to double check the native resolution that these drivers are requesting of SteamVR but I had best results from taking my native resolution and calculating what supersampling to run to give me as close to 2560 height. (The width is now something like 2100 vs the 2560x1440 of previous software. Overall pretty happy with it. Just need to get TrackIR working with it so we have proper 6DOF.

[71st_AH_Mastiff]

make sure your in landscape not portrait modes..

[LonnyEnds]

So with Pimax 1.2.53 I am getting: 

 

or_enable = 1

or_height = 1989

or_hud_rad = 1.50000

or_hud_size = 0.75000

or_ipd = 0.06300

or_width = 1612

 

Whereas the above videos were from when it was putting out 2560x1440 to startup.cfg. Obviously there is a huge aspect ratio difference between these two and with the above settings the distortion is very minimal/gone. 

 

It looks like the OSVR guys will have to rely on either OSVR, SteamVR, or IL2 to be able to change the resolution.

Been almost a week since the last post. Steam technical support (SteamVR) says this is a problem on IL2's end. There has been multiple driver updates for my GPU and even an update to the OSVR drivers. The issue still persists, unfortunately. Has anyone made any progress?

[LonnyEnds]

Possibly try Nvidia control panel/DSR? I haven't used it but I know guys have been trying to mess around with it for the Pimax. Also have you tried deleting your steamvr settings file? I know when changing drivers for Pimax some people solved the device being in portrait mode by deleting this. Should be in:

 

 

C:\Program Files (x86)\Steam\config\steamvr.vrsettings

 

As default. It is a .cfg file if I remember correctly.

 

Only other thing I can suggest is see if anyone in the OSVR forum/world can help.

I opened a ticket for BoS support and they answered me that this is a problem in the headset manufacturer side...

I asked them the steamvr output used by Il2Bos to set VR FOV but had no answer.

I made some testings with 3dmigoto lib and get a correct H/V ratio, but this create a "cinemascope" effect because I had to compress the horizontal view by a factor 2, so there are two black band on top and bottom of the view...
