General VR visual issues viewing external objects[minor]

[left orbit]

I'm assuming this has something to do with the way exterior window views are rendered, but when in VR observing another vehicle (this is especially prominent in the LM, where it is instantly headache/eye strain inducing) through a window, the render of the external craft doesn't seem to account for being viewed between two eyes—or account properly for head movement, which gives off strange abberations in movement, distance perception, and in the case of vewing the CM/SM from the LM, a complete lack of visual field separation where the craft is rendered in identical positions between the two eyes which causes a good bit of discomfort.

Thanks for the report, how is this in for example Gemini when performing a rendezvous/Docking with Agena ?

I haven't tried gemini/agena in vr yet but i can give it a go at some point and get back to you-- though if i had to estimate, its probably similar since it doesnt seem like the external crafts are rendered in the same 3d space as the main active craft.

[stone flicker]

yeah but an eye-space scaler is used to map the things together in VR. However, I have been playing with the idea of just rendering it all in the same space if possible, at one point, starting with Agena

It can be done by making the real external object invisible when inside the cockpit, and then transform a twin in the cockpit space using the relative position and orientation between you and the actual Agena

ill try to test agena for ya maybe after this weekend, we're having huge power outages/internet outages here due to windstorms but ill let ya know

Thank you and no rush!

best of luck with the storm 😮

ok a little bit more from the LM atleast; it looks like the outside perspective skews appropriately with headset movement, but not general camera movement; this was observed on the lunar surface looking down from the left-hand window and noticing moving the camera using the thumbsticks/camera controls in vr does not move the external render world space. Head/parallax is rendered as expected, no problems there. The weird part is that because of this, you can observe the landing leg/ladder on the right hand .. from the right window, which is a little trippy but not bothersome. Just a small thing!

[stone flicker]

Ah, great insights, thanks!

maybe the refresh rate of the external layer lags a frame or two behind, refreshing at the wrong stage in the pipeline

[left orbit]

it looks (atleast in regards to actual headset movement/positioning) to update pretty seamlessly i think as far as latency and fidelity goes, it just seems not to update for general camera movement using the thumbsticks or arrow keys

I use to have 90 fps in reentry 1.0 in VR (Varjo Aero Nvidia 4090) after the last update i get 10 fps !!!! what is going on ??

[stone flicker]

What spacecraft did you use to have this in?

Could you try to revert back to an earlier version just as a test?

Sounds trange tho, most of the changes in the last patch is mostly meta and logic changes that should to affect performance at all. The main focus since 1.0 has been to correct general reported issues in the 1.0 scope so this applies to most of the updates since 1.0.

[glacial widget]

How do you revert back to 1.0 ?

[glacial widget]

let me try to downgrade using the Steam DB command line

[left orbit]

ive noticed at specific times in LEO around the night/day terminator frames will get locked around 10fps-- timescaling past this region resolves it but it is not consistently there or guaranteed. I havnt a clue what produces it

is the 10fps for you constant? or inconsistent/skippable

[glacial widget]

I also did little more search and appear the issue occur only when I enable the VR controllers if I just use the mouse that doesn't happen, I sent you an email with more details I am copying here the email is constant 10fps

Dear Dr. Wihelmsen

My name is Franco De Flaviis,

I am a faculty at the Electrical Engineering and computer science department at the University of California Irvine (originally from Italy), and in the free time very passionate of anything relate to flight simulation technology. I often play X-Plane, DCS and falcon BMS all exclusively in VR, as I truly believe Flight sims are the real "Killer app" for VR.

I recently purchase Reentry on Steam (v1.0) and I was literally blown away on the amount of research and work you had put in this simulator. While other simulators like Orbit exists been in VR inside those modules has literally no equal and make the overall experience fantastic ! (even better than visiting a real Space Museum !)

Please keep up the extraordinary work and make sure to keep up VR always alive in the simulator that really make the simulator shine !!!!

When I will have more time I will consider helping with the Italian translation if you need.

One little note:

I have the following system (Asus with 13th gen i9-13900, Asus RTX 4090 Varjo Aero headset with Lighthouse vive controllers wands) In v1.0 I had fantastic 65-90 fps even with medium-high settings. Now since the update to 1.028 I notice that I would get similar fps if I only use the mouse and don't turn on the controllers (not very immersive) but as soon I turn on the controllers the frame rate drop to a miserable 10 making the game completely unplayable ?!

I hope you can look in to this whenever you have some time as it is really pity not be able to interact with the cockpit as in v 1.0 !

Have a great day and keep up this fantastic work !!!!

Franco

the VR controllers seems to be the culprits

[left orbit]

interesting

[glacial widget]

looks like some kind of bug in sycing with the controllers

I will try with the valve index I have an old one sitting somewhere to see if it is specifically related to the Varjo OpenXR implementation or to any lighthouse type of controllers

I am in the most simple spacecraft Mercury mission "In Orbit"

[glacial widget]

I Have done little more research (hard to make sense ...) and found few more clues, if I move the game folder outside the steam folder (C:\Program Files (x86)\Steam\steamapps\common\Reentry - An Orbital Simulator) and put on C:\temp\Reentry - An Orbital Simulator I get back the high frame rate even when the controllers are ON. This is true for both versions e.g. 1.0 and 1.0.28 so is not exactly version related. Attaching a couple of snapshots the difference is massive.

so clearly is not related to the CPU or GPU neither to the move from 1.0 to 1.0.28

[glacial widget]

Ok I found my old Valve index with the valve index I have good FPS in 1.0.28 regardless where the executable it is so not issues there. This is really odd !!! I would suspect something to do between the varjo OpenXR implementation and the steam VR latest update not really sure what to think. I can probably try an older steam client with the varjo headset to see if the issue goes away

[left orbit]

possibly; i've noticed the occasional 10fps lull for a few minutes and its very interesting to me that it is consistently 10fps, no more no less.

What’s up?

[glacial widget]

I wrote a summary

of what exactly happen did you see here, BTW nice meeting you and congratulations for the amazing work !

I am not familiar with discord not sure what you see

[glacial widget]

I am not familiar with discord did you see my reply ?

let me copy over here again

I sent you an initial email to congratulate your work and mentioned the odd issue

after that I have done some more research and find some interesting points

you can see the massive difference

Sorry, that "What's up?" message somehow was auto-generated from the iPhone (potentially I hit some kind of touch button on the notification when I received it from my phone), it was not an intended messaged. I have not yet read this thread so I will catch up (I am on holiday so bit slow these days)

[stone flicker]

Ok, I went through it all now and thank you for the detailed reports. Once again, sorry for my random unintentional "What's up" message from yesterday. I am curious if some exception or something happens when you are using the normal controllers that causes this. Maybe you could get into that low-fps mode, so the issue reproduces, and then let it run for a bit like that before closing the game and then sending me the logs (the logs get overwritten for each time you start the game)

No worries I am also on Holidays ! That the time I get to play ... Ok I will get the 10fps solid and collect the log file, at this point I am suspecting something between steam VR and Varjo open XR but still good to get to the bottom of it

[glacial widget]

I am sending the file from this directory C:\Users\Administrator\AppData\LocalLow\Wilhelmsen Studios\ReEntry

let me know if you need any other log for this session I had 10fps solid

[stone flicker]

Thanks, will analyze this when I get back into office-mode! 🙂

Petri, while replacing the battery in one of the vive wand I have made a small hack to better use Reentry, and I would like to share the STL files for people in the community to be able to use them. I have use the Reentry logo in the first page of the project description, but I want make sure is ok on your end before I publish it. If not I can simply remove it.

[stone flicker]

This is ok! 🙂

Let me know when its out by posting a link to it here as well? 😄

[glacial widget]

Just Posted here the update version

[glacial widget]

BTW I am still getting the 10fps frame unless I move the file outside the steam folder in VR let me know if you will have a chance to look at the log to see what is the culpitris

[stone flicker]

Thanks, been trying to figure out why this can happen.
