Please help with VR on high end system

[Rob G 60]

Hi everyone. Believe me I know there is no magic bullet for configuring Windows, Oculus app, Oculus Tray Tool, and MSFS for VR performance. I know it takes time and patience to get the right combination of options to achieve satisfactory performance.

I have read dozens of forum threads and have watched dozens of YouTube videos about it; but I am just not getting anywhere.

 

Let me tell you what I am working with:

Intel i9-10900 overclocked toi 5.2ghz

Asus GEFORCE RTX 3090

32GB of 3200 RAM

2 M.2 drives and 4 SATA SSD's

Oculus Quest 2

Game Mode OFF, HAPS OFF, MSFS .exe file set to HIGH priority, Nvidia Control Panel settings set for best performance

 

What do I consider my issues:

1. Everything outside the plane is always jittering, no matter how low I set everything

2. I have a really hard time reading the instruments, even in a Cessna 152 (yes I have Reloptix lenses in the headset)

3. Even text on the screen, in VR, seems all jittery.

All of my testing is being done using Oculus AirLink.

Now I don't expect anyone to give me a magic formula. But I spent a lot of time and money building my PC and I feel I must be doing something very wrong in my methodology, to be having such crappy results with such good hardware. What I'm hoping is that maybe someone can point me to an article or a video that is known to be very informative to help someone new to develop a working VR configuration. I just don't seem to know where to start and how to progress towards success. There are so many components (Oculus app, OTT, MSFS, etc). I have a very good internet network at home, WiFi 6 mesh router in the room with me, hardwired to the main router in another room, PC hardwired to the mesh router, Quest 2 connected to dedicated WiFi channel.

I don't want to be spoonfed answers (although it would be great LOL). I want to be pointed in a direction to learn where to start; what to do first, what to configure first, anything that I can read/watch to help me see how to get the most out oif this expensive gaming PC I built.

It's particularly frustrating for me because I am actually a retired computer specialist and I thought it would be easy to figure this stuff out. But I have to admit I am lost and in need of guidance. 

Please someone give me some guidance. All help will be so greatly appreciated. And if any if you gurus happen to live in Las Vegas, I would even poay foir hands on help (figured I'd throw that out).

Thanks in advance,

Rob

how does it run without your vr switched on?  super high fps and smooth?  

what's the rendering resolution in vr?  check with fps display in developer mode. what graphics setting in vr mode?  all ultra?  start low and see if baseline sim is ok, gradually increase graphics settings.  and high rendering resolution with high supersampling will definitely affect smoothness.

i have similar system but using hp reverb g2 and it's very nice.  

and i wouldn't set the priority to high.

Set resolution in the occulus app to full.  Slider all the way to the right.  80 hz is what I use.

MSFS vr settings, Render resolution 100, Ultra texture resolution.  Volumetric clouds start at med to high.  LOD sliders start at 100.  Start med on everything else and work your way up.

OTT.  Basically I went about it by trying to get above 30 fps constant.  Once you can get that set ASW to 30 hz which results in 27.5 fps, this for me got rid of the jitters.  But the key is to be above 30.  I usually try to pin it at 40 fps then set asw to 30 hz, this is very smooth for me, no jitters at all.  (Use the HUD Display Performance to check fps).

Text resolution is a tough one.  Setting the pixel density upwards to above 1.0 will help and it get's better the higher you go but at the cost of fps.  I use 1.1 or 1.2 depending on area and what the fps are. (Have to toggle out of VR mode, change setting then toggle back in to vr mode)  You can check pixel density in the performance hud.  Ensure that the occulus app resolution is maxed and render resolution in msfs is 100.

Tips for OTT:  Reducing FOV to lower settings increases fps for me.  I have it set to .85 Hor and .65 vert.  Experimentation is the key, but to change the values you have to toggle out of vr mode, save changes for FOV, then toglle back in.  

 

I currently have high to ultra settings in msfs and without asw mode and 1.1 pixel density I sit at about 32 fps at an airport but that usually jumps to 40 pinned when in the air.  I keep volumetric clouds set to high and 130 on the lod sliders.  .85,.65 on fov. 

But as _kdfw stated, start at lower settings and work your way up keeping the above in mind as you go.  

For me though, I still find the view in the distance and the hud text slightly blurry, especially on the g1000, I find I have to lean in slightly or use the vr toggle (which I have set to the right mouse button).

Thanks so much for the guidance. I have tried to follow it and the technical result is as you said; I got the sim to maintain over 30 FPS (almost 40), then I set ASW to 30 and saw 27.5 in the HUD monito,r like you said I would.

However, while the cockpit image is not particularly shakey/jittery (although not that clear either), the outside ground terrain is stil pretty jittery and the landscape seems like it's always being painted as I arrive to an area.

Can you offer any more insights to help guide me with this? Thanks so much!

I've found that for me, the latest updates to the sim, vis a vis fps, makes it simpler to run with asynchronous timewarp turned off.

[slashed2 53]

So that's interesting HiFlyer.  I actually have the jitters at the departure airport so set the 30hz limit there since my fps may be around 30-32.  But once I get in the air my raw fps is usually between 37.5 and 40 fps.  Curious what the OTT settings are under Quest Link tab?  I have it at 300 bitrate, 3648 encode resolution and Distortion Curve at low.

Also, curious as well which nvidia driver you are using?  I had to revert back to 466.27 since the lates nvidia driver was conflicting with occulus app when using OnAir.

 

[HiFlyer 9,359]

I turned all the oculus tray stuff to default.

I think at this point OTT might cause more issues than it solves with the current version of MSFS.

And of course, I'm using the link cable. Have not tried wireless in quite a while.

Driver is 471.96

 

[slashed2 53]

Yeah, I just use it for convenience since it's easy to check fps and pixel density, I have everything else off.  The ODT handles everything in OTT anyway at this point.

The 471.96 was causing Crash to Reboots every time with onair so reverted back.  Not one CTR since so may just wait till the next nvidia driver comes out and try that one.

[slashed2 53]

To the OP, try setting the occulus app to 90hz or even the experimental 120hz.  I've just tried 120 hz and was getting 40 plus fps and didn't use the asw setting at all and saw no jittering at all.  The only time I get jitters is at an airport when first starting out and they may just be due to stuff loading in.  I usually push back then switch to VR so it takes a minute for things to settle down.  Otherwise may try searching online to see if you can find anything.

[slashed2 53]

Also, there's a great guide here, albeit a different direction: https://forums.flightsimulator.com/t/tnt-quest-2-settings-sharp-and-smooooth/367530/5

I just tried these settings and like them.  Cockpit seemed more clear and the ground textures seemed pretty good, so now I'm torn between max res and 100 render scale to get resolution or using lower render scale and higher pixel density.  Will try the pixel density route for a bit and see how it goes.

Maybe a slow or intermittent internet connection. Bad wifi, no Ethernet cable, something along those lines. But I have found that shaky thing you describe if I have Oculus Tray Tool ASW settings cranked up to high or too high in the sim with the supersampling.
