Can you please post all your settings? Including driver version, OXR settings, MFS settings etc? I’m not sure what can be wrong with my system or settinngs to not get the same results some other people are getting. And I do have one of the better 3080s supposedly: EVGA FTW3 Ultra, higher clocked and better binned then most… I wonder what can be wrong… I’ve never seen anything above 31FPS. Usually, even in 152 lessons - high 20s...
Also, what do you use to measure FPS - dev mode counter is not visible in VR

i'd agree with the op on the settings, except for me openxr rendering scale=50% and set the rendering in fs to 100% give good image quality.

for my old rig to run smoothly, i also lock frames using nvcp to 25 so that looking out the side window is less prone to stuttering.  limiting frames also seems to give some headroom for effects so i can set the windows effect at ultimate.

 

I wonder if limiting the frames has any effect of the headset. If so, consider locking at ca. 32 FPS, if you use 90Hz headset, as 30 results from dividing 90 by natural number (3).

excuse my ignorance but what does ca stand for?

I think he means "circa" or "about" or "around", something like that.

- "Motion Reprojection" - DISABLED!!! This was the game changer, no more stutter, judder, the MFS2020 settings balanced to produce ca. 30FPS, this seems low for VR without reporojection, but for me it's much better to have fluid ca. 30 FPS instead of constantly changing FPS with the repojection enabled.

I've looked at this issue extensively and I don't think what you've stated is entirely fair.

You are probably not allowing reprojection to work effectively if you're not seeing a significant difference - same thing happened to me until I figured out what was going on. it's definately possible to get super smooth frames. I do have butter smooth frames and I mean BUTTER SMOOTH on my 2080Ti with reprojection enabled and when I turn my head around the cockpit it's super smooth - no bluring of artifacts when looking out of the side of the window or around the cockpit. Without reprojection it's ok but I get a slight judder when panning across the cockpit and it's definately not butter smooth. Maybe a 3070 is the difference but I can't see it.

So to give reprojection a chance you need to set a low render scaling in OXR to 65% (any lower and you hit a distortion bug) with runtime preview enabled. In MSFS for my 2080 Ti I set render scaling to 70% and use meduim settings. I have slightly overclocked my GPU by 150Mhz and my 9900K has all cores locked at 4.7Ghz. But oh my I was flying around LA with all that photogrammetry and in bad weather, London too with Orbx landmarks and EGLC and it was butter smooth, incredible infact in my G2, it's not pin sharp but not too bad either and there are still some reprojection artifacts but these are not noticible if you don't have a prop out the front - I was in the Icon A5.

Absolutely amazing experience, but without reprojection I've just never had it running butter smooth, sorry.

This has been my experience also, however I have been struggling to get motion reprojection to kick in and/or stay on.

Without motion reprojection I get 30-40fps in VR with OXR70%, TAA70%, Terrain LOD at 100, and most other settings set to medium, which looks great anywhere forward of the wings, but I get juddering looking straight down.

My issues is when turning on motion reprojection I cannot get it to reliably kick in even at OXR50%, TAA30%, Terrain LOD at lowest.  I have even set my headset to 60Hz which should cause motion reprojection to kick it at anywhere over 20fps.  When it does kick it looks amazing, but when it stops working, < 20 fps is very difficult to fly.

I am really surprised that enabling motion reprojection would cause nearly a 50% drop in fps, and because of that I think most people just leave it off.

What is also frustrating is it seems to turn itself off when you wouldn't think it would.  For example, I was flying around Florence Italy in the Extra 300 under 500 feet, and looked amazing, then when I left town and was in the surrounding hills, that is when it turned off.  I would have expected the opposite.

System specs:  Ryzen 5600x, 32GB DDR4-3600 RAM, RTX 2070 Super, HP Reverb G2.

After playing around, I found that Reflections seemed to be what was detrimental to my motion reprojection experience.  

Also, if you can stomach it, I recommend you try setting your G2 down to 60Hz. This will allow Motion Reprojection to work all the way down to 20FPS allowing to bump other sliders up.

For me, it is so immersive, that after a couple minutes, I no longer notice the flicker.

Here are the setting that work best for me at 60Hz:

Render Scale: OXR65,TAA70 (OXR70 works, but motion reprojection turns off occasionally)
Terrain LOD: 70
Terrain Vector Data: Ultra
Buildings: Medium (big hit w/ motion reprojection on Ultra)
Trees: Medium
Grass and Bushes: Low
Objects LOD: 200
Volumetric Clouds: I usually fly in clear skies, so haven’t tested
Texture Resolution: Ultra
Anisotropic Filtering: 4x
Texture Supersampling 4x4
Texture Synthesis: Ultra
Water Waves: Medium
Shadow Maps: 768
Terrain Shadows: 128
Contact Shadows: Low
Windshield Effects: Ultra
Ambient Occlusion: Off
Reflections: Off (even on LOW makes motion reprojection unreliable)
Light Shafts: Low
Bloom: Off
Glass Cockpit Refresh Rate: Low

I expect the same quality for G2.

Thank you for your kind words! I'm glad this is helping others!

What is detrimental is when the frame rendering time is exceeding the frame time budget + some room for motion smoothing computations. When you enable reflections you're just adding more computations which might be just enough on your system to pass the threshold of the frame time budget.

I've reported (I don't remember if in "My VR Settings - Index" or "My VR Settings - G2") that it takes on my test system 9700K+2070S about up to 40% rendering resolution / 25% rendering resources, when enabling motion smoothing. In other words and in practice, if I can sustain 30fps at 2k x 2k render pixels (effective, not post-process res. i.e. not OXR scaling), I need to lower to about 1.5k x1.5k render pixels to sustain 30fps with motion smoothing.

The latest SteamVR 1.16.8 with its new 6:1 motion smoothing (5 new frames from 1 render) allows lowering the effective fps with is another way to cope with this in extending the frame time budget, instead of lower the amount of work within the frame time. As of now, SteamVR is giving same visual quality as WMR but with more control and leeway. For example I can now configure FS2020 with higher settings with the Index than the G2, more render pixels than the G2 as well, and all with motion smoothing working great, in exploiting the 5:1 re projection SteamVR is now capable of achieving. In other words: 22.5fps displaying as 90fps! There is another advantage to this I came aware of lately: because FS2020 is rendering at only 22.5, it makes EFIS refreshing closer to real avionics AND it is taxing less the overall performance as a consequence.

I've posted about this a couple days ago here:

maybe so, but you can still see the outside world moving at only 22.5 FPS. Windmills look like they are out of an old fashioned movie for example. 

@Ianrivaldosmith you are right, but in all honesty, this probably is the only moving element in the simulator where you might see a difference and even then, unless you're flying close to them, it doesn't  show this much. And this is also because of the 2070S of course, otherwise maybe with a 3090 I'd push this much farther 😉 VR is full of compromise, and I rather trade windmills for the sake of the overall experience.

I’ve a 3090 and to be honest msfs needs some work in terms of performance.
