Has anybody been able to eliminate cockpit stutter in the Reverb G2 with motion projection turned off?

Sweet, 100/90 is a nice place to be at, though I haven’t gotten good results with my G2 and Motion Reprojection with SU5, I think something is broken. I can tune it to be running mid 40’s FPS-wise, but then once I turn on motion smoothing, it locks to 22.5, not even 30.

Check out the settings suggested by YouTuber PIEINTHESKYTOURS. It’s working very nice and smooth for me with about the same hardware as yours.
Anti aliasing however is totally broken now after SU5 and the shimmering is really bad.

Forgive my ignorance, but I’m not quite sure what the OP means by “cockpit stutter” in VR. I get quite a good cockpit experience with my G2 after SU5 performance wise, now that Radeon rigs no longer CTD all the time. I’m using 100% OpenVR 80% RS in game.

The cockpit is clear and instruments easy to read and, more to the point the colours are really good inside in the planes I have used so far (unlike the scenery outside, which is often washed out with overbright clouds, which we all seem to be suffering from atm).

I’ve only tried motion reprojection once and it was a mess, with an annoying red or whatever window intruding with illegible type saying something or other about I know not what. Then the sim crashed.

I’d say my experience is about as good a Pie in the Sky’s recent videos and my settings are almost the same. Not surprising, as we have similar performing PCs.

I’m driving my G2 with what I guess now classes as a good mid-range rig (i7-9700 3.6GHz, RTX2080ti, 64 Gb, no OC, water cooled). Have to say after SU5, I’m getting extremely smooth performance in GA and astonishingly no stutters. I’ve been able to push some graphics setting up a little and now run at 100 LOD and 80% render scaling. In the JF Warrior even over downtown LA with photogrammetry on (used to be a complete no-go area performance wise!) frame rates were pretty solid 35-40fps and smooth:

The one thing that really puzzles me is how people can have such different experiences. With your rigs, you should be zipping along better than me :wink:. As for motion reprojection, tried it, didn’t like it, don’t use it. In fact pretty much stick with default WMR and OXR settings. What you fly obviously makes a big difference, but since you’re talking about the propeller visuals - assume GA too. I did also try the DC6 for an hour or so yesterday just to push things. Only had time for a couple of circuits at SBCF in Rio, but it’s a pretty complex ‘detailed’ airport. Still managed a smooth 30-34fps, with just the occasional dip to 29 when looking around quickly.

Good luck getting it sorted!

For reference, here are the VR settings I’m currently using:

Great post, thanks! Are you not getting anti aliasing issues (shimmering) post SU5? Many of us do, curious if it affects you too?

Yeah - seen a lot of comments on that. As for me, no - not really any problem with shimmering that I’ve noticed. I did play around with antialiasing … FXAA does get a bit more performance but pretty bad shimmering (you have to imagine it’s the effect of heat haze :laughing:). TAA is much better, and seems to be manageable now.

For what it’s worth, I found motion reprojection caused all sorts of ‘tearing’ and ‘wobbling’ (for want of a better description) in the scenery as well as the propeller artifacts … the main reason I didn’t like using it even though it can do a good job of smoothing the display.


Just checked … only place I’m getting significant shimmering in VR is around very thin model items (poles, railings etc.) against a distant background (as ringed in the screenshot, SBGL). Elsewhere, nope, pretty steady

(Screenshot is 2D … so a little better than what I get in VR :wink:)


Specifically on anti aliasing in VR, if anyone hasn’t found it yet - see this thread.

By cockpit stutter, I mean when I look around the cockpit, it judders. It isn’t smooth but rather jerks like I’m missing frames. It only happens when I turn motion reprojection off, and dropping the render resolution makes minimal difference. It’s horrible.

Conversely, with motion reprojection on I get a butter-smooth cockpit and can crank the render resolution to 100 in OpenXR and 90 in game with no performance hit. I was getting some warping around the propeller with motion projection on but I downloaded a fix from flightsim.to and that’s no gone.

Overall, I’m having the best visual experience I’ve ever had with this new patch even if I seem to be doing it the opposite to everone else. Turning motion reprojection off just doesn’t work for me for some reason, but turning it on doesn’t give me the warping and tearing either now that I’ve downloaded the mod fix so I’m happy either way.

For me the shimmering is actually improved in the new patch as I’m able to run my Reverb G2 at full resolution now.

I think it might be that I’m running at higher settings and resolution. For me clarity is king and I’m now running 100 render in OpenXR, 90 in game with almost everything on ultra. I have shadows on too.
Running at like 70 render scale in OpenXR looks blurry to me so I crank everything way up.

I find with motion reprojection off it just doesn’t run at those settings whereas with it on it runs butter smooth for the most part.

I only fly slow GA craft, Cessna 152, Top Rudder Solo, Savage Cub etc the motion reprojection might be more annoying in faster moving craft? But the propeller fix I downloaded from flightsim.to has massively improved it. I didn’t notice any warping or tearing at all yesterday.

Nice. I reckon I could push render scaling to 100 in GA. I will give that a go and play around with reprojection again too.

The way you describe judder in the cockpit … I do get that in the DC6 when moving my head (translating), but not noticeable just turning (panning). Neither noticeable in GA such as the Warrior.

Overall, really enjoying SU5 … having said that, just had my first CTD in months at the point of touchdown after a 1hr flight in the DC6. Gonna try again without live traffic. There were aircraft every which way … in front, behind, on the runway and - judging by a very ominous shadow - above me too. :laughing:

If you try motion reprojection I definitely recommend downloading the propeller mods on Flightsim.to

It’s made a huge difference to my Cessna 152 experience, practically eliminated that warping appearance and tearing. The only degradation I noticed due to motion reprojection yesterday was when I went into external mode and move my head quickly from side to side, which would tear a little. But slow movements were fine. and I had no issues at all in the cockpit view.

To me, “everything”(EFIS displays. buttons. clouds. buildings etc.) is shimmering since SU5. Way way worse than it was in SU4/SU3.
I have more or less always run with motion reprojection off and had a nice smooth experience (even down to like 24 fps). With SU5 I’m now getting a lot of judders - especially moving head up/down still with the same settings. And of course the visuals overall looks downgraded with pop-in, LOD, shimmering etc.
People say they get increased FPS - me not so much, maybe a few FPS, but definititely no significant difference.

Hi buddy!

I am in the same boat with you and I am searching now the forum for any solution.
I understand perfectly your problem and is the same for me.

My rig’s specs:

AMD 5950X (haven’t tried yet to turn off the virtual 16 cores and keep only the 16 physical ones)
128GB Ram

I have the same visual effect in the cockpit.
I’ll try some more in game settings tomorrow.

Take care!

Almost same experience here, I’m running 100/100 with a mix of med-high-ultra settings, LOD=TLOD=200. In contrast to you, I was also experiencing the 22.5-bug before SU5. My average FPS for a specific pre-recorded test flight with the DA40 TDI are 34, my 0.1% is 25, MoRepro will still lock to 22.5. However, again in contrast to your experience, MoRepro will switch to 30 when I’m pretty high above the ground, where I get around 40…45 FPS without MoRepro.

Are you running via SteamVR or WMR? Are you setting MoRepro to “automatic” or “always on”? What NV driver and non-default settings are you using?
I’m on 471.41, my only non-default settings are power management (maximum), ani filtering (performance) and VR pre-rendererd frames (2).

HP Reverb G2 is a trash for me. Probably all other VR headsets would be trash as well. The biggest mistake in my life is to bought a VR headset. The image quality is so bad, almost everything is blurry outside of the cockpit when you look at far. On the other hand menu and edges are blurry as hell.

I think VR headset manufacturers should put a note on headsets and tell people that the look and graphics quality will never be the same as normal 2d monitors and surely will never the same as youtubers source recorded videos.

With this much of blurry and stutters, low frame rates between 28-35, you will wear a glass in 5-7 years because of eye problems without a doubt. It also results a motion sickness because of low fps and blurry. Maybe I will try VR again after 6-7 years when Nvidia release 6k or 7k series of RTX GPU.

My advise to people who plan to buy a VR, dont do it just after watching youtubers videos like I did. The graphic quality is not the same on the headset as recorded video in youtube. The video on youtube is recording the video from the source of the GPU which does not have blurry textures. Make sure to go somewhere and try VR for your self, then buy it if you like it.

And yes I have RTX 3080 with 10900k @5.1 OC and did all the configurations including openxr etc… I just wanted to share my experience.

Whoa! Sounds like one dissatisfied customer. While I admit that vr is not quite perfect yet, I can’t even imagine flying any simulator without it. I’ve been waiting on this tech for so many years and I’m glad it has happened in my lifetime.

I, however, have had an issue with my Reverb G2 since my purchase about a year ago. When sitting in the cockpit of any aircraft, it seemed that the higher I had my volume level, the more bounce or jitter I would get. The slightest tap on the side of the headset would immediately be seen as an irritating jump of the cockpit or instrument panel. It is almost as if there is a loose connection inside the hmd. My cable is snuggly snapped into it’s socket, and moving the cable around never seems to affect it.
I could steady the headset with both hands and the jitteriness appeared to subside and the image was more stable. So, after removing the speakers from the G2, I put on my Sony headphones and cranked up the volume while in the cockpit. Low and behold, no more jitter from the increased sound. I still get the jumping if I tap on the hmd , but at least it’s not constant like it was. Anyone else experience this condition? Kinda hope I’m not the only one.

Wow that’s an interesting one. Can’t say I’ve experienced that with my G2; although they are sensitive … in certain angles (looking hard down to find the fuel cutoff for example) I’ve had my display ‘twitching’ because of my own heartbeat.

Very sorry to hear @AlienVisionXX’s disappointment. Compared to 2D monitors, they have a very long way to go and are compromised in terms of field of view, clarity, resolution and dynamic color range. I agree - VR is pretty over-hyped at times. Having said that, I’ve accepted the compromises and now only fly VR … using the screen is now like watching a movie of someone else flying.

That’s good advice.


I have experienced this as well. In the G2, I get bounce/jitter all the time. I spent weeks troubleshooting it, thought maybe it was a problem with inside out tracking with my AMD-based system. Spent weeks on an RMA process.

In the meantime, I got a Valve Index and Pimax 8KX which do not have this problem.

The G2 will bounce with my heartbeat. I am not kidding. I hadn’t considered audio, but that makes sense too.

Using WMR, MoRepro I’ve tried on both settings, and I don’t see a difference.

I’m using 471.41. Non-default settings:
Texture filtering - Quality: Performance (along with the 2-3 other settings that this setting controls)
Vertical sync: force off
pre-rendered frames

Also, I set power management to normal as I’ve heard that “maximum” is not the best setting for VR where consistency is arguably more important than raw frametime

Motion preprojection will lower the frame rate compared to it switched off, as it defaults to the lowest stable frame rate you can get and locks it. But it’s so smoother as a consequence. I’m happy now and have just stopped worrying about turning off motion reprojection. With it disabled my frame rate is higher, but my cockpit jitter is just unpleasant to use.

If you’re going to use motion reprojection though I recommend downloading the propeller mod fixes for the planes you fly on flightsim.to. It eliminates the warping for me.

Now I’m very happy with the sim and motion reprojection. I wish I didn’t need it, but I just cannot get stutter free performance without it.
