Btw, is there any way to disable the 2D mirror?
Or at least cut it in half and render only one eye?
I need a tiny amount of additional performance to hit a quality/frame rate ratio I like.
Also: I wish we could fly in VR and still take nice 2D screenshots. I have a few ideas for flights but the bad image quality will ruin the AARs.

I just flew over my houseā¦in VR, in a Grumman Gooseā¦ 
So hereās something interesting I found out today. If you are using reprojection and you are experiencing major artifacts around the prop disc, mess around with the prop RPM. You can quite often completely eliminate the āwobblesā. Not really a fix, but it is a usable workaround and shows that this is something that can probably be fixed by the aircraft devs if they feel so inclined.
On three hour legs, when I see the left seater looking out the window to the left, I enjoy just minutely tapping the right engine prop RPM every twenty minutes or so to de-sync them and make the flying pilot wonder what is going onā¦
You Sir, are a very bad man! 
So, Iām sure this is common knowledge, but I only learned this yesterday after watching a YouTube video review. The reviewer mentioned he was getting a lot of choppiness and someone commented that he probably had the rolling cache on. Due to my rural internet connection, I have always had the cache selected on. Well, even with a less than great connection, turning off the rolling cache has made a very noticeable difference in VR. Far fewer stutters. I have even been able to crank up my settings a bit more.
So, I think Iām doing this correctly but how do you ensure that you are running OpenXR?
I have the OpenXR app open. And I start MSFS from the desktop which opens Steam, but I presume not Steam VR.
Is there a run preference per program selection somewhere?
Itās a bit academic really. Since the last patch I canāt get MSFS to run well in 2D, much less
3D. 
At the moment itās just a on/off per āstackā for OpenXR. If youāre WMR then it will default to use that unless you change it. If you do change it then starting the WMR Portal app will show a blue bar at the top that asks if you want to change it back to their stack.
If SteamVR/OpenVR then itās a new setting here, which shows the current one being used:
Generally for MSFS, if you have WMR use the Microsoft one, if you have an Index/Vive then use the Valve SteamVR one.
Hmmm, thanks?
Sorry, but you lost me somewhere after, āAtā.
So with a Reverb 2. If I open the OpenXR first,
it will default to that. I didnāt see where in WMR it allowed me to pick one or the other.
Still, my new 3090 runs this like sublogic, so I think that this is not my biggest problem.
I almost canāt find a level of detail low enough to run this sim smoothly over central Jersey. Much less an actual city.
But about 50ft above the water, it runs as
smooth as silk.
Gonna try to roll back drivers. Iām sure that
will work out famously!
Thanks for the help!
Yep, for a Reverb 2 and WMR, if youāve not changed it then youāre good. It will be using the default WMR one.
Some MSFS VR settings tips here - My VR Settings & Tips
For a 3090 I would set in-game Render Scaling to 100 and then use the OpenXR Dev tool to just turn OFF the āCustom render scaleā setting, plus try it with reprojection set to always OFF, although some people like/hate that so a personal thing.
Nvidia drivers and VR seem a mess. Iām still rocking 457.30 but on a 2080, so not sure if it helps the 3XXX line so much. For me it works much better, not in pure fps but just in smoothness.
For the last update (actually since World Update 3 / UK) it seems like the āTerrain Level of Detailā is killing things, so try that at 50 and if ok creep it up to 100 - there seems to be a performance issue with the photogrammetry for a lot of people.
Thanks man! I have actually read every post
in every thread youāve written about the subjectā¦but your magiks havenāt worn off
on me.
Iām getting stuttering over central jersey with graphics set to low end, Online Connectivity set
to off and Roaming Whatever disabled.
Itās a slide show. What makes it more weird is that I just hopped over a ridge to the east of Old Bridge airport and, bam, smooth. Turned around, choppy. Dumped down in a shallow river
valley, smooth. Popped out, choppy.
IL-2, Elite no issues whatsoever. GPU never gets over 80C from what I can tell.
Itās a mystery!
Thanks for the help though.

PS, I hate mysteries. 
EDIT: I should mentionā¦this is all in 2D. On goggles, itās worse!
Oh man, that sounds annoying. 
I know youāve probably tried this, but could be worth a go:
Rename your āCommunityā folder, just to clean out any add-ons.
Reset your scenery cache. Options / General / Data - make sure the cache is āManualā (Rolling Cache set to off) and use the āDelete Rolling Cache Fileā as well - itāll use any old data until itās removed, so maybe a bunch of bad data in that area?
Debugging and support for MSFS on the PC is a bit of a nightmare, as itās a combination of CPU / GPU / Drivers / OS patches / Network Connectivity / plus all their online services for weather/scenery/traffic/voiceATC and then just plain sim bugs - itās basically a test matrix from hell. 
Well, I was looking for a hobby.
I actually had dumped my cache; less because I knew what I was doing and more because I tried all the other buttons.
First.
The launch of DCS 2.7 Beta seemed like a good reason to postpone any DCS plans I had, and finally try MSFS in VR. (I only fly stable release version usually)
Ryzen 5 5600X, GTX 1080Ti here.
Hadnāt flown MSFS since the Christmas holidays, and I had some updates to run. However, at some point during the downloading and unpacking of updates, the sim crashed. I tried everything: Reset/ Repair / Reset again, uninstall, re-install, repair, reset, repair, reset.
Finally (after taking a backup), I decided to just delete the full Packages folder that contains all the stuff MSFS downloads (everything except the 8GB program itself, basically).
Well, that did it. Re-did the basic bindings (stick and rudder, throttle, prop, trim, mixture, flaps, gear), and went flying.
MSFS in VR with this setup is amazing, but still very much an exercise of self-restraint. You simply cannot have high definition clouds, and no jaggies, and readable cockpit, and no stutters over a big city.
In my completely subjective experience, turning down building detail and object detail helped a lot, and allowed me to up the clouds some.
I did it because mountain scenes were already OK but my hometown was causing a big hit on frames, and that is mostly buildings and objects.
Using Samsung Odyssey, I currently switch between 70-80 resolution scaling, TAA on,rest of the settings mostly default except as aforementioned: higher cloud setting, lower buildings and objects. No changes in OpenXR Tool, except setting reprojection to automatic.
@fearlessfrog maybe I should try dialling back terrain detail as well, but I like the orthophotos so much!
Absolutely agree. Because I tend to do tube-liner stuff on MSFS, with so much time up high, then I can just about get away with it in VR, as itās pretty much on the edge of being good.
One thing to pin some hope on is that the Asobo team are currently pretty much 100% dedicated to trying to nail the upcoming Xbox release. From what they said so far, that has been an extreme exercise in optimization and performance improvements. It seems really likely that any core restructuring to make it work well on a console will actually help the PC version as well. I remain optimistic about performance improvements (and from a knock on impact for VR performance as well).
I could go on and on about the last hour I spent with the Aerosoft CRJ in VR trying all kinds of VR settings (in game stuff) and trying to argue with myself over looks versus performance.
It was weird (or not) because I could continue to turn on features and up the details and stuffā¦and did find some great visuals and performanceā¦but on the airfield itself I was getting just the tiniest tiniest perception of rubberbanding. Not gameplay breakingā¦and weirdlyā¦it was smooth rubberbandingā¦not jerky. Just perceptively. If I could squash that with the high details settings I haveā¦Iād be in heaven. It goes away (or at least I think it does) when Iām airborneā¦so it must be a low level texture or rendering or something. I dunnoā¦ Will post some CRJ photos in the āThrough the Lensā topic while my son is at soccer practice in a bitā¦
Can you imagine thaā day when all flightsim VR is like Aerofly?
