Exactly, this is one of the reasons why I sent my 6900XT back. Shame really, it’s a fantastic card. But it’s poorly optimized for VR. In MSFS and truck simulator I had exactly the same problem. This is such a big con I wouldn’t advice anybody to buy amd gpu’s if you are a VR gamer. ASW only seems to work smooth if you hit max fps with asw disabled, if you then enable ASW it’s smooth.
I got a 3090 now and MSFS is smooth with a 30 fps lock and the g2. Truck simulator is smooth with reprojection on…
It seems there are just few AMD GPU owners with FSMS VR experience. In no other game (No Mans Sky, Dirt, The Room, Project Cars, Accetto) I have a crash or other problems with my 6800XT - only Flight Simulator has problems and so I don’t know if you can say that AMD does not have VR under control when the other games work. I don’t have the performance problem - the graphics card works fine with the HP G2 - but the flight simulator always crashes. I don’t give up hope, but I am a bit envious when I read/hear that there are no problems with VR with the Nividia 3080/3090.
I agree it works, until you can’t hit max fps and you need reprojection or asw. Just try a really heavy VR title where you need these tricks then you notice the problems compared to nvidia. Especially in flightims or racesims where you need a smooth experience.
I also had this stuttery problem when flying over big cities like London, or Paris at low altitude, when I look down. Following your message, I tried to disable ASW with the Oculus CV1. The stuttery is hardly present anymore.
Until now, despite an OC of my RX 6800 XT @ 2650mhz I had been disappointed with its performance.
Yesterday I set the minimum to 2550mhz and the maximum to 2650mhz. I went from 22.5 fps with drops to 19.6 fps on the TBM 930 over London to ~ 30 fps.
With an A320 taking off from KJFK I went from 11.2 fps to 22.5 even increasing the resolution scale to 150%
I am all in Ultra to do his tests.
I think the ASW of the Oculus duplicates an ASW from AMD or MSFS, because even if I turn off the ASW of the Oculus I still have the 45 fps step when it can’t displayed 90 fps and 22.5 fps when it cannot display 45 fps. It can even display 11.2 when it cannot display 22.5. Now it is certain that at 11.2 fps it is not playable.
@ATCCM There was a tire advertisement with the slogan “Without control, power is nothing”
We can not deny that these RX 6800 XT does not lack power, now we just have to hope that AMD comes out of the drivers for us to master this raw power.
I wanted to send it back to the merchant, but when I saw the unavailability of RTX 3080 and the prices of the RTX 3090 I decided to keep it and hope for improvements on the AMD and Asobo side.
EDIT: I just relaunched MSFS without having the OC of the RX 6800 XT I have the same performance.
I realize that I spent at least 90% of the flight time testing with this game …
I just got an HP Reverb G2. Seems amazing to me, but unlike the Oculus CV1 with which I didn’t have smooth landscape movement looking down, with the HP Reverb G2 the scenery is smooth.

I have the same setup as yours. Running 6800XT with G2, and frequent CTDs have been driving me crazy. Driver timeout, d3d11.dll and vcruntime140.dll crashing. After the latest SIM update, instead of crashing to desktop, the VR mirror screen just freeze and my VR headset goes black. I had the 3090 that I bought for retail and sold it for 6800XT hoping to save some money, but what a disaster it’s been. My first G2 would not even turn on with my 6800XT, the replacement unit works well, but now crashes in every flight. I hope this is a fixable issue but both MS/Asobo and AMD have been completely silent despite numerous emails and bug reports. What kind of message do you get in the event viewer after CTD?
Frankly I bought it, thinking I was going to send it back before I even received it, so I only read negative about this G2 starting with the sweet spot. Again, it has nothing to do with what I had imagined. It was a YouTuber who convinced me to test it, and for the moment, I do not regret it. (I cross my fingers and touch wood to keep it going …)
Have you updated the 21.2.3 drivers for the RX 6800 XT?
Before installing WMR I ran a Windows update.
Hi Beulah6126 - what is CTD? Sorry for asking.
I did a step backwards and installed 20.11.2 AMD drivers. I didn’t test it with VR, but I remember, that the first installation with this drivers runs best. But not sure. With the lastest 21.2.3 it was a nightmare, but the version before run best, but had a lot of crashes as well. So I will check it. I do never get and error you described, just FSMS close - that’s all and AMD software informed be about a crash. In G2 the screen is freezing, but the sound is normal. Next time, I will notice and post it here.
J’ai trouvé: Crash to Desktop (CTD)
Alors, je n’en ai jamais eu depuis que je joue à MSFS que ce soit avec la GTX 1080 TI + le CV1, ni avec la RX 6800 XT + CV1. Je verrais bien avec le temps si j’en ai avec la RX 6800 XT avec le G2
A short interim report. The driver 20.11.2 does not work, because the G2 needs a newer version. Have therefore 21.2.2, since I had the best experience with it. Yesterday I had only after 20 min. before crash that the computer simply performs a reboot. Even with the latest update of MSFS 1.14.5.0 improved nothing in the situation. Fatal crashes with the AMD graphics card. Since users 3080/3090 do not have such problems, I now fix assume that this is due to AMD. I bought Anno 1800 last week and there too are massive problems that the PC simply restarts in the game. In retrospect, it was the wrong decision to buy the 6800XT.
Did I read that correctly, you have no problem with the Oculus , but with the G2 your system crashes?
I paid 840 € for my 6800XT, so it’s certainly a win when I look at the prices now.
What I am currently trying out besides all the actions to launch MSFS via SteamVR. It stutters pretty well, but I’m interested to see if it also comes to such massive crashes as well.
I don’t have a Reverb G2 (yet) but how do you guys connect the USB of the Reverb? Through the graphics card or through a motherboard USB port? I’m asking because I read somewhere (can’t find the link anymore) that the crashes might be a problem of the GPU hitting it’s power limit. This could be exagerated when connecting the headset through the USB port on the graphics card. The fact that you guys see reboots of the whole system supports this theory. As I said. I don’t own a Reverb G2 yet, but I’m thinking about it. And I’m on a 6900 XT which performs excellent in 2D in MSFS.
That’s right, since the release of a version compatible with VR, with my Oculus Rift CV1 (Fortunately I still have it) until Monday or Tuesday, when I received the HP G2, I never had a crash in VR. I had MSFS shutdowns while loading, but in 2D. But once in flight in VR, I never had all this feedback on the desktop, with an AMD alert message.
I still have my GTX 1080 TI. I will reassemble it, so we will know if these crashes with the HP G2 are due to AMD GPUs or to an always AMD motherboard problem.
Besides to make things right, like I said on this topic there are 50 subjects, which talk about the same problem.
If we add to that, all the people who post messages because they have questions, or any problems, but who never specify their PC configuration, their VR headset model, or with which plane, or where, nor with what settings.
I have known forums devoted to video games, where a signature with its PC configuration was mandatory, or strongly recommended, because it allows you to know what you are talking about.
In our case, with the HP Reverb G2 crashes, we could have known, if the problem came from AMD GPUs, like the 6000 series, maybe also the 5000 series.
According to [AMD] (MSFS 2020 Crash in VR - HP Reverb G2 - #25 by bstange2306), the problem would come from X570 motherboards with VR headsets, except that at home the Oculus CV works very well with my X570 motherboard and my RX 6800 XT
First, Flight Simulator would crash to desktop just after a few minutes of playing in VR mode. But then I found a way to fix the crashes by setting TdrDelay in the registry as described in some reddit post.
However, the VR experience with my setup is horrible.
Already in the menu I see the wobbling effect that has been mentioned before by other users in this thread. The grid that is displayed in the main menu at the floor and the ceiling is constantly wobbling, and when I look to the sides or down when flying, the whole scenery is wobbling / stuttering. I’ve tried multiple things like disabling / enabling motion reprojection etc. but none of it improved anything.
Has anyone found out anything new how this can be fixed?
It definitely seems to be an issue with AMD graphics cards.
A friend of mine who is using a ryzen 3950X with an rx6900XT has exactly the same issue.
I have an RX 6800 XT with a Ryzen 5 3600 and 32GB of 3200MHz ram.
I have no problem looking down at the ground, even when flying over a city like London.
Are you using the SteamVR or OpenXR runtime?
And what are your graphics settings in the game?
I’ve tried both WMR and SteamVR runtime, didn’t make any difference, and also tried almost all possible graphics settings from low to ultra, all anti aliasing settings - none of these changes make any difference with regard to the strange wobbling effect.
Type “regedit” (without quotes) and press Enter. This will launch the registry editor.
Find the following key: HKEY_LOCAL_MACHINE / SOFTWARE / Khronos OpenXR / 1
Do you have that address?
C: WINDOWS system32 MixedRealityRuntime.json
Or
C: \ Program Files (x86) Steam \ steamapps \ SteamVR \ steamvr_win64.json
I also want to add my disappointment, also with the hope to find a solution with all the other people here.
I am using the oculus_openxr_64.json runtime (Quest 2) and tested the many different suggestions with my old 2060 super and the new 6700xt that I luckily got for the OVP. I would rather say the performance is worse than better. I have more wobblings until I completely disable ASW via Debug Tool. Still the performance appears worse compared to the 2060s. I might give the SteamVR a try but I doubt this will produce any difference after what I’ve read here. It would be interesting if some additional settings within the AMD Radeon Software would make any differences. For NVIDIA there are some suggestions, wonder if they work with AMD.
