HOLY SH1T! I cannot thank you enough! I fought with this thing for days and someone on a Reddit mentioned this thread!! It worked!!!

Hereās to hoping that one of these days, NVidia gets around to writing a driver that specifically targets VR in FS2020. You know they gotta be working on one! But Iām impatient, and I want it NOW!! LOLā¦
But smartassery aside, I do think it could make a huge difference in our experiences with this sim. As much as going out and buying a whole new GPU could, evenā¦

I have the NVIDIA Experience downloaded and installed.
It ensures you have Game Ready Drivers and and it adjust the card for diffferent games. I only have the MSFS installed in it and I get 60+ on a modest system set at Ultra.
You can see my setup in my profile.
I think the NVIDIA Experience knows how to optimize the GPU to get the best Performance and uses other drivers.
Tomorrow, I mean later today, I will do some screen shots of it.
I know I have different drivers that what other NVIDIA owners have. Already in bed and using my iPad, but I will post all that later.
I do great on an RTX 2060 Super which is not a top end GPU. More like a middle of the road GPU.
The settings offered by nVidia experience are pretty bad/low and even worse for VR. The settings offered by the OP are way, way, way better.

You might want to read my comments about GEF auto settings and why you should never use it for FS2020: Table of NVidia Drivers release notes highlights from 446.14 to 461.09
Then read the additional bloatware installed along with it in newer drivers and being a root cause of some of the stuttering: What NVidia Drivers are recommended for VR
This performance issues are very problematic and systems way better than mine are having problems.
I have GEF installed, run on ULTRA and can get 60FPS pretty much anywhere. Name the worse place you can imagine and I will show you that I can get 60FPS. GEF doesnāt have any negative impact in my system that I have noticed. I use the FrameRate overlay from GEF.
I see people with I9 CPUs and RTX 3090 GPU complaining that they go down to 7 or 10FPS in large cities or complex airports. It makes no sense. Iām on Driver Version 461.40. Only add-ons I have are about a dozen airports bought from Market Place. I had the London Pack and deleted it when I installed UK.
This is my configuration.
Dell XPS 8940

Sorry, no not in VR. I probably shouldnāt commented on this thread since it is indeed a VR thread.

ok - mystery solved then

Iām glad you manage to get this perf on your system. This might show the Intel single core performance of the 10700 is a defining criteria for fps with FS2020. Besides, single-core performance is usually a requirement with most simulators except maybe XP11 which is implementing a very sophisticated and fined tuned work task scheduler*
Having said this, with a 9700K @4.6Ghz + 2070S, I can largely get 60fps as well in 1K, but not as much in 4K. You might want to review this detail when someone is saying their fps are dropping when comparing your system.
Nevertheless, just to reference the material in this topic too, here is what Iām saying about GEF to make it clear:
*I believe the necessity of supporting Linux, macOs and Windows are compelling reasons to build your own instead of relying of the OS provided per-app thread pool and this definitely gives an advantage to XP11 for this matter:

I donāt know if FS2020 is implementing their own or if they are using the OS provided ones only:

With me, if you leave VR mode, before you go back in you need to shut down WMR and let the frames stabilize in pancake mode in MSFS because you go back into VR and let WMR boot back up again.
Things are a lot better now that the patch fix was released (or at least i think this is why) and my windows install isnt borked. However, i still do have issues going in and out, sometimes even if i close wmr after exiting vr, turn it back on then enter vr its a messā¦ or ill exit vr and 2d is literally 5 fps.
Yea, thereās something weird going on with the switch and I hope they figure it out ā would really like to VR for departure and approach but pancake for cruise.
Iām wondering if theyāre not flushing out the mem allocation for the āother 3d environmentā when it flips over or something along those lines ā itās a really confusing issue.

If you want to save WMR resources you can try these:
Set to 0
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Holographic\PreallocateVirtualMonitors
This prevents WMR to reserve VRAM and resources for popup windows youāre opening in VR. If you donāt use any, you can save some with this.
Set to 1
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\HoloSI\DisableShellUI
This deactivates WMR Portal Software with a few caveats to know:
https://www.reddit.com/r/WindowsMR/comments/l9irdw/how_to_deactive_wmr_home_completely_registry_key/
NB: these are all REG_DWORD
Nice! Iāve already disabled virtual monitor preallocation from the DCS days. For now I think I want to keep the portal software but thatās a great trick.
I shall add, and it is not another disgruntled CptLucky8 post complaining about the G2 and praising the Index, but switching back and forth VR mode with SteamVR has been painless for the last few 1.16.x versions.
Yep, Iām stuck with the G2 though.
@CptLucky8, I still havenāt even figured out how to use SteamVR with MSFS in the first place (or even why I would want to), so disabling WMR would likely not be at all helpful to me lol!!
It is not disabling WMR, it is disabling WMR Portal, the thing which shows a 3D house in the headset prior launching the game. The registry key (with some caveats - read the reddit comments - ) is disabling the house in order to skip loading 3D assets and resources for nothing.
Hi, So, render scale at 70% in MSFS after this recent update is horrendous. Blue outlines all over the place and flickering image. So, I tried 100% in sim and then 70% in OXR. This then reduced my sweet spot quite a lot, so I did not like that.
So, out of curiosity, I just left open XR at all defaults, and set the sim render scale at 100%.
I am running a 3090 . I thought it might have auto adjusted the resolution down ( I kept checking), but it didnāt. I added some clouds, night time etcā¦ day time. Stress tested it.
Man, why was I messing all this time?! 100 render scale in openXR and in sim is so sharp! The sweetspot blends so much better! And the performance is WAY better than I expected it would be. Its actually really smooth too! I think I will just leave it like this now, its what the G2 was designed for!, and let them craic on with optimizing MSFS.
PS This is with an i9900KS at 5GHZ and also using high refresh rate in cockpit with the Beechcraft bonanza glass cockpit.
