10FPS with RTX 3080 in VR with Reverb G2. Solutions?

Again, leaps and bounds better, not sure how else I should put it. Absolutely game changer (literally).

I agree !

Just tried with rift s so smooth with old nvidia pilot but 10 fps less… so strange ! Lol

But verry better than with last pilot

Now i will try with reverb G2

So I had the same issue:
3080, 9900k, 32gb ram, quest 2, latest nvidia drivers.

this happens to me when I start the game from steamVR, so what I did that works all the time:

  1. Close SteamVR, (keep your headset connected)
  2. Launch FS2020 from steam (non vr)
  3. After it load the menu in non VR mode, activate VR (CTRL+TAB)

and thats it, it goes from 10-15 fps, to 50-55 on low-off graphic settings, still the performance is really bad, but at least is not a slideshow. Hope they fix it soon

I confirm it’s the pilot 457.3 which run better !

Unfortunately the 1080ti is not enough :frowning:

But now i know that is the last pilot the problem

The experience literally changed !

With the rift s its perfect !

Now waiting to the release of the rtx3090

When my G2 arrived I have not been able to fly DCS and I wondered why it was so slow and laggy.

I searched the web and found a solution that helped a lot:

I found that Steam VR seems to have a faulty standard setting concerning the render resolution for the HP Reverb G2.
The system sets render resolution to AUTO, but 100% of render resolution is far beyond the natural resolution of the head set (2160 x 2160). Using Render resolution values that are close to the natural resolution (in my case 48%) solves the issue and DCS starts in VR mode and everything is fine.

Maybe you would like to try this aspect (if you didn’t do so yet) …

Look also at:

On the contrary, Steam VR is using the exact optimal resolution for the G2 (see Peter Peterson’s comments):

WMR Scaling and Dev Tools - Some Explanations

But I agree this is a massive amount of pixels to push!

I have ~10 fps on 1080ti and samsung oddyssey+. Unplayable. 8700k. Even with low, potato graphics, unplayable.

How does amd’s 6800xt run this in vr?

Im having the same problems, RTX 3080, 9900k, 32gb, and a HP reverb G1, i get ± 30 FPS but a lot of stutter, rolling back to 457.30 helps but isn’t a game changer.

I would be more then happy to give up some clarity for more fps but whatever settings i use it always the same, even on ultra with 100% render scaling 28fps (but stutter).

I really hope they update there drivers so we can all enjoy this very nice sim

I’ve got an RTX 3080 too and it seems pretty clear the new RTX 3000 series cards are not well optimised for VR at the moment. Hopefully Nvidia will get that sorted out soon.

The sim itself is obviously still in its early days of VR. Its pretty much still in an open beta phase. Sometimes I start the sim up in VR and get almost perfect performance, steady high FPS with most settings on ultra. Yet sometimes I can boot up the sim with no change to any of my settings and its all gone to a bit of a mess with visual artifacts everywhere and a really annoying stuttering.

Its that sort of instability I think Asobo will iron out over the coming months I hope.


Hi Mobias,

May i ask how many FPS you are getting in a good session?

Hi @CptLucky8 the barrel distortion when rendering at native resolution has never been obvious or a problem for me, I would be interested to know if you have seen this effect running at native resolution on the G2 or any other headset.

So given that, your use of ‘optimal’ here is related to picture quality, thats fair enough. Anything past 50% for the G2 and you are still supersampling right and therefore you’ll have deminishing returns for picture quality against performance.

I only ask as I’ve seen many youtubers explain barrel distortion and give there reasons why you need to run at 100% resolution in Steam therefore making the rest of us look bad (for running at native resolution) and I just feel this is the wrong message to give if you have a G2 which already asks a lot of your system anyway.

I would say on average I get about 25 FPS. Render scale on 100 most other settings on ultra or high. I was just enjoying a flight through the Alps there in the MB-339 at quite low level and it does look amazing but there is just a very slight stutter for me. I’m missing a frame somewhere. Like I said in my earlier post the stutter seems to oddly come and go. Yesterday I was playing and it was really smooth. More often than not though I do get that stutter.

I’d suggest you have a look at Alex Vlachos videos I’ve posted near the end of this post:

My 2070 SUPER VR settings and suggestion (Reverb G2 - WMR)

It will explain things better!

TL;DR: because the VR driver must distort the image with barrel distortion to compensate for the lenses pincushion distortion, you have to render at a sufficient resolution so that the rendered image resolution as enough pixels at its center to fully represent each of the distorted image pixels. With the G2 resolution you shouldn’t notice much difference it you’re using a resolution a little bit lower than 100% (1.5x native res) but you might start noticing more aliasing artifacts at 50% (1.0x native res though).

Fps in fs2020 varies so much in vr. In sims such as xplane it is fairly consistent no matter what aircraft etc. Super dissapointing, also I seem to get low cpu and gpu usage with my i7 9700k and rtx2080ti.

Let’s hope they will finetune everything a bit more like they did with x-plane. I just can’t go back to x-plane it feels so 20’s :wink:


Not optimized for VR? Not really. This is a MSFS problem I think - the MSFS is not optimized for VR, not the 3000 series. My 3080 is absolutely stellar in the most graphically intense VR game: Half-Life Alyx. In the G2 graphics and mesh detail is stunning. It really is. I’m playing through the whole game again after completing it last March in Rift S. And I’ve never replayed a game in my life. IT’s jaw-dropping stunning. Butter-smooth, no stutter at all, all settings on Ultra.

Medal of Honor also plays well. There are many people complaining online about that game being impossible to run smoothly. It does have some problems sometimes, but in the actual gameplay it’s very smooth. So, while the drivers can of course be optimized more, I believe it’s the MSFS itself that is at fault here, most likely. Considering Asobo did not bother implementing VR controllers at all, putting MSFS behind competing sims, they must have rushed VR release to have people play VR before Chrismas. Which was a good idea in general, but they need to finish the job, optimize the performance and implement VR controllers. And also work with Nvidia on VR optimization with drivers.


That’s precisely because the software is rendering a distorted image to compensate for that. In every game or app for VR. Basically it has to render higher-res image for the center of the image to remain sharp after the necessary distortion correction. It almost begs to have some algorithm that wouldn’t make it necessary, rendering only the pixels that need to be rendered (kinda like DLSS maybe?) but I don’t know about about that to speculate further. The fact is it’s a massive amount of pixels to get G2 to remain at full resolution.

Yeah fair points. I only got my headset recently, and my 3080 for that matter, so haven’t ventured much into other games yet. Hope Asobo get things a bit better optimised soon.

I just tried the non g1000 aircraft like the 152 and i am getting a whopping 60fps in the air and 45 on the ground. Never expected such kind of difference

What kind of settings are you using?
