Poor performance with my new gaming pc and msfs 40th edition

User Support Hub Virtual Reality (VR)

Hello everybody,

I have recently brought a new gaming pc, but I have found that MSFS 40th anniversary ·lags· (let me explain it later) too much IN VR with a Quest 2 headset, contrary to all the other games that run smoothly; Here are my specs:

AMD Ryzen 7 5800X

Sapphire Radeon RX 6700 XT 12 GB

Ram: Vengeance LPX DDR4 2X16 GB at 3200 MHz

SSD: XrayDisk M.2 flash TLC

I connect the quest 2 via wifi 5GHz to a router that’s NEXT TO ME, With a 1 GB symmetric connection to the internet, and using the Virtual Desktop app from the Oculus Store.

In Adrenalin 23.12.1, I have set Global experience to “Performance”

I have set SteamVR as the current OpenXR Runtime

In MSFS, I have set the Global Rendering quality to “High-end” @1920x1200,TAA, render scaling 100, AMD FIDELITYFX SHARPENING 100, v-sync OFF, DX11

In the Quest 2, I have enabled the 120 mhz Refresh Rate

Then, I choose Activities, Discovery Flights, NAPLES (Italy)

If I look at the front, it’s acceptable, but when I turn my head to left and right, everything stutters a lot (specially nearer houses/towers, etc.), like… things like a house, are on one place and 10 ms later they move just a little bit ‘backwards’, I don’t know how to explain it clearer.

I have tried also to use Oculus air link instead: In the windows Oculus application, I have set the OculusXR runtime to this application instead of SteamVR, but the result is the same with that stuttering, and the image looks horribly pixelated without changing the resolution!

If I disable in data the photogrammetry it also happens, even with everything offline.

Even in low settings I have some stuttering.

I am very, very frustrated with this situation; One of my biggest desire was to be able to play MSFS in good conditions with my new gaming pc, not this !

Any help to optimize my configuration would be very appreciated, this can’t be normal !

Best regards

Switch the runtime in Virtual Desktop to VXDR and make sure SteamVR and Oculus app are not running. That should improve things significantly.

Thanks, but I have not noticed any improvements… The only way to play with minimal comfort is choosing the medium specs… I thought that my new pc would be able to handle this more easily… Such a dissapointment

This sim requires a NASA mainframe, my god !

I know EXACTLY what you mean, and I have had this EXACT behaviour (using Virtual Desktop) that I have been trying to fix all weekend. I just got a Quest 3 this weekend (well, earlier in the week but not had time to dig into it properly until weekend) and spent all weekend tweaking and trying everything I could to get it smooth. Finally, at 5am on Sunday night (I guess you could call that Monday morning lol) I found the golden ticket. I hope it is the same for you! Let me explain.

GPU driver!!! I thought, stupidly (?!) that having the NEWEST driver (I am on Nvidia RTX4080 but this could be for you too) would be best so I installed that before trying for the first time. After MUCH research and advice from various people, I tried an older driver and instantly it was all perfect.

I don’t know about Radeon cards so not really sure if this will help you but it is worth a try!

Also, I would NOT use 120Hz… that means it’s PUSHING your sim to provide 120fps!! Not going to happen, as it really means 240 (120 for each “eye”). Turn that down to 72!

Are you using the Spacewarp? I turned that off. I also PREFER DLSS with DLAA (or Balanced) setting, and using High in VD. But these don’t seem to make a huge difference to frame rate so it’s personal preference. I just think TAA even at 100 and with Sharpening looks too rough. DLSS is softer yes, but looks more natural to me. Still I can read cockpit dials fonts so that is fine for me. Glass cockpits are harder to read but I can accept that.

I would also be happy with lower in game graphics settings - you can’t really run Ultra and expect it to render everything TWICE smoothly when it is on the verge of coping just on flatscreen so please do compromise there. Turn down LOD’s (under 100 each) and DON’T use Ultra volumetric clouds. Try MEDIUM preset then turn a few things up slowly 1 by 1.

FYI I use the wifi 5ghz too and that is not the bottleneck. There are a lot of settings all over the place and it’s very sensitive to all of them but you will hopefully find it kick into gear with this advice (mainly GPU DRIVERS!).

For sure as PacyFire said use the VDXR protocol and TRY the HVEC option as well as the other ones (I use AV1 but that is only available on Quest 3 I think).

Hi,

Sorry to hear you haven’t had a good experience yet. I’m currently using a Quest 2 and it took me a little while to find the best settings.

My PC is/was fairly similar in configuration. I’m still using an i7-10700K and up until recently was using an RTX3070 for 1.5 years (not long upgraded to an RTX 4090).

I’m away from my PC at the moment but happy to share what worked for me with my 3070 to get smooth performance.

In the meantime, try switching to 80Hz mode in Oculus runtime, setting the resolution to 1.2 or 1.3 thereabouts in Oculus, and in the Oculus Debug Tool change ASW mode to: Force 45Hz ASW enabled. If using airlink be sure to leave the encode bitrate at 0, otherwise it will stutter.

If that’s better, we can then try improving things with better resolution, openxr toolkit, virtual desktop (if you have it), DLSS etc. Note: smoothness at times may depend on the type of plane you’re flying and location.

With my current setup and the 4090, I use virtual desktop, DLSS quality, and an openxr toolkit override resolution @ 4250 and 90Hz. It’s very sharp and smooth.

Cheers

Which driver are you using?

535.98

I tried even older first (someone suggested 531.29 as the best) but MSFS said this on startup:

Tried anyway with 531.29 and no different but I had the 535.98 (I think… not at my PC but .9 something) on my disk already (one I have used before) so gave that a shot instead — lo and behold it was fantastic!

Disclaimer: did 3 test flights including low and fast through New York (fluid!) then shut PC down and not tried again since, so I hope things are the same next time I’m on!

Thanks everybody to all the excellent advice !

I can advance that I had made some improvements, but there is such a complexity that in fact it almost requires a full time job to nail it !

I will test all your advices (and much more) asap, and I will return with the info.
