ASUS Prime x570-PRO, Ryzen 5 5600X OC @ 4.75GHz, 32 GB RAM OC to 3533MHz, RTX 2080 Super OC 2085MHz and 8900MHz, M.2 SSD WD Black SN850 fueling Rift S. Windows 10 fully updated and patched, KB5001330 removed, Game mode off and on, HAGS on and off. I have tried different nvidia drivers, oculus drivers, different bios versions, limited frame rate on 30 and unlimited frame rate with OTT and/or Oculus debug CLI, all possible combinations that I could have come up with in past two weeks. Game runs the same and utilizes maximum 55% CPU and 75-80% GPU regardless of the settings and It is very interesting how game never uses 100% of GPU nor CPU but the moment you pause the game everything easily hits 100%! I have the same stuttering on low settings and 35% render scaling and in increments all the way to all on ultra and rendering 100%
Currently running ASUS BIOS 3801, Oculus beta v28, NVIDIA 466.11, OTT 0.87.2.0 but I have already tried all possible previous versions.
p.s. Assetto Corsa, Project cars 2 and DCS world are running on my machine with all settings maxed out in VR smooth as the butter
My guess is you are probably CPU limited like nearly everybody around. If you display your CPU usage core by core, and not the average value (your 55%) which mean nothing, you will find one or 2 cores are at 100% and that’s enough to limit your experience. You can check this also by enabling the Debug Mode in Menu and you’ll see the “Limited by Mainframe” sentence more often than “limited by GPU”.
You have to follow guides around here to lower the pressure on CPU, but don’t expect miracle, the sim need a lot of optimization. We have in forum people with latest hardware suffering the same.
I have an I7 10700K OC 4,9Ghz (and tested also OC at 5.1Ghz), and RTX 3070 OC, 32GB, and I’m CPU limited in a lot of scenario, including all airliners but not only. Simpler planes with gauge steam are more resource friendly and you can expect better performance with them.
I can maintain in a lot of situation 45fps ASW OFF with my Oculus Rift CV1 (lower resolution than you), Render Scale at 70% and Oculus pixel density x1,7 with a mix of low, mid, high and ultra settings (mainly for texture). The result is pretty crisp (for a CV1).
So don’t give up, you need some reading, and patience for Devs to optimize!
Try the Cessna 152 in VR, you will see the performance and smoothness increases dramatically.
For the more complex aircraft, the only setting that makes any difference is the rendering scale. So drop that and increase your supersampling using OTT or Oculus debug.
I really appreciate your efforts and I don’t want to sound rude but I don’t think that you have read the whole post. In no scenario I have managed to get 100% on any single core and with lowest and highest settings I have the same performance. I’ve tried with many different monitoring tools qnd overclocking tools…
I also use MSFS + Rift S + 1080Ti + i7 8700K and despite trying all the tips and tricks for a month, I still can’t get rid of cockpit jerking.
FPS and scenery outside the window is OK, but even a slight head movement causes exhausting shaking of the cockpit. Every plane, minimal setup etc.
I think the oculus application is to blame, becauseas I had it, also in X-Plane. Fortunately, I can run X-Plane via SteamVR and the simulation is then perfectly smooth. However, this trick doesn’t work in MSFS.
Coild it be that msfs just doesn’t like oculus? Even though I highly doubt it because there are countless of others that have supersmooth with 30Hz ASW.
I’ll continue testing tomorrow and report back
Other thing that also comes to my mind is that rift s is not supported properly. It is 80Hz and half is 40Hz and that wold be some logical native ASW as for rift cv1 is 45Hz becaus it’s 90Hz device. All of the settings in both ott and OCULUS debug are 45 and 30 Hz… IDK, will have to explore more…
As for me, I have given up hope of being able to smoothly look around in the cockpit with my Rift S and my current computer setup: i7 8700K; 1080Ti, 32RAM (3000).
Nobody will improve the Oculus application anymore for the discontinued Rift S.
All the latest NVidia drivers are mainly aimed at the newer 30 series cards …
And MSFS (Asobo) doesn’t care about VR either.
So I’m waiting for better times to upgrade my hardware to the 3080Ti or 3090 + i9 and then the Reverb G2 (or something better will come in the meantime).
Graphics card prices are currently sick.
So I now fly 98% of the time on my X-Plane polished over the years.
Im running a 3080 and a 5900x on a clean install and can on occasion get a stutter free flight on the quest 2 , but its very hit and miss , perfect one flight , almost unplayable 30 minutes later , i can change settings on the debug to fix things and then find myself switching it back to fix things on the very next flight , doesnt seem to make a great deal of difference whether through steam vr / Link /or air-link though air appears to be slightly more stable
45hz FORCED in OTT translates to 40hz on the Rift S.
Getting ASW off really is important if you aren’t running via SteamVR, ASW just doesn’t work properly with MSFS.
I have seen folks down at 18hz with Steam smoothing and no problems. Prior to the uk update I was able to run 18hz ASW in OTT on a 1660ti, after that update I can’t use ASW at all on a new 3070 5600x build.
I honestly don’t think anyone is running smooth 30hz ASW with the store bought version of the sim and Oculus OpenXR runtime after the UK update.
I have 2 PCs here, a 1660ti and 3080 system and neither of them can have ASW on since that update without the image corrupting terribly. ASW only works correctly if I pause the sim.
I flew Himalaya bush trip with Cessna 208b ad it was the smoothest and best flying experience so far in MSFS and I guess that in some situations it actually is possible to get the smooth performance.
I710700 and GTX1080Ti with Rift S here. My personal cure for the cockpit jerking: HAGS Off + opening apps in the following order: 1) Oculus; 2) put your headset on to fully open the app; 3) MSFS. No OTT, render scale at 100%, settings on medium, textures and clouds on high, AA OFF.
Sorry, as you only said CPU 55% usage I didn’t think you checked per core, my bad.
One of the problem we have monitoring MSFS are the CPU spikes, often due to the instrument display panels. Problem come from the granularity of monitoring tool (often from 0,5 to 2 seconds) which don’t catch a rapid spike so you may think you have E.g. 80% on one core where in fact it maximized to 100%. In scenario where changing any graphical settings (even lowering Renderscale to 30% monitor or VR) your FPS don’t really change are often due to CPU.
I can only maintain my 45fps ASW OFF with plane with steam gauge, and the most FPS friendly plane I use is the Cri-cri where I have 45fps nearly everywhere.
Also, only ASW 1.0 is managed in MSFS and we have a thread to vote to implement ASW 2.0, that will make lower refresh rate more comfortable:
The good thing is MSFS part of Devs said during last Dev Blog they don’t fly on monitor, only in VR, so we have some hope they still optimize the Sim. In any case any optimization on the main engine will benefit for all kind of sessions
Edit : Oh and if you want to really fly at your native headset fps and with supersampling at more than 150% on ultra settings, I suggest Aerofly FS2. I clean my VR eyes with this Sim (and also Asseto Corsa and Automobilista 2)
Thanks for this, I’ll check out that thread. I’m not trying to fly at native res nor FPS, I’d be happy as a baby when it gets favorite candy only if I could fly on 30 FPS.
Regarding testing and all - I could have written few more details. I have monitored with many different tools, even doubted that some of them has influence on performance… I did at least 3 clean rebuilds of windows and 5 of MSFS on different SSDs(so it gets dedicated boot). All of that was too much details because it’s 2021 and almost nobody reads in details. Back in the days of first forums it was different.
