I want to share with you a problem that I can’t get rid of, I always fly in virtual reality, when I look at the horizon through the front windshield the image is fluid and smooth, but when I look through the side windows it is aircraft (Cessna 152) towards the ground, I see the terrain go by jerkily, in jumps, as if my computer could not handle the workload.
Yesterday I installed the wonderful Nis Scaler Beta Hotfix tool and have gained overall performance (Nis Scaler at 80%=2694x2694 and Sharpness at 50%), but when I look out the side windows at the ground, I still see choppy images.
My configuration in SteamVr in general video resolution is 100% and it gives me a resolution of 3368x3368 (Htc Vive Pro 2). I have the latest Nvidia drivers installed (511), I have updated W10 and my computer is not so badly powered.
I need to enable/disable some feature within Steamvr or within the Htc Vive console ???, this is a small program that you dock and paste into the Steamvr window.
I have seen that in Steamvr I have the advanced supersampling filtering option activated, what is this for ???, can it be the cause of my problem ???
I am desperate, I can not look at the ground through the doors of the aircraft without seeing the world pass before me in jumps and jerks. Any help please???
There’s a coupe of things you could check. Go into windows settings and the display and see how many displays are showing up, if it’s not than three then you need to disable the extra vr displays. Windows sometimes sees 2 extra displays instead of the 1 monitor and two vr displays. A youtube channel run by Holdenriot has a great tutorial on that. The video is primarily for wmr users but a few friends have said it helped them out with occulus rift and htc headsets. (Edit: link further down)
You can also try disabling wmr clifftop house; again holdenriot has a good video on that. (Edit: link further down)
Super sampling I believe is for providing greater clarity in VR for those that have hmd with a lower resolutuon. It makes reading instruments a helluva lot easier. If you look up vr flight sim guy on you tube, he has loads of videos on optimising vr for msfs 2020. They’ve helped me out a lot over the past year or so.
Good luck and clear skies!
To get smooth movement out the side windows, you will have to use Asynchonous Space Warp (frame interpolation - motion reprojection) at a rate that is a downsample of your HMD refresh rate. (for example, if HMD is at 90Hz, then downsample rates of one-half or one-third are 45 and 30Hz). Each HMD system has a different way of setup for this. One you see that you are “locked in” to one of these rates in VR (I like using the Shift-Z app from flightsim.to to see it ), your sidewindow viewing will be much better.
I think you should start with aiming at 1800x1800 in NIS.
I also tried everything on higher resolutions to get rid of the stutters on the side.
Also your aircraft makes a huge difference.
I’m getting fluid motion with the Vertigo from GotGravel.
These are my settings with a 3080ti
During flight when I’m at higher altitudes I sometimes increase the OTT DSS to 1.5 or even 2.0 depending on scenery etc.
After changing stuff I always save OTT and toggle Ctrl+Tab to make changes effective.
I am on a 11th gen i9, 64GB RAM, 3080ti, SDD, Quest 2 and get the juddery effect to the side view when flying low.
As others have suggested I put this down to the fact that the lower FPS of the sim due to CPU bottlenecks means this is what you will get. Motion Reprojection is only going to be able to do so much as that is about interpolating frames - at low altitude and speed the jumps from frame to frame are too great.
That said, I do get a very marked improvement at 120hz - not a solution but overall it is enough for me given there are no other tuning options.
Perhaps if Asobo can improve on the sim’s threading, the FPS can be boosted significantly. On my set up only 2 of the physical cores (4 logical threads) are being taxed - leaving 6 cores available for extra load. From experience, though, getting threading right is a nightmare and not all processes lend themselves to extensive threading anyway.
If you use a tool like CapFrameX you will see CPU threads spiking to the ceiling, whereas that doesn’t always show up in Task Manager unless things are completely maxed out - typical overall CPU for me is less than 50%, and that’s with the sim threads spiking. CapFrameX will also show degree of stuttering and frame time variances. For MSFS it is not pretty even at moderate settings.
Using that tool I found LOD to be a major factor as others have said. I have this set to 100 most of the time. More generally, I have the Oculus app res set to maximum and use MSFS renderscale to adjust - typically between 70 and 100. I cap my FPS at 32 (still experimenting) to get more consistent frame times.
Running at the quest at 120hz adds a little CPU for me (around 5%) but the real killer with that is that it drains the Quest’s battery quickly and being tethered doesnt seem to help.
I have the 3080Ti with the G2, and I turn off all aliasing, filtering, sharpening, superscaling, and scaling. I run full resolution with motion repro Automatic. I set my texture resolution to LOW, and and my LOD’s below 100 (T75, O45). I use Bing maps but no photogrammetry. No AI’s at all.
The goal here is to get as close to the original frame as you can without asking for upgrades like Ambient Occlusion, shadows, or filtering. You want the smallest, untouched frames going as fast as they can through the GPU. If you can get this setup going without stutters, then you can work the other settings back into the mix. I have not been able to put my finger on the stuttering cause, but this approach seems to eliminate it.
Good morning friends, I have given you all a like for the help you offer me and for your interesting comments, thank you very much indeed, I have been very disconnected these weeks due to a large volume of work, now I return again to my attempt to remove myself the ■■■■ shuttering looking at the ground through the side window of my Cessna 152.
I am going to try all the advice you give me to see if I can do it, it is very frustrating to have an RTX 3090 and a 8700k delid oc 4.7 with 32 ram and not be able to drive properly.
I have also read on the internet a trick that consists of creating a direct access to the *.exe file of fs2020 and in properties add the sum of cores and threads of our cpu subtracting two units, it would be as follows as an example: --num_workers=‘10’
When you tell me to lower the LOD option within the graphic menu of Fs2020, what option are you referring to?
My language is not English and the LOD option cannot be located in the menu.
Terrain and Object “Level of Detail” (LOD). I always drag them down to 10 for testing so I can eliminate that variable. I have been testing the Beta this weekend, and I cannot get the small ground stutter to disappear. I believe it is a HP G2 issue. Otherwise, my G2 works very well.
Thanks for your advice friend. WARNING!!!: the stuttering on the ground IS NOT UNIQUE to Hp G2, I have installed a new ssd from scratch exactly in the same pc, in this case without WMR and without HP G2, these tests have been with Steamvr and his Vive console and with the Vive Pro 2 hmd and the stutter is still there, oh my god, what a mess !!!.
Impossible to look at the ground through the window.
Any suggestion, dear community, of what to do?
Lowering the terrain and object LOD to 10 softens it, but doesn’t completely remove it.
My setup is I7 8700k delid oc 4.7ghz, 32 ram, Asus Strix Rtx 3090 oc edition, Ssd 1 Tb.
I’ve had these judders and jaggies in my G2 for the past 16 months now. Nothing but nothing could fix this. I was burnt out.
i7 10700, 3080. I came to the conclusion last week that it was my CPU. Bottlenecking and redlining. I just replaced it today with a 12th gen i9 12900. Needed a new MB and cooler. $$$$ Tonight was the first time I have ever flown in MSFS judder-free and smooth as silk through Manhattan and LA! 36fps right through those skyscrapers.
Its an unbelievable difference, I’m just elated!
I’m sorry to say it wasn’t the headset, the NCP, NIS, WMR or game settings after all.
I’m afraid that any older generation CPU’s are going to cause continuous aggravation, that’s the issue here. Gotta stop wasting time tweaking till the cows come home.
what you tell me friend is very bad for my wallet, hahaha. I understand from your experience that putting my Rtx3090oc instead of my current I7 8700k up to an I9 12900Ks with a new motherboard and memories, I will obtain a significant difference in performance ???.
I would like to be able to try an I9 12900ks with the rtx 3090 and see what difference I get and see if it is worth the €1500 outlay for a new pc, the problem is asking an online store for a pc in parts and then wanting to return it if I am not convinced by the frame gain in FS2020, in my country a custom-made PC does not let you return it.
On the other hand, I am not interested in buying a branded PC already assembled, Hp, Asus, Msi, etc, in this case I have 15 days of trial, but I have two problems, I already have the graphics card and the prices of these brands are absolutely outrageous , €3,000 and €4,000 towers, oh my god.
On the other hand, it is not the smartest time to completely renew my pc except the rtx 3090, in September is the launch of the intel Raptor Lake S I9 13900k. With these cpus in sight, I’ll stick with nis scaler, fsr and foveated rendering in vr.
This is completely as expected. Does anyone here do some math?
If you lock sidewards you see the maximum of geometry shift per frame. This is the same effekt you have in a car f.e. Looking forward everything is nice and clear, looking sideways everything becomes blurred, the more the faster you drive - or fly. Approaching at 140 knots means that each object in an 90 degrees angle sideways seen shifts by about 72m per second. For the usual 30fps we can get with the best gpu‘s today this means a 2.4m shift per frame. The rest is done by viewing angles and correlated effects. To become an comfortable feeling 45 to 50fps are recommended as a minimum. Note that even then the foreground will become blurred sooner or later because your brain can’t follow infinitely.
Not sure which headset you use: Vive or G2.
If G2 - you should not use SteamVR, but native WMR OpenXR.
Make sure your config is not impacted by some dependencies of 2 headsets, if you have both of them configured.
With your setup you should be able to have at least 20-30 FPS (assuming reasonable settings). When looking sideways such FPS should give not perfect, but acceptable fluidity of the movement.
There is a great post by @CptLucky8 on the forums how to setup the nVidia and the sim for G2. In fact the original post was removed by the author but it was restored later in the same thread.
Its not a matter of ya wanna see how an i9 will work with your 3090 lol! It will 100% improve your system and experience. An i7 10th gen is a huge mismatch for a 3090! You’ll always be totally bottlenecked at your cpu. No tweaks will ever fix your issues. I know its a costly upgrade, but necessary if you want to stop spinning your wheels. Why do you have a top end gpu and a bottom end cpu?
I totally understand what you mean on this topic, and i have also tried all different options possible to eliminate this issue but only way is to use ASW which doesn’t work in my case which causes odd screen flickering and texture tearings. I have tried 72/80/90hz but nothing worked so far. Even with low-med settings ground is stuttery somehow… I don’t have the same issue in DCS which is buttery smooth.
