VR Stuttering when turning. Any suggestions?

[Devil in me.]

First off, I can never go back to playing on a flat screen, VR is so immersive.

I am running latest version of Steam VR, the beta and all drivers up to date.
Tried on Valve index and Meta Quest 3 with steam link.

System
Rtx 2080ti
i9k
fast ssd
32 gig ram
windows 10

The game runs ok, and I have done the usual,
set to 60 htz
scale 100
and the pathelora of other settings people suggest.

My main issue is when looking out of either of the windows or when turning it stutters so bad it makes me feel ill, in fact i find on steep bends or turning in a yard i close my eyes its that bad. Any suggestions on what i can do to stop with stuttering, its like in stead of 60fps its only showing say 20 frames. Its fine when in a straight line, but anything that moves across me forward judders and stutters.

It ruins the experience. I have tried openxr but it changes nothing. hoping it might be a setting somewhere as I really love the vr experience just needs finessing.

Thanks in advance.

The game stutters immensely when turning regardless of VR or not.
The game has massive FPS drops in the updated areas.
ATS is especially bad compared to ETS2.
Try lowering mirror distance and quality.

Yeah I don't have any of those problems.

Stop talking rubbish, any problems YOU are having are self-inflicted and not helping OP. Are there tens of thousands on ATS players all saying the same thing on here? NO.
Just to emphasise how little you grasp the situation: ATS and ETS2 use the identical Prism game engine, written by SCS just for their games. Identical.

The VR branch is not a fully supported version of the game, it is maintained and updated by an SCS employee, but it is his own project. Updating it always lags behind the main game by some amount.
If no-one can help here try the official SCS forum as well. I am not a VR user and have no insights to offer, but careful attention to all the GFX controls in the chain is essential.
There are now so many different programs involved in game GFX you need to look at all of them, the VR program and drivers, the Nvidia drivers and Nvidia control panel, Nvidia GeForce Experience, Windows game settings and of course the game settings themselves. Altering any of these can cause problems or fix them.

General points to also consider:
If you've previously used the TAA graphics mod, delete all files from it.
Make sure the game and Steam are not running in compatibility mode.
Make sure your Windows swap file is set to 'system managed'
Disable the NVIDIA overlay
Disable the Discord overlay
Disable the Steam overlay.
Do not have any programs running tin the background, especially Discord, browsers, Internet chat or messaging.
Reduce any scaling back to 100%
You may need more than 20GB free on the system drive for swap files
If you are on NVIDIA and have previously used the Profile Inspector for better anti-aliasing, all SCS profiles MUST be restored to driver default, for game version 1.50.
If you use DSR, deactivate it.
Clean all system fans, make sure all grilles are free from dust and the cooling works properly for the system, the PSU, the GPU and CPU.
Always make sure your graphics drivers and Windows are both fully up to date.

That's interesting, how would the logs help showing what causes FPS loss or spikes?

i would try disabling hyper-threading in bios, usually stops the stuttering.

if disabling hyper-threading does no good , iwould point you to a modder on trucky that has a mod that may help........hope this helps.

I run Quest 2 linked to desktop PC (2070 RTX, 9th gen i5 OC 4.3 GHz). In addition to most of what was mentioned I use the Oculus Debug Tool to Force 45 fps with ASW enabled. I've turned off all in-game anti-aliasing. I've also limited my mods to as few as I can tolerate (7) and I run smooth as butter.

I used to do this with my quest 2/1080ti. Basically, you are getting a smoother lower frame rate, although a lower frame rate can make people sick as well. (I have never gotten sick in VR, so I cannot say if this is the case.)

These days I have a quest3/3080ti, I still use the oculus debug tool but now I turn off adaptive gpu performance scale and disable ASW (Aysncrohouse Spacewarp.) That said, I do occasionally get stuttering.

Obviously the oculus debug tool only works if you are using a quest headset, although if you have a quest 3, that is likely better than the valve index for visuals anyway (higher resolution/better lenses.)

Also, use the "-oculus" sdk with the meta quest 3. (NOT steamvr.)

SOLVED +++++++++++++++++

.
I was always getting stuttering when looking out windows to the side or turning.

Quest 3
Steam Link.

What solved it for me, was even though i was connecting to steam through the head set with steam link... i needed to download the official meta steam link app AS WELL.

Boot Quest 3 up
start up Meta Steam link app on PC
Start Steam VR
Then in the head set link to steam
THEN press start ETs2 in steam..

This doubled my framerate, and zero..ZERO rubber banding or lag and NO stuttering at all.

It would show how many bad out of date mods you are running..

Zero! That's how many I use.
And that is in "zero, I don't use any mods at all"
