Rift-S stutter

[underscore]

Hi all

 

my last hope before I have to put this game to sleep

 

any fixes for a stutter when running on Rift-S

 

no stutter in any other VR games incl DCS

graphics settings do not seem to impact

forcing ASW on or off or auto makes no odds

 

 

any thoughts appreciated else i’ll have to check-out of IL2

Make sure in graphics setting neither vsync nor fps target is set.

Did it run well at any time?

Tried a clean reinstall?

Do you run MSI Afterburner or something similar?

 

I only have Rift CV1, since it has different tracking method i don't know if it is the same issue.

Most of the time when i have stutter problems was, when station calibration was somehow off.

After resetting VR, stutter was mostly gone. 

Maybe the issue isn't apparent with other VR titles, because error correction can compensate it. But since il2 is more demanding, the issue becomes apparent?

could be worth a try, try different USB3.0 port

It may be circumstantial, but I was getting constant stutter in my rift s. Even if frames were good. I unchecked 4k textures and haven't had any stutter since.

Hi All

 

Thanks for the feedback

Tried a different USB 3 port 

Tried re installation even to a different SSD drive

Tied various graphics settings

 

 

it did run smoothly some time back

 

 

interesting I can see non of my CPU's are at 100% and the GPU s only at about 50%  so something must be a bottle neck - I'm guessing steam VR??

 

any way - I'll check back to see if any other solutions come up - until then no more purchases of content from me and the game will go to sleep :(

Consider giving Open Composite a try.

A program that allows one with a Rift device to run through it rather than Steam VR.

I use it and get better performance in IL-2 with it.

Same issue with open VR

 

not sure why CPU and GPU usage would run low??

Hard to say what exactly it might be, however it is odd you would be smooth in DCS and stuttering in IL-2. And really odd you did not

see an improvement with Open Composite with IL-2.

Typically DCS is more demanding on VR than IL-2 is. At least I find it is. I am smooth in both however with my Rift S, but I do also have a pretty beefy rig.

What are your system specs?

How do you have your in game graphics settings set?

If running an Nvidia card, do you have IL-2.exe set in Nvidia Control Panel to " Prefer Maximum Performance" in power management? I leave all the other settings at their default of "application controlled".

In game settings all around medium but even on low or high I get the same thing

 

Nvidia set to prefer max performance 

 

must be something interfering with the thread in IL2...... will try something like ‘win10 game mode’ to see if that helps
 

my sys specs 

---------
System: i7-8700k @ 3.7 to 4.7GHz; Nvidia GTX 1080ti; 16GB DDR4 2666Mz Ram; ASUS ROG Strix z370-E; SSD Drive; Oculus Rift S; Thrustmaster HOTAS Warthog

Valve Index here. And still stuttering even on berloga.
However i didnt doublecheck if FPS target or VSYNC are off. Will do that in the evening.

Check all your running programs in task manager and see if you have something eating up some of your cpu resources.

Hey Winger,

Fellow Index owner here... did you managed to get rid of your stuttering?

Nope, but i have to admit i dint try much.  Dont get to play too much and if i get time i rather play something in VR that deoesnt stutter.
EDIT: I am sure they will fix it soon. They always eliminate bugs like that sooner or later.
