Problem in VR (oculus)

[vince007]

Dear Lockheed team,
I've installed the 4.2 version (updated my 4.xx), but now, i have found some problem in VR.
1) It crash sometimes when i swith to VR.
2) When i look on my right (or my left), that's ok, same things for the up and the down, but when I lean my head towards my shoulders, the movement is not synchronised...its amplified... ( and i feel like throwing up.:-) )

System: W10 pro 64. 64 Go, Sli of GTX 1080 ti, I76950X

Which version of the Oculus driver/runtime?
Which graphics driver?

I recall getting a report about bank being incorrect on Oculus but it was related to the a GPU or Oculus driver and resolved itself after updates. There are some known driver versions and oculus home versions that don't work together.

Hi Beau,
the firmware is of the headset : 708/34a904e8da
App oculus 1.24.0545657 (1.24.0547103).
Oculus driver 1.18.0.426075

Everything is on automatic update.

Hi Beau, I've updated the nvidia driver (397.31) and the problem is here, again.
Done a clean install of the driver.
Have you any suggestion? The game is unplayable in VR.

Hello,

Do you have SteamVR installed as well?

Have you tried deleting your generated files?

Hello,
Yes, i've steam VR installed as well, but it's not lauching at the same time.
All the other game in VR, in steam, or oculus haven't got this positional problem.
No, i haven't tried to delete generated files. What is the procedure?

Hello,

We have seen occasional issues with both Oculus runtime and SteamVR installed. It'd be great if you could test this after uninstalling SteamVR.

Deleting the generated files involves just deleting the following folders:

%PROGRAMDATA%\Lockheed Martin\Prepar3D v4
%LOCALAPPDATA%\Lockheed Martin\Prepar3D v4
%APPDATA%\Lockheed Martin\Prepar3D v4

Hello,
I've done the thing you tell me.
Result = the same.
I going to try to disable my sli.
Any other suggestion?
Vincent

Edit: Disable the sli, nothing change.

The problem, only appear when i lean my head, 15° in real, turns into 45 in VR.
No problem in any kind of game (Xplane, DCS for example).
