VR - Heavy shimmering in Mirage F1 cockpit only

[CPS_Bomber]

Hi all

Anyone here flying the Mirage F1 using Quest 2?

It's most likely a setting or settings I need to tweak on my system, but the cockpit overall and instruments are generally very shimmery/sparkly, in particular the ADI (artificial horizon) and the covering for the control panel (especially on the upper left) look almost like glitterballs. Not only does it make many of the instruments and dials difficult to read, it's very uncomfortable for the eyes.

I have all the flyable modules in my collection, and this is the only aircraft I'm seeing this really exaggerated effect in, and it's present in the F1CE, EE and BE.
External views are perfect.

It's all fine in 2d using TrackIR.

I have access to both standalone Beta and Stable with normal or MT versions (so no DCS Steam install).
I'm currently using standalone Open Beta MT with 2.9 update.

FXO and Metashaders2 folders emptied after update + last hotfix installed.

I also use Viacom Pro/VoiceAttack (not that that should make a difference?)

I'm using Quest 2 with cable via USB3 hub (all updates installed). It's set to 72hz with default 1.0x 4128x2096 resolution setting.

I also have Oculus Tool Tray installed and OpenXR tool kit.

I've got 32gb RAM, Nvidia 3090ti (latest drivers), 1000w PSU with Win10 home premium fully updated with DCS on an SSD and windows on an NVME.
On 2D with TrackIR I can run maxed out on all maps (except for Sinai and Syria when things get very busy I notice a drop in performance).

In-game settings for a balanced smooth and clear performance in VR are:

SYSTEM
Res 1920x1080 (desktop Res is 3440x1440)
1 screen
1024 every frame
MSAA
4x

Terrain object shadow off
Cockpit global illumination off
Font scale 1
Scale GUI 1
Rain droplets on
VSync off
Full screen off
Cursor to game window on

VR
Pixel density 1.2
Force IPD unchecked (value in box states 63.5)
Bloom effect off
MSAA mask 0.42
HMD mask off
VR mirror Use DCS resolution on
Eye source right eye.

My Nvidia control panel has a profile for DCS, but everything is set to default/global setting except:
Power management mode - pref max performance
VR pre rendered frames - 1

The basic setup was done using the latest tutorial by Laubox as it covered both 2.9 and Quest 2, and all in all this is the clearest and smoothest I've had it all running:

Any suggestions as to where to look at settings to tweak?

Thanks in advance for any suggestions and advice!

Cheers

Hey, I had the same problem and I tried to increase the resolution to around 6-7. This decreased the "sparkling" quite a bit without affecting the FPS too much. If you have found another way to make it go away please let me know!

I am no expert, but I hope this helps
