Quest 3 - Shaky/Vibration

[Paul6JAFO]

Hey all, I just started playing DCS a week ago on my new rig. GeForce 4090, AMD Ryzen 7 7800X3D, 64 GB RAM DDR5 6600, 4 TB SSD, 1000 W power. I have a Quest 3 VR headset that started out great. DId some tweaking based on reading threads here, Reddit, and YouTube, and something started causing my headset to "shake" when I'm playing. It's almost like the headset is loose and vibrating with any head movement. It is very disorienting. Using the DCS MT version with OpenXR Toolkit turbo mode, Quest Link, resolution set to the highest setting with 72Hz. Also using the Oculus Tray Tool.

I can't post a screenshot of my in-game settings at the moment, but here are the basics:

Res 1920 x 1080, res of cockpit displays 1024, MSAA, 4x, upscaling off, sharpening .80, textures medium, terrain textures high, shadows low, clutter/grass 400, forest 70%, details .65/.65, gamma 2.0, lod switch 1.5, VR PD is 1.2. The visuals are great, and I'm getting the same stutter at a PD of 1.2 or 1.8. I also reduced a lot of settings and still am getting the stutter with much lower resolution. So I either have the game looking incredibly detailed with stutter or looking blurry with stutter.

In game frame rates are a solid 72 fps across the board with very little bumps in the line. 

Using a hard-wire to the PC with the Q3 using a link cable USB-C.

Any thoughts here?

So, ditch the accessory items like OXRTK turbo and OTT. Set the in game PD to 1.0 and Meta software to 1.3 at 72HZ which is then max resolution with the slider all the way to the right. Set the DCS preset of VR and test. These are kind of the minimum settings and then work your way up from there. Trying first with settings in game and not OTT or OXRTK as many have issues with Turbo Mode and OTT PD settings, some its fine and everyone's PC and tolerances for VR are different. Next if that works start with 2x MSAA and adding more details like cockpit res.

Once you get the basics going and not stuttering, then QuadViews with your CPU should help. Even though the Q3 doesn't have tracking, it will still work in fixed foliated. For me I could not get it to work well but my CPU is older gen. You may not need this at all with a 4090, but if you want to run MSAA 4x and higher graphic settings like clutter/grass, forest and LOD, you may need it.

The Res of 1920x1080 is the mirror image on your PC while in VR, so change that to the minimum.

What does your cable test at in the Meta software? It should be about 1.4Gbs.

I ditched Meta for similar issues and use VD, but that does also require a solid WiFi connection. Mine is a dedicated WiFi 6e and VD works much better for me.
