Looks pretty good so far. I wonder if it's better or worse without Jason. Seems like it was his initiative to get this started but he can be... 

If you travel at near light speed it might actually seem to be available in Two Weeks "relative" time. 🤨

With your hardware you should be getting MUCH better performance.
Here's what Google AI says (maybe ask other AI as well:
AI Overview
Low performance in DCS World multiplayer via VR on Linux is typically driven by a combination of Proton/OpenXR runtime overhead, SteamVR limitations under Linux, and missing environment overrides. Your top-tier hardware (
AMD Ryzen 7 9800X3D
and
Radeon RX 9070 XT
) is more than capable, meaning your bottleneck is strictly software configuration.
Apply the following targeted optimizations to stabilize and boost your multiplayer framerates.
1. Fix the Linux OpenXR / VR Environment Call
DCS heavily favors OpenXR. Running it via standard SteamVR paths on Linux without passing explicit environment flags forces suboptimal Translation Layers.
Open Steam, right-click DCS World, and go to Properties.
Paste the following into the Launch Options to force proper OpenXR device initialization and bypass the heavy SteamVR launcher wrapper: 
ProtonDB
bash
PRESSURE_VESSEL_IMPORT_OPENXR_1_RUNTIMES=1 OXR_RECENTER_STAGE=1 WINEDLLOVERRIDES='wbemprox=n' %command% --no-launcher --force_enable_VR --force_OpenXR
Use code with caution.
2. Verify Your Mesa & Kernel Compatibility
The
Radeon RX 9070 XT
runs on AMD's newer RDNA 4 architecture. On a rolling release like Void Linux, a mismatch in recent drivers can cause severe performance regression or failing pipeline optimizations.

Ensure your system is updated and verify you are running at least Kernel 6.13.5+ and Mesa 25.0+.
Ensure your linux-firmware package is fully updated to ensure the firmware binaries for the
9070 XT
are correctly mapped.

3. Lower CPU-Bound In-Game Settings (Multiplayer-Specific)
Multiplayer environments stress your
9800X3D
's tracking capabilities due to high unit counts and network parsing. High graphics settings in VR will induce severe 1% frame drops.

LOD Switch Factor: Drop this to 0.4 or 0.5 in the graphics settings. In VR, the slight reduction in distant object models is barely noticeable but saves massive amounts of draw calls in busy multiplayer servers.

Preload Radius: Set this roughly between 60,000 and 100,000. Your 64GB of RAM can handle it, but setting it too high forces unnecessary caching over network states.

Shadows & Civ Traffic: Set Shadows to Medium or Flat. Turn Civilian Traffic completely OFF. 
YouTube·Yorick! +3
Upscaling: Since you are on AMD, enable FSR (FidelityFX Super Resolution) or native DLAA (if utilizing Proton's DLSS-to-FSR wrapper translation) rather than running at an un-upscaled 100% resolution scaling.

4. Clear Your Shaders
Corrupted or outdated shaders compiled under older Wine/Proton prefixes often cause heavy micro-stutters and frame drops.
Navigate to your DCS installation directory or your local WINE prefix path (typically under ~/.steam/steam/steamapps/compatdata/223750/pfx/drive_c/users/steamuser/Saved Games/DCS/).
Completely delete the contents of the fxo and metashaders2 folders. They will safely rebuild cleanly on your next startup. 
5. Check System Monado Alternative
SteamVR's native Linux implementation is notoriously unoptimized for complex VR loops compared to its Windows counterpart. If you continue to see poor hardware utilization despite the tweaks above, community consensus for high-end Linux VR points toward running Monado paired with Envision or WiVRn to completely bypass SteamVR’s compositor overhead.

What Proton version are you currently using to force the game (e.g., Proton Experimental, GE-Proton)? If you pull up a frame-time graph, let me know if your stutters point to a CPU frame-time spike or a GPU bottleneck.

Two Weeks™

Nonsense! 

I'm pretty sure she was universally respected, liked and even loved. A real class act even though she said "It takes a lot of money to look this trashy". We lost a special one. This brings tears to my eyes:

Well I didn't expect this to be my first video on my Flyboy Ops YouTube channel, but was told by flight control they caught my landing into Miami today so I found it, clipped it, and put it as the first video on my new channel.

I just got the Pimax Dream Air SE. The visual clarity is AMAZING! Close to real vision. The FOV is narrower than Pimax Crystal and I assume the Crystal Light but I'm willing to trade that for the resolution. It came with the old style facial interface but they are sending a revised interface which moves eyes closer to the lenses which increases FOV. There is also new software and drivers which I have yet to try.
