Looks like the mission is running. The server is: CombatLogGB. An account on the TAW website is needed to join. There are other requirements as well spelled out in the guide.

I player with the SteamVR resolution settings. It defaulted to 150% resolution. I dropped it to 110% some super sampling still for lense distortion) and that made a huge difference. I was able to maintain mostly 80fps last night on Flyboy's Syria TeamOps practice.

I have used the Valve Index with Steam VR for many years and agree you should be getting better performance.
It just so happens I just picked up the Big Screen Beyond 2 but have not messed with my settings yet so this will get you started. 
First things first, I run the Caucasus map as the base line then test out the new settings on the other maps.  The other maps tend to not run as well as the Caucasus map.
2nd when trouble shooting only mess with one setting at a time.  If you change more than one thing you will be chasing your tail.
Here are my specs
Mother Board is the Asrock B650E Taichi
AMD 9800X3D 8-Core  4.7 GHZ
Nvidia RTX 4090
64 GB RAM DDR5 5600 don't recall the brand or if I did any changes to the timings. If I did it was the mother board utilities.
I did do a small overclock on my CPU off hand I don't know what it is but  its been stable since I got it. You can push that thing with a CPU fan and it does not overheat.
 

 
On a side note for anyone looking at the Big Screen Beyond 2 the 2E does not work with IL2 Great Battles.  According to forums both versions work with DCS.  The 2E is just their eye tracking version.
 

Not really sure, but the 'Home' tab on the TAW link above mentions 'mission 68 of 168'. No mention that I can see re: when mission 68 ends and 69 begins....
I'm looking at how to join. All I can find on the webpage is a 'Login' link in the upper right which allow you to create an account. I opened the account creation page and it allows you to pick a side. I'm assuming this is how you join the campaign. So far it looks like 1 USSR player and 13 Poles. Haven't created an account yet though.

I have been flying the IL-2 Box series and not much else lately. I fire up 1946 once in awhile but none of my squadron mates are interested in it any longer. I used to live in the FMB in 1946 but even that has fallen by the wayside. I tried to find a way to like it but I despise the FMB in the BoX series.

This is looking great so far!

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

Flogger incoming!  The DCS: MiG-27K Flogger-J2, from OctopusG.

They'll be available in... 
So it'll be a while.
 

I should be able to add this to the red inventory for my 1975 YK2 event. 

When I was in the AF I was intercepted by two Floggers North of Norway. Was warned by Scottish Mil and they did a quick overhead pass to check out my WC-135B.

@grok: what year was the MiG-23M Flogger deployed?
1973 (with production starting in 1972).
The MiG-23M (NATO reporting name Flogger-B) was the first major production fighter variant of the MiG-23 series. It first flew in June 1972, with series production running from 1972 to 1978 (roughly 1,300 built).
It began entering service with Soviet units (initially a training/evaluation unit, then frontline Frontal Aviation and some PVO regiments) in 1973. The broader MiG-23 family had an official introduction around 1970 with earlier limited variants like the MiG-23S, but the M was the definitive first-generation version with improved radar (Sapfir-23D), engine, and other systems.

Like Christmas coming early, the MiG-23M Flogger from Ugra Media:

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. 
Level1Techs Forums +1
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. 
YouTube·Level1Linux +2
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. 
Reddit·r/hoggit +2
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. 
YouTube·Reflected Simulations +1
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. 
Reddit·Tuuvas +2
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. 
ED Forums +1
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. 
ED Forums +1
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.
 

Hi all,
 
I got into VR only a few weeks ago.  I've upgraded my GPU to an RX 9070 XT 16GB and then even upgrades the rest of the PC to a Ryzen 9800X3D and 64GB DDR5-6000 (4 DIMMs downclocked to 5600MT/sec).
 
I still am having issues with frame timing with anything more than a small single player mission.  On Flyboy's training or Syria servers, I average 20FPS in VR and I have everything pretty much set to low.
 
Can we compare eachother's performance by specifying what hardware and settings we're using?
 
FWIW, I get pretty good framerates on a 1440p monitor and high settings. 
 
CPU: 9800X3D
RAM: 64GB DDR5-5600
GPU: Radeon RX 9070 XT
VR/Screen: Valve Index
Launcher: Steam/SteamVR
OS: Void Linux 7.2.10
Average VR FPS on Flyboy training server: 20

I have seen the first couple of seasons of the Reacher series on Amazon Prime starring Alan Ritchson so now I am going to start giving the books a read. It's likely not in order of publish date but a friend loaned it to me so I started with In Too Deep.

I watched all 4 episodes of the 4 part docuseries Tyson (IMDb link) on Netflix a couple of days ago. If you have followed Mike's career over the years this documentary series doesn't really cover much new ground. I personally enjoyed watching the series just to see Mike but don't expect any hidden or up until now unknown revelations about his life or career.
One final note, Love him or hate Mike after he went professional and ended up retiring boxing has never been as exciting as it was during his ascension to the title in his early career. He definitely did seem invincible during that rise. Imo, you had to witness his career as it happened because archival film and interviews just does not do the buzz a fight of his generated during that era justice.
