There's a fix for the AMD BIOS since AGESA 1.2.0.2

Multiple things can cause this on the G2: - Firmware. There was a firmware bug that caused the screens to blank when the audio level was high. Fixed with newer firmware - Low frame rates. If your machine can't sustain high frame rates, the G2 might go dark for a few seconds. Reducing refreshrate to 60Hz helps. - Bad cable. One of the things that are known to break on the G2 are the cables. - Overheating. The G2 get's pretty warm. Sometimes too warm. Don't invest in the G2. It's dead Jim. Better go for a Quest3 or a Pimax.

This loadout will block the gun, Sidewinders and Sparrows. (See included miz file BLUE-DODGE-4-1 to demostrate the bug. For reference a simpler loadout on BLUE-DODGE-4-2 works fine) Haven't yet tried to fire the Shrike, Maverick or FFARs. I'm not sure if it's a weapon systems bug, or just a bug in the mission editor allowing a invalid loadout. F-4E-WeaponsBug.miz

That's one of the 28 bunkers on a former Pershing Ia QRA site near Schwäbisch Gmünd where the 56th FA-COM HQ was located. Also nearby is the former Mutlangen Pershing II MSA.

Only if you're short on RAM, cores and memory bandwith. Otherwise the physical network will cause higher latency then running the server via loopback 127.0.0.1. I've added my heavy load scenario mission if you want to give it a try to compare single player VS dedicated server. My 2 reference aircraft are F-4E BLUE-PONTIAC-1 to fly in close formation with 4 QF-4 drones to shoot down and F-16 BLUE-JEDI-1 over Berlin. In Multiplayer VR i get solid ~70 FPS with some exceptions over Berlin when it sometimes drops to ~60. In single player i only get ~30 on BLUE-PONTIAC-1 over the sea and i won't talk about the FPS over Berlin in this heavy load scenario You'll have to experience/suffer from it on your own. Singleplayer 30 FPS ... Multiplayer 70 FPS ... DePerformanceKiller-I.miz

Heavy load scenario DCS standard alone Only two DCS threads + OS are used. (~20% usage of 16 cores ~ 3 cores) - render thread - main thread - OS Memory usage 59GB, FPS dump into the 30s., Graphics card can't get enough data from the CPU. Same Heavy load scenario DCS multiplayer server + DCS client. Multiple threads are used (~30% usage of 16 cores ~ 5 cores). Memory usage 81GB, FPS stable around 72 FPS. Graphics card get's feed enough data from the CPU. null Btw. you can see the almost twice higher frame rate to the Quest3 on the ethernet "SEND" graph as well. ~70 vs ~30

You could offload computations to more threads on other cores using a DCS multiplayer server on your local machine and to limit max FPS slightly above the physical frame rate of your googles, so the DCS client has more time in main thread. This usually gives a high performance boost. It also helps in VR with NV GPUs to massively reduce resolution and use DLSS to scale up.

My 2cents on VR performance i've recently discovered: For Quest3 with AMD GPUs currently the best OpenXR runtime is VirtualDesktops VDXR. It provides the option to use a codec that will give you excellent image quality on AMD GPUs and performs notably better then SteamVR and Meta-/QuestLink. Meta-/QuestLink is pretty much unusable with DCS on AMD by image quality from the lousy codec and the desasterous performance on AMD. The current AMD drivers are also very CPU sensitive, much more then NVidias drivers. If you're CPU is under load your frame rates will not only plummet, they're in a free fall on a AMD GPU. And always use the latest driver. Differences can be enormous. Adrenalin 25.3.2 -> 25.4.1 was giant leap in VR performance. For Quest3 with NVidia GPUs currently the best OpenXR runtime is SteamVR. It performs notably better then Meta-/QuestLink or VirtualDesktop VDXR. On NVidia the worst runtime is also Meta-/QuestLink, but on NVidia it provides still acceptable performance. On NVidia VDXR doesn't perform as well also. It seems like VDXR is optimized to fill the gap for a usable AMD OpenXR runtime at the cost of performing on NVidia. A recent RX9070xt with all the tweaks (encoder, VDXR, FSR upscaling...) still lacks way behind a 5 year old RTX3090 in performance even in scenarios where VRAM isn't a issue.

I'm currently trying to get more performance out of my sons rig with a 9070xt. Biggest improvements yet: Adrenalin 25.4.1 which was released yesterday. This boosted performance quite a lot Using VirtualDesktop instead of MetaLink and SteamLink. This not only boosted performance, but also image quality due to the better codec. Other findings: The AMD drivers on the RX9070xt are heavily relying on the CPU in VR compared to a NVidia RTX3090. The 9070xt it self doesn't seem to be the bottleneck, but the way how the driver works.

Yes. Especially the visual quality from the codec improved so i now can read the gauges again. But performance is still nowhere close to the 5 years old NVidia 3090 ... I've tested 2 scenarios flying in close formation to see how much the driver wastes GPU time over CPU time. A light load scenario flying along some tankers with some escort birds (2 x F-15C, 2xF-16CM) Not much CPU load, but more graphics And a heavy load scenario flying behind only 4 F-4Es, but a lot of other stuff going on on the map making the CPUs life hell to see how much this influences the driver. This was also the scenario with the most spread over the configurations. Going down to a bizarre 3 FPS with MetaLink and Adrenalin 25.3.2 up to 40 FPS with VirtualDesktop and Adrenalin 25.4.1 The biggest performance improvement was yesterdays Adrenalin 25.4.1 release. BUT it's extremely CPU sensitive. It seems the AMD drivers rely much more on CPU performance in VR. The GPU it self was never the limiting factor on the RX9070xt system in VR. I'm going to buy VirtualDesktop for my googles too and do some more 1:1 statistics RX9070xt vs RTX3090 and MetaLink vs SteamLink vs VirtualDesktop. But this has to wait until next week, because my son took his rig to some friends house. They're spending time from thursday to sunday on pizza, coke and gaming in the basement ...

The SI-standard unit for radio bandwidth is Herz not bits per second. https://x.com/i/grok/share/9OKZR7ERUrsYLpTvpIBUXyshU

Alright then Sailor, as long as you don't show up with at least a HAM radio license certificate i don't believe you anything.

Dude, you lack basic radio knowledge. Perhaps it would be a good idea to look up how radio transmission actually works.

Dude, channel width is literally the bandwidth of the channel. https://en.wikipedia.org/wiki/Bandwidth_(signal_processing)

I already have a dedicated 5 GHz 80Mhz bandwidth WLAN AP directly connected to the PC.

Just invested the 30 bucks in VirtualDesktop ... Let's see tomorrow how it'll perform ...

Issue solved with the new Adrenalin 25.4.1 drivers that got released today.

They're using VirtualDesktop and not the usual out of the box VR link systems like QuestLink or SteamLink. With todays new Adrenalin 24.4.1 drivers things got way better, but the RX9070xt is still miles away from my half decade old RTX3090. What's most surprising is that QuestLink really sucks in performance and picture quality of the codec compared to SteamLink. Maybe i should invest 30 bucks for VirtualDeskop ...

It was a sobering experience. 2D Performance is great, but it sucks in VR. Already opened a support ticket with AMD over the devastating performance, the horrible quality of the codec and opened a ticket with ED over graphics failures in VR with the AMD card.

Part of the Jester menu is cut off in VR on a RX9070XT. The Jester menu in the F-14 is not affected, and the F-4E Jester menu works in VR with a NVidia graphics card. Overall performance on the RX9070XT in VR is pretty bad. Therefore it seems more like a AMD issue, then a F-4E issue. Both rigs use a Quest 3 via SteamLink/SteamVR on a dedicated 5 GHz WLAN. AMD rig: RX9070XT, Adrenalin 25.3.2, Ryzen 7 5800x3d, 128 GB RAM, BAR enabled, latest BIOS AGESA ComboAm4v2PI 1.2.0.E Nvidia reference rig(not affected) RTX3090, Nvidia 572.83, Ryzen 9 5950x, 128 GB RAM, BAR enabled, latest BIOS AGESA ComboAm4v2PI 1.2.0.E

No issues here. But i'm offloading CPU load to the dedicated server to make more use of all cores and i'm massively using the BAR feature to push textures into system RAM. This comes at the cost of a lot of RAM. I'm currently using about 90GB of the 128GB in the system.

You can make good usage of the 9950x3d when you run the DCS server on the non-cached cores, while running the DCS client on the cached ones.

ALEA IACTA EST Just ordered a RX9070XT OC https://www.xfxforce.com/shop/xfx-mercury-amd-radeon-rx-9070xt-oc-gaming-edition-with-rgb

I got the odd Steam state fixed by installing the latest update for the standalone DCS server. Steam then did a successfull rerun of the update for the steam client version and verify in steam succeeded.

Already did this. DCS is in my Defender exclude list since the F-14 and F-4 issues a while back, the disc i've installed DCS has 1.9 TB free space and verify in steam doesn't really do anything besides tell me that "All 0 files successfully validated". Retry of DCS update gives either a "MISSING DOWNLOADED FILES" or "DISK READ ERROR". Ticket is open #183972.
