Mine is 4K on 1 monitor. MSFS and Win 10 installed on a M.2 PCIe 4.0 card, 32GB DDR4 Memory, i5 11400k , 10GB RTX3080, Render at 100%. Terrain resolution 150 and mostly Ultra settings.
Hm so it might be AMD related after all.
DX11 or DX12? I use DX12 on Win11 due to generally better performance in my case
I use DX11… DX12 does some strange things. Also I definitely don’t use the Nvidia “Auto Optimise” function which suggests / uses DX12 for my system.
Thanks for the info. I just compared DX11 vs DX12 on my PC to see if something has changed or if it improves the F111 performance: DX12 still runs better for me (no matter what plane).
Additionally, I now used the FS2020 FPS analysis DevMode to check the F111 and that confirmed my theory about the CPU overload: it constantly shows “limited by main thread”, meaning the CPU can’t feed the GPU fast enough, therefore low GPU load.
On other planes it’s “limited by GPU” for me, resulting in correct high GPU load.
So in short: F111 doesn’t like 5800X3D 
I have a 2080 and have decreased performance too, though mine seems to be related to having weapons loaded.
I am using DX 12. I12700K with F-111 CPU between 65 - 73%, GPU 100%. I have made the following changes in the nvidia panel:
Anisotrope 16x, Latenz Ultra, Textur anisotrope off, negative LOD Clamp, Threaded opt. on. No problems with DX12. FPS also depend more on the weather conditions. Sometimes other big planes need more CPU power.

Does anyone else have the vapour trails from the wing tips being out of sync?
All due respect, there are several planes in this sim that have moving map gauges and simulated radars without any noticeable performance penalty. The F-22 and F-35 off the top of my head for example.

Having to bind some peripherals, I went to the -model- folder to look for the xml file to copy the LVAR vars. But I can’t find the file in question. Can you tell me where it is? I already looked in the main folder. Thanks in advance
Want to purchase but need to know what the system requirements are before I do. Can someone post CPU, RAM and GPU specs? Thx
any suggestions?
You can see some spec examples above in the discussion about performance, including mine.
I am currently having FPS issue with the plane due to CPU overload, so that my GPU cannot run at appropiate speed.
5800X3D, 7900XTX, 32GB DDR4 3200Mhz
Are you guys still working on a Orbx release?
I’m installing this now - the F111 is a long time favourite of mine, my country was the last in the world to fly it. I was fortunate to see it in action many times. It’s a beautiful machine.
Yours looks stunning. Happy to see the ARDU scheme.
Will run it with a Radeon W6800X 32GB card and W3275M Xeon 28 2.5ghz. It’s my work computer but it has Windows and Flight Sim on another SSD. 
Edit: Oh man - this is awesome! 
In VR it is beautiful.

My first experience with it:
Just beautiful. 8)
I flew from Richmond (YSRI) to Sydney with VR. It’s very engaging. I had smooth FPS and no stuttering the whole time even with the horrible weather (heavy cloud and rain).
My machine is very different to a lot of others here:
Intel Xeon W 3275M 28 cores / Radeon Pro W6800X 32GB MPX / 48GB 2933mhz ECC RAM.
I have the book from Mark Lax and first thing was to jump to the ARDU colour scheme. All it is missing are the test markings on the side.

i love flying this thing! God Bless up!

Pretty good airplane, but as noted above needs work. Nice flight dynamics and handling especially down low. My recommendations for improvement in the near term: 1) Fuel flow is about 1/2 of what it should be… e.g down low should be burning 12,000 to 18,000 lbs/hr. depending on the specific conditions. 2) When in autopilot HDG Mode , navigation info should be visible on the HSI so you can use the HDG Mode. 3) Needs GPS/INS. 4) CFG files in Community would be fantastic.

Have you reported these observations to GKS? They don’t always check the forums here.

Do you by any chance have the best way to contact GKS ?
