Finally installed my 5800X3D paired with a 3070ti and it seems to be bit better than my old 3700X but is not stable.
If sit at the gate in a payware airport, I get 45-50fps outside view, as soon as I pan around the FPS drops to 20-30 fps for a good while until I stop which it will then go back to 45-50fps after few minutes until I move around again which tanks the fps.
My TLOD is set at 200 and I’m using TAA, DX11 and 1440p resolution.
The temp was really high, 70ish with up max recorded 88c. I did the PBO undervolt -20 and now sits 50c-60c with highest peak recorded of 70c, but not difference in performance.
The in game FPS counter is continuously flipping between limited by GPU and limited by MainThread simultaneously.
I had the 6900xt in the past paired with a 5900x and was getting around 43-52fps from ground to cruise altitude (CRZ over 60fps). And no way I could get that with everything set to ULTRA.
The 5800X3D is way better than the 5900x I had so he could get a little performance uplift. Also over Dx12 the CPU was botlenecking too much on that CPU, I don’t know how much of a difference it could be over the 5800x3D tho. But at that time with that GPU/CPU combo had more loading yellow lines in the cpu graph (which was mainly green) over Dx12 than over Dx11.
No chance in ultra to get over 60fps on the ground.
Also is not standard 1440p (2560x1440) but widescreen ratio 1440p (3440x1440), so more demanding.
You have to tweak here and there:
-Lower shadow setting for all
-TLOD “is fine”
-Texture Synthesis can be set to Ultra
-Buildings, Trees, Grass and Bushes go to High or Medium for the latter and Trees
-Raymarched reflections to high
-Terrain vector data is fine at ultra, but can be set to high.
-Ambient Occlusion go to High or Medium
-Off Screen Terrain Pre-Caching… it has its caveat. The higher the setting the less fps you will have, but the smoother the panning will be. I had it set to Medium or High. You can lose a lot moving it from Medium to Ultra.
-The rest of them seems fine, although I had all set to 25 in the Traffic section, except aircraft density that was ofc set to 0.
But first try over Dx11 instead of Dx12, and check the differences.
My 10700k had more consistent frames even with Fenix. I just do not understand why the fps is fluctuating constantly with the 5800x3d when moving the camera around especially with Fenix!
I notice the clockspeed on the 5800x3d is constantly fluctuating causing fps drops.
yep, if everything is the same, something is not working as indented. Check all drives, gpu included.
Also enable PBO if possible. If you don’t wont to mess with the curves, go for the auto atm.
Have you set the TLOD to 100 and seen the same drop when panning around the payware airport? From 10-to-100, increasing TLOD adds more detail to nearby objects. From 100 to 400, about all it does is to gradually increase the distance from the eye at which it adds in rendered detail. I don’t think that the 200 setting is getting you much extra detail over a setting of 100 when looking around an airport, so I’d expect that reducing that setting would help the FPS drop you experience in that specific scenario.
I have a 5900x with a RX 6800 (non-xt) which is close to your set up and it runs butter smooth. I have a little more cpu, you have more L3 cache however you should win out with better fluidity. Below are my settings which may or may not help.
Turn off all options in the Adrenalin driver (set to defaults)
Display mode = Full Screen
Full screen resolution = native resolution of your monitor
Turn on vsync in the sim. Set the frame rate limit % to target 40-60fps based upon your monitors refresh rate. So if monitor is 120Hz refresh set % to 33% or 50% (I have mine set to 33% = 40fps locked)
Turn on FSR2 with quality (or balanced) settings
Use DX12 as AMD GPU’s run better with it especially w/16gig Vram
Set Global rendering quality to ULTRA (let TLod and OLod default also)
In the Data section, turn of rolling cache
Using the Adrenalin driver, clear shader cache
Turn off FSLTL and other add-ons temporarily until you get your performance sorted out. They are only complicating things for you at this point.
For me, the sim runs butter smooth with the the RX 6800 between 60-99% utilized. My CPU runs 10-35% utilized (using Win 11 taskmgr to measure both). I’m typically GPU bound at 4k resolution with HDR10 turn on except when I’m close to the ground in dense airports and other complex areas.
This is the cause of the performance issues. Can also affect CPU. Two solutions, new GPU with more VRAM, lower settings to lower VRAM. Nothing that the CPU can do here sadly.
Yep, I have 5800x3d and 3070 also, its fine for GA, in the countryside, but if you want to fly the Fenix into new 3rd party big international airports, I’m afraid it is just not enough VRAM anymore.
I am waiting for my 4090 to arrive, but also need a new case and PSU, so gonna be a faff!
Don’t forget AMD processor drivers are a separate download.
A word of warning to MSI mobo owners re downloading MSI centre. It’s been known to sometimes cause a non booting situation so make sure you know how to enter safe mode in case you need to uninstall it.
Oh my gosh I feel so dumb!!! Problem is solved. Culprit was outdated chipset from 2015. I am now on the latest version from 2022. Its run much more fluid than my 10700k did! I know with Intel the chipset drivers are done through windows. I had no idea with AMD it has be downloaded from their site. This is my first AMD cpu btw.
Mark this travelers. And try to do this whenever you need to update drivers.
Keep Windows without internet connection.
You can avoid this by enabling in Windows Local Policy Editor: Do not update drivers via Windows Update
Even with that I always keep the ethernet cable unplugged when updating drivers. For example updating gpu drivers after DDU.
A good practice is to download first all the drivers you will need and keep them in folder or pendrive prior update. In case of fresh install do not let Windows connect to internet (you can skip the internet setup on Windows 11 install via CMD).
Also, do a fresh Windows install when changing motherboards
