CptBayer - the thing I run is called “HiWinFO64” my pc builder suggested it. It provides stats on every possible sensor point, I just worry about the temps. I do not think I have hit 60C yet. Going to test tonight with another 747 flight to see if I can get it down.
What’s the best program to keep track of temps?
16g is okay but 24g is even better. The card wll use what you have so the more you got the better performance. Im not a guru on anything but these are my observations. Josh

24gb is seriously not needed for 2D lower resolution where most simmers are at. I rarely go over 12gb on my card and that’s 3440x1440 with payware airports and airliners on mostly ultra settings so no “the card will not use what you have” Unless of course 
For the privilege few that have a 4090 4k screen, high res VR headset.
Your own screenshots show the render thread in the green and you’re getting 90 fps (with frame doubling DLSS 3). Doesn’t seem so bad to me. 
right now I have a 3090,also 24 Gig. I am running on 4k and I reached at special sceneries round abozt 18 gig´s … When I lower the resolution round about 6 gig´s less … So for me I think a 4090 is the safe side … isn´t it ?
Just installed my new RTX 4080 and was getting poor frame rates like you , tried different settings no joy , then I installed GeForce experience and optimised settings , now I’m getting 80FPS in a high detailed airport with fsltl
I’m at 140 fps in air and over 100 in cockpit with a PMDG
So my solution was to install ge force and let it optimise settings
Temps are really cool on a slightly overclocked 12600k
Hope that helps

Hi Guys,
Am I expecting too much?
Here are my specs:
RTX 4070
Ryzen 7 5800X3D
16GB 3200MHZ Ram (will replace to 3600MHZ 16CL soon)
1Tb SSD
There is no way for me to gain stability when flying a 3rd party aircraft at a 3rd party airport with no traffic.
For instance, LOD at 150 will give me 40-50 fps when standing still in the cockpit but looking left or right will give me 10-15fps or all the way down to single digits. This is obviously unplayable and the only solution is to limit LOD at 100 or lower which my 3070ti 12700k laptop was able to handle just fine as well. I bought a rig just to play flight sim and I can’t even enjoy the sim. What happens when I start using traffic or fly at VATSIM, do I need to lower LOD to 50 just to enjoy the game? Even low LOD does not make looking around the cockpit any smoother. Looking up and down causes huge stutters. I have disabled hardware acceleration in the BIOS, I have set the cache in the NVIDIA Control Panel to Unlimited (and cleared it) and I have enabled game mode etc, all the little tricks.
I simply want 30 fps at Full HD with very good visuals that would make use of my system to the full of its capabilities. I am mostly limited by MainThread but looking around makes it flicker between GPU and Mainthread. All my other settings are at ultra but lowering them doesn’t really make a difference. Anti-analysing is TAA as DLSS makes frame drops worse.
DX11 is generally more stable but the fps hovers around 20.
Any tips? Settings to turn down? System changes?
I have optimised the GeForce settings , so try that
I think 32gb ram might help also
Also you need to enable HAGS in graphic settings on windows 11 to enable frame generation
Also try an external fps counter like riva tuner

At full HD (1920x1080) that’s the performance I’m getting with a Ryzen 3700X, Radeon 6800XT, 32GB RAM, scaled at 135 (so near 1440p rendering resolution). I’m a little lower on the highs but the lows are similar so you’re probably hitting an edge on the optimization of FS.
Unfortunately there’s no linear progression between hardware and performance. Sometimes people with similar specs get better performance, sometimes worse performance, and sometimes upgrades do not have the (reasonably) expected impact.
As an example I went from a 2060 12GB to the 6800XT. Per the specs and tests comparisons between GPUs I was hoping a real jump in performance. Nevertheless, the stutters were still there, the fps drops were still there, the hiccups were still there.
After spending a lot of time tweaking I decided to just fly and take 15fps landings as a Microsoft Landing Challenge, Spotlight Event 
Edit: seriously speaking, things like AI traffic, add-ons like FSLTL and particularly some custom airports (cough, inibuilds klax, cough) and some custom aircraft are frame eaters. Also consider that several users, I included, have noted a significant performance drop after AAU2
They are frame eaters because they use CPU. The more CPU they use they take from the CPU needed to make frames to send to the GPU. If the GPU doesn’t receive frames fast enough, it has to wait.

Ye but he has a 5800X3D, highly doubt that CPU is bottlenecking a 4070.
Yeah, I guess until we have a better optimisation (which is probably never coming) I will have to rock lower LOD. I have never seen a game like this before. Previously, on my laptop, 4k was giving me better fps than FHD and I anticipate the reason was the CPU bottleneck.
The fact that the game is CPU limited, yet the CPU runs at like 40% tops and 60 degrees to me has no excuse. I bought a CPU specifically recommended for MFS yet, I still get stutters and gitters. Yes, overall better performance than what I was getting from my laptop, but less consistent which is simply annoying. I reckon my slow RAM is not helping and I will make the switch, but I do not anticipate a major gain of stability at this point, just because of the number of disappointments I have had with the simulator.
I truly think about switching to X-Plane at this point because it is evident this game was F’d from the beginning. We don’t even have active weather radar at this point and we are in year 3 of the simulator. Simply unacceptable.

I’m not familiar with AMD processors, but yes it should run better with his system
All I know is a 4070 TI is about the same as a 3080 , but he has a 4070 , not saying that’s the cause as he should be getting better performance with DLSS 3 and frame generation

Couldn’t agree more (even looking at main thread, the thread isn’t saturated) and still, CPU bound.

Yep, games terribly optimized, can’t even run multithreading as it’s only using a couple of cores , let’s hope FS 2024 is much better

Hi, i have much the same set up as you. I also experience these jitters on climb out or on finals mostly 2 or 3 these are not shutters in my case only jitter.
This only happens with add on Airports. I have tried flying with add on airports removed, and smooth as anything no jitter. Any one test the same let us know.
I9 13900k, 4090 TAA,FG on, Z790.
I’m no expert on these matters but IMHO having a 9th gen CPU is going to give you a massive bottleneck on a 4090 card
It cannot give the gpu enough frames to deliver a smooth picture with heavy add ons that’s why you get jitters on approach and climb out , it’s not solved by Overclocking although that helps but it’s the architecture of the chip and how it interacts with data transfer to your GPU
Your GPU is sitting there waiting for the CPU and your CPU can’t keep up
I read somewhere that the minimum for a 4080 is a I12600k , having a 4090 would best be paired with a 12900 or 13th gen CPU
It’s about matching your hardware so the less of a bottleneck ensues.
Unfortunately , with MSFS it will bottleneck even a 13900k cpu , but other games it seems not to be such an issue
If you had the money, I would get a 13th gen , preferably the 13900k version , you have a z790 mobo , I think if I had a 4090 I would try and get the best cpu , that’s not being rude so please don’t take it the wrong way, personally I would love a 13900k too but cannot afford to shell out for it and additional cooling that one would need.
Sorry if I sound like some pc guru , just giving my two cents to help solve the issues you are experiencing
My specs are:
12600k overclocked marginally , 200mhz on P cores, and E cores
RTX 4080 FE , runs a lot cooler than AIB cards
1000w PSU
32gb 3600 mhz Xmp1
Z690 mobo
Windows 11
HAGS on , TAA , DX12 , frame generation on

Thanks for your reply. Sorry i made a mistake my cpu is i9 13900k. I am still puzzled.

Don’t use in-game/developer’s mode fps counter. Even steam’s fps counter would work (just to see the actual fps you’re getting). When I first received my system (RTX 4090-7950x3D) I though I was getting 40 FPS. Then I used an external FPS counter and realized that I was getting 100.
