I have a 1250W PSU. Asus Maximus formula V mobo, Intel i7 8086K 6 cores 6 threads, 4.6Ghz turbo 5.
My Cpu runs at between 24-40% only on 4 cores, the rest even lower ( I thought this game is Cpu bound) My Graphis card RTX 2080 8GB is running 79-95%. I run most values at ultra in 4K downscaled to 70%, view distance 200 on all sliders and I have at Arlanda Sweden runway 01L around 35-37FPS with the FBW Airbus. So of what I see My graphic card is the bottleneck, now the question is do I need a faster graphic card but it will be ok with the same ammount of ram or do I need to go for the 3080 Ti or 3090 whenever they become available ?
You don’t need to change your graphic card. Just upgrade the CPU. And even if the cpu is not 100% you can be bottleneck.

I would wait for the sim to bring out the performance improvements and DX12.I am on a 2060super and patiently for cards to be back in stock.If you plan to upgrade the CPU don’t expect a big boost.The GPU is possibly already the bottleneck.
You can have more vram and if the card is slow it won’t do much.3090 is a good upgrade but are you doing anything else heavier than msfs that requires that vram?

More memory, without question. Flight sims are VRAM hungry and that will continue to grow. The only real choices are 11GB, 12GB or 24GB. I have an 11GB 1080Ti, and it runs the flight sims of today very nicely. However, there are some that push the envelope above 11GB. I used to run everything in 4k and quite enjoyed squeaking out 30FPS. Now I run 1080p at around 40-50fps and up, and I can forget my settings.
If you think your 2080 is inadequate, try this test. Turn down the terrain and object level of detail to the LOWEST setting. Then tweak everything else until you are happy your frames are at their peak. Then work the LOD’s up until you get the FPS you desire (mine are at 60). I also turn off shadows because I like to fly in low light conditions at dusk and dawn. This, and running 1080p will take the load off your card.

Hmm, ok. Can you please detail that a bit further? How can a CPU be a bottle neck if its not used, I would undertand if it was Throtling or something but here is not passing 40% IN P3D its running over 68%. If I disable hyperthreading it will go at around 60% on alla cores
Here is the thing you don’t need 11gb 12 or even 24gb vram .If you are on 1080p not running anything complex you don’t that amount of vram. If you are running medium/high you also don’t need that amount of vram.Either way most people are on 1080p.
If you are pushing maxed settings running at a higher resolution its a must oh and VR.
When the FPS counter says Limited by GPU you have too much to draw. When it says Limited by CPU you have too many things (objects) to handle. When it says Limited by… you will notice that the frame time (12ms for eg.) is the highest for that component. So CPU frame time could be 14ms, and GPU frame time could be 12ms, so CPU is the bottleneck in this case. MSFS is different from P3D in that it does a lot more CPU work and less GPU work.
True for MSFS. Not so much for DCS. 
As for now Im happy with the frames, Im thinking ahead for the PMDG releases, they usualy cut the frames in half from whatever you have with the default aircraft, I may take the advice to wait for the DX12 maybe DLSS, Im just trying to understand why it uses my GPU more then the CPU. In Grand theft auto 5 I have the same thing the cpu is barely at 40% with 35C and GPU is working like crazy. Other sims as P3D maxes out THE CPU.
I would like to keep my settings as they are, maybe even go full 4k and Ultra on all settings.
MSFS cannot use all the threads and cores of your CPU, but those cores that it uses are maxed out. This is CPU bound even though the full CPU usage isn’t 100%.

The CPU activity is also coming from the network components. Try turning off all network features as well when you test. However, you may not like how it looks.
All the airport objects, people, cars, air traffic, that’s all CPU heavy. I have 1 guy at the airfields just for fun, but you don’t even need them.
That is true for FSX and 32bit P3D, P3DV5 runs all cores on maybe 60% and MFS2020 as I said 4 cores run around 20-40% and the rest 10-30% there is not one maxed core.
My CPU runs only at max 20-40% GPU is overloaded 79-95% sometimes 99%
My CPU never passes 43% on any of the cores and keep a max 42C cool
I should also mention that the new web assembly modules are run on LLVM’s (tiny virtual machines). If the aircraft you fly has a lot of glass instruments this will add CPU. Plain steam gauges are lighter.
Again my CPU seems not to be strain, In the entire topic im talking about my GPU…
No, my GPU cranks away at 100% no problem; they are designed for that. CPU starts to degrade at 50% and is basically maxed out at 85% and up. Those numbers are fine.
Since my CPU seems fine And the GPU works all the way to 100% im not afraid of the GPU braking, rather than If i change it and to what I will gain more frames
I think you can get what you want from your current card. Try my experiments. Took me awhile to get the right mix. I have Ultra for most of my settings.
Now, that’s not made pretty (NOT Ultra), but you can achieve that with your card.

I give that a try, thanks…
