Yes, same here when I experimented with that resolution. I could run most places just fine, but there were some bigger, busier airports at that resolution that were a little stuttery, so I decided the resolution wasn't worth the tradeoff in performance, especially when 4k looks so good.

100% agree with that. For me the difference in image quality wasn't significant enough. 4K with DLSS + either DLAA or DLSS ultra quality is perfect (haven't decided which one is best yet). And hey - I can finally hear the Fenix engines spooling up to TOGA thrust over the 4090's fans!

There is no CPU on the market that can handle MFSF today

So pull out the crying towels, because I do not recall a new MSFS version in the last 40 years that didn't totally stress the goto power-CPUs at the time of release.  Much less two-year-old CPU's.  I am saving my next build to coincide with the 4th anniversary of the 2020 release, and beyond the best CPUs that might be available, new two-year old model 4090's alone are in the $2K range????????  I might save $$$ and go to Greensboro and go splits on an off lease 2019 Hondajet.

I'm saving up $$$ for rebuilding my computer completely in order to liquid-nitrogen-cool the CPU 100% of the time! It's important to keep that mainthread nice and cool! 😄 This way I'll hopefully be able to have 100% AIG traffic at KJFK and still be able to break the TLOD 2000 barrier.

This is what I alluded to in my post. They are redesigning the server-client relationship so that less content has to be downloaded to our computers for the sim to run. This is not changing the "whole architecture of the sim" it is redesigning that part of the architecture. This should help with aspects of performance, launch time, for example, and we may even see some frame-rate increase, depending on how they are handling the server-client interaction. However, the core of the architecture is not changing; the CPU will still be doing the majority of the work. I think it has to be this way because a great deal of what needs to be calculated is not graphical in nature and is more efficiently done on the CPU. What would be nice is if they can manage to better distribute the work among the cores so it is not so main thread intensive, but this has been challenging for every sim. I think the same conditions will apply under 2024 and this means the best decision is to focus on the best motherboard and CPU. However, I am still waiting to purchase my next rig until after we see the 2024 in action and I can confirm this.

Absolutely. DX12 is still in beta and has been since SU10 in 2022. So it seems that they're struggling to implement it fully. I've been running DX12 ever since it was available, and I'm a staunch believer that it improves multithreading. It needs to improve more though, for performance to improve, as you mention. 

I don't expect much in terms of performance improvement in 2024 to be honest, but I don't mind being positively surprised. 

During the recent years, Intel and AMD seems to have hit the CPU frequency ceiling and opted for more and more cores and threads instead. Which probably does not help much in the flightsim setting. 

I find my 4080 is more than adequate for 60FPS 4k ultra settings and LODs at 200 (I still haven't tried the auto LOD tools yet). 
The GPU runs at less than 50% utilisation at these settings, cool and quiet, which is great, but as people say, it is now the CPU that holds things back and causes hitching occasionally, when the threads top out at 100%.

I have gone from 12900k to 13900k, then to 14900k with a small increase each time.  12900k to 13900k was about 8%, but 13900k to 14900k was only about 3-4%. 
But I still tend to max out on two threads at 100% while the rest are 40% or less.  This is in DX11.

The key to this is for Asobo to concentrate on more multi-threading, which of course they have promised for MSFS2024.
Most people now have 8 cores or more, so I hope they can put I/O on one thread, AI traffic (a well known performance killer) on another thread etc.  I'm sure people get the drift - let's hope they do!

I, by any means know nothing about the “MainThread”, “Multi-Threading” jargon. I am not an FPS chaser by any means. My specs below give me a solid FPS of 40-43, with 50% AIG AI. I have capped my FPS @ 43 (RivaTuner), in-game Vsync “OFF” (NCP only), mostly in-game “Ultra” settings including “Clouds”, DLSS “Ultra Performance” (whatever it is called). I have to admit that I am using the “AutoFPS” app as well which by the way seems to do a great job of real time adjusting the TLOD ( around 600 @ highALT. - MSFS setting 200) and OLOD (around 20 - MSFS setting 100). The clarity of the outside scenery is breath taking!  All in all my FPS of 43 seems to be my “Sweet spot”. I am a Happy camper, and my system seems to like it too.

Well yes, that's what the second link was about. A new flight aerodynamics system that is multi-threaded, taking a lot of work off a single core, thus massive performance improvements. So they are changing how the sim is loaded and how the flight model is computed. If you ask me, that's basically as close to new architecture as you can get without a full rewrite. But yes, the sim will still probably benefit from a good CPU. Hopefully though, you won't need the best of the best CPU to get good performance. I'm expecting this new sim to not only look better, but run faster than 2020, on the same hardware.
