It stresses it in an outdated code kind of way. I’d bet if you took out Duke Nukem 3D and ran it on a 4090 rig and cranked the resolution it would stutter. The sim stumbles over itself putting so many objects into a base engine that originally ran in a muddy weakly textured and shaped world. The very idea of continuing to paint new things into and onto that old ‘world’ by the billions would eventually hit a point of drastically diminishing returns.
That is, of course, a good point. And yeah, nobody needs 90 FPS at full Ultra non-frame gen settings (except maybe VR guys.)
Who knows, maybe the 5800X3D will do a FENIX A320 @ 90 FPS at full Ultra with the new miracle code. 
Does anyone run FSX in it’s native FSX state on a modern 4090? I bet that runs like a scalded dog. 2020 is a finite funnel they keep adding not only quantity but with a heavier viscosity.
Technically even with 2020 we are over-stressing our settings. The 4080/7900XTX should in theory be running at ‘high end’ settings as per the original intent of the sim based on what IS ‘high end’ at the time of release. Some ultra settings like texture resolution are runaway settings that are for things not invented yet unlike say ultra buildings that will hit a capped resolution for those drawn items. Then we beat on Asobo for some of these things unfairly too. And then add things designed by 3rd parties.
Really should take off all non MP third party items and run the sim at hi-end settings to see what Asobo is really at ‘fault’ for regarding performance(if one has a ‘high end rig’ like a 4080/7900XTX/4090 with a 7800X3D or better). Some of those ‘ultra’ settings are for rigs anticipated 5+ years beyond release date.
Very underwhelming much like Arrow Lake and the rest of the AMD 9000 series. Lots of hype and then finally we get the reality.
That said, I think this will be a great option for new builds especially for me moving finally from my Intel i5 7600k. I think that a lot of people who already have a 7800x3d though will stick with that for a bit.
I have also seen today that some early users of the Arrow Lake CPUs have experienced black screens/crashes. Don’t know if it’s a big issue or not. Someone mentioned it could be a micro coding issue whatever that is. Hopefully it’s not too serious. Competition for AMD is good. I don’t want Intel to fail.

You’ll be blown away if you do a 7600K to 9800X3D.
I went from 8700K to 7800X3D and it was a revelation in MSFS performance.

Finding the hardware is the challenge this season. I don’t see a lot of inventory out there yet.
Yes, really hoping so. Honestly, though, it still performs well above its weight with my (now) old 2070s in most games, MSFS 2020 included.
The 7600k has really been a great cpu (got it in 2017, so wow, 7 years old!) especially since I overclocked it to 4.6. My plan is to couple the 9800x3d (amongst other things) with an msi mpg carbon x870e mb, amd 7900xtx gpu and 64gb high speed ram in a corsair 6500x case. I will maybe upgrade to a 5080 gpu in maybe a year (depends on how good the 7900xtx is) when the hype has died down a bit. Going on past history I will probably keep the motherboard for around 5-7 years and just upgrade other components as and when.
Feeling a bit like a kid at Christmas tbh. The anticipation is great. Hopefully, the reality won’t fall too far short of this

I see much interest on this thread in the Ryzen 7 9800x3d but not the Ryzen 9 7900X3d, so I’m going to repost a question I had asked on my thread concerning a new build for VR simming:
Since I was looking at an AMD Ryzen 7 7800X3d before considering MSFS2024’s supposed core usage improvements, I assume that an AMD Ryzen 9 7900X3d would be a logical choice. It has 4 more cores and is a bit faster for almost the same price. Most other specs are the same.
For use with an RTX 4090 I can’t see any downside. Am I wrong?
I went back to a 2023 thread on this topic and found a lot of good info. Here’s a snippet from a member whose opinion I respect greatly. Hope it helps.
I upgraded to a 7950X3D and found that I needed to do a lot of work in Process Lasso to optimize FS20 performance. Once I did the work I’ve been very happy with the results. I posted an extensive thread with test results of my tuning process. Bottom line, the 7800X3D is the ‘Easy Button,’ while the 7900X3D and 7950X3D can perform a little better with some dedication to tuning.
I didn’t want to wait for the 9xxx-series. Nothing wrong with that, though.

Based on the new knowledge of MSFS 2024 from carefully watching all of the dev streams and reading any extra material, I think it probably comes down to 7950X3D being best but really needs good setup with ProcessLasso etc, and 7800X3D being second and a lot easier to manage. 7950X3D could well be noticeably better if you run a lot of external tools.
I’m thinking the 7900X3D is probably going to fare worse due to only 6 cores for the game, while Seb has demonstrated the new sim can effectively use more than 6 cores.
Of course this is all based on a plausible interpretation, the only way to actually know is to performance test this in a range of scenarios on each CPU.
I’m still waiting for the release of the 9xxxX3D variants to see what they deliver. I’ll certainly be considering upgrading my 7800X3D to a 9x if the tests look good on MSFS 2024.

This is true of so many things regarding FS24.

I’m also waiting for the 9800x3d. If an increase of only 8% in gaming performance compared to the 7800x3d will be confirmed, there is the great novelty of overclocking that will lead to much greater increases… I hope
When choosing CPU, there are many factors to consider and it ultimately depends on what you’ll be using it for.
Faster?
I used to think the Ryzen 9 7900X3D would be the perfect entry point for diving into AMD, especially after 30 years of sticking with Intel. It seemed like a solid way to start this new chapter. But in the end I opted for Ryzen 7 7800X3D. As a gamer, it’s better suited to my needs and with the next generation right around the corner (Ryzen 7 9800X3D) going for the Ryzen 9 7900X3D would have felt like a stretch. Ryzen 7 7800X3D just hits that sweet spot for gaming right now.
So, currently, the best CPU for gaming in terms of price-to-performance is the AMD Ryzen 7 7800X3D. It’s an outstanding CPU specifically for gaming, offering top-tier performance but it’s not recommended for multitasking or heavy workloads outside of gaming.
But, we’re all waiting to see if a new king will emerge soon, so it’s better to hold off and see what AMD brings next.

7800X3D Will be overkill for many years to come. Don’t succumb to the marketing for the next generation processors. I genuinely don’t think there will be any observable differences in performance. 9800x3d is likely to be a ~15% improvement from the 7800x3d. This isn’t observable to the end user + no one buys these processors to play at 1080p. If you play 1440p or above and have a 40 series nvidia that is. I have a 4090 with a 7800X3D. I don’t see the need to upgrade personally. So enjoy your new computer whatever it is - I know you would have be blown away by the 7800X3D but all the best with your final choice.

No such thing for this sim.

As usual there is more to it than initially meets the eye. I wasn’t aware of some of those points, so thank you all.
Whatever ends up going into the new build it will most certainly blow me away because I currently use an i9-10900K with an RTX 3080 (EVOC laptop). I got it to work pretty well in VR (Reverb G2) but with the expected compromise in settings.

I get what you say however there are certain cases where extra processor power isn’t needed. In my case I have a ROG strix 4090 OC edition coupled with 7800x3d. I fly on my 1440*3440 ultrawide with everything maxed (including render scale). With FG I get well over 100 fps everywhere. In most cases I render more frames than my 165hz monitor can support. So in my case any other processor is going to be overkill. I guess my case would be different at 4K but probably not by much, as I already said I am rendering at resolutions greater than 4K with my render scale maxed to 200.

Even though I have my 7950X3D and 3090 Ti latency well balanced, and my GPU runs @ 85-90% load with a 4K main and 2K seconday monitor, I ‘feel’ like I’m GPU limited, mostly because increasing LOD and traffic settings don’t seem to affect FPS much (until I get silly with them.)

I currently have a Ryzen 7 7800X3D paired with an RTX 4090 Gaming OC.
For flight simulators, not just MSFS, CPU has always been far more critical than GPU.
If Ryzen 7 9800X3D indeed offers a 15% performance increase, it could be an excellent choice especially paired with RTX 4090, where GPU is already very powerful, so CPU becomes the main bottleneck. A 15% boost could mean more stable frame rates, smoother animation and overall better responsiveness in more demanding scenes.
So, if tests show that new Ryzen 7 9800X3D gives me a 15% performance boost, I will definitely buy it, as smooth gameplay is essential in flight simulators.
I’m also glad that, after 30 years, I switched from Intel to AMD, as I won’t need to buy a new motherboard - that means all the money saved can go straight toward the new Ryzen 7 9800X3D CPU instead.
My motherboard is already prepared for new CPUs.
