Yesterday some new hardware arrived. 

Asus CROSSHAIR x670e, Corsair Vengeance 32GB 6000mhz 36Lat, AMD7900X (64MB L3 Cache +12MB L2) and Corsair waterblock (for my custom water-cooling at 2x360mm radiators). 

I use this mainly in VR with Varjo Aero at 37ppd (almost 4k).

Sim settings: DX12, Almost everything at ultra, vol clouds at high, ambient occlusion at medium, terrain vector data at high. TLOD200 (even 250 is possible without a single stutter) and OLOD 180-200).DlSS at quality.  

Well, I'm flabbergasted this was possible with FenixA320 at EDDF Asobo bad optimised airport with AIGAIM at 60 percent I get 35 Frames at heavy rain and OC clouds and SUPER SMOOTH Experience. I mean, panning, taxiing takeoff all butter. Above FL030 (3000FT) almost everywhere 45 to 50 fps!

I'm now GPU bound (97% at 3090). My AMD cpu 7900x sits at roughly 30%usage and some of the 24processors are even almost not used.

I have undervolted my cpu (PBO2 with -25 curve optimised) , temps are average at 65celsius and variating between 40 and 80 Celsius. Clockspeeds go up to 5.5GhZ but mostly below this (between 3.0 and 5GhZ). 

Windows 11 22H2 HAGS ON. 

This is a huge jump up from 10900k! 

I can recommend using AMD as probably the high caches are really helping out.

I am waiting for a 7950X system to arrive with 6000mhz DDR5. The L3 cache is what swayed me over the new 13900K. 
Plus I’m gambling that I can switch out the 7950X to a 7000X3D one when it arrives with even higher L3 cache. 
 

First time using AMD for two decades for me, and it looks promising, your results look really good. How is it in 2D? 

The AMD X3D chips with the much larger cache is definitely the way to go.  The benchmarks in MSFS have proven it time and time again, and not by a small margin.

I have also been Intel for 20 years, but their small increments are not cutting it.  I was looking at swapping out my 12900k for a 13900k, but I have shelved this idea for now.

Interesting Ian. I'm in a similar boat but thought that the 13900k looks likely to give more fps than a 7950X based on what is known so far. From what I can see the 7950X barely performs better than the 12900k. Are you basing your preference over the 13900k on smoothness (because of L3 cache) as opposed to higher fps? Where did you see that the 7950x offers a smooth or better experience in MSFS?

I'm asking because I was considering the 7950x but felt a bit disappointed in the benchmark reviews in terms of fps. By the way I plan on also getting a 4090 and using 4K. 

I look forward to hearing more of your rationale behind your decision. It might sway me in my decision too. Cheers.

Exactly this. It will give high enough frames in msfs without fighting over an extra 5 or so, but because it’s L3 cache is higher it should be (and seems to be by the op’s experience and also looking at the X3D cpu) will be way smoother. And that’s what it’s all about for me. The smoothness is what creates the feeling of flight. Of course higher frames help, but if we can get to 60 with nothing ever dipping below 40, then I’d rather have smoothness than more fps. 
 

One more thing that swayed it for me is longevity; these new AMD motherboards are going to have support for 5 years. Intel is non committed with such talk. 
 

oh and this one is a bit of a gamble, but I’m pretty certain that it will support AMD’s new X3D cpus in January, and if the old 5800X3D is anything to go by, these cpus will be the king in MSFS!

An interesting thought I just had.  I saw HAGS is mentioned as on by @mpo910  I need to revisit HAGS as wells as resizable bar.  Not sure if the 2nd is even supported.

I habe them both on...but the resizeable bar I do not know either. 

Important is, if you get extreme latencies then try the in sim depth and motion (if I recall correctly) turning off

You've given me good food for thought there Ian. Thanks.

In any case, I may be forced to wait a few weeks for my new build as everywhere seems currently sold out of 4090s. 

Let us know how you get on with your new system when you receive it!

Local shop near mine (also deliver, good reputation place) has a few left:-(U.K.)

My OC i5 9600k and 3070 still a good combo!

Depends what you’re looking for. Some say their old Old Ford is a good car, some want a brand new Ford. 

I am also thinking about going from 3080 to 4090, but not now. They are really expensive, for that you have to replace the PSU and the case. 

What would be interesting as well would be to compare (with an RTX 4090), the difference between a 7950X, a 7900x, and 7600x in MSFS, especially looking at the 1% lows (aka the smoothness barometer) to see how much difference the L3 cache makes in each chip (as they differ in quantity). I'm especially curious what the difference between a 7950x and 7900x is.

Oh you can crank that bad boy up to 39PPD just fine. Also have you noticed the stutter? If you fly on cloudy days it’s terrible right now. There is an issue with the Varjo and 4090.  If for some reason you swear you don’t have any stutter then join the discord and help Varjo out. They are being very responsive.

I am on a 3090 and have no stutter(s). Only if I crank the settings to high (LOD or something)
