When this sound crackling happens to me, I visit the Sound settings in MSFS and turn off the stupid  selection of use windows default for sound and mic. And I make sure that both sound and mic use exactly the same choice, whatever that choice may be. And the problem goes away completely. 

Not here unfortunately.

How much VRAM is the A350-900/1000 and A380 actually using at 4K 60 fps today ?

I have no idea as I don't fly either of those aircraft, sorry! Only had the 5090 working for 2 hrs so far, but my first impressions are that it will do 60fps (smooth frame times) in 4k TAA Ultra settings in all circumstances with pretty darned good 1% lows.  And that's with TLOD 500 and OLOD 200 forced. The fluidity and smoothness combined with exceptional scenery as far as you can see, are for me, using head tracking in low altitude high speed use cases, absolutely worth the price.   In not so Uber demanding circumstances it's even operating more quietly, and using the same amount of power, as my old 3090 did producing half the performance.  I've not seen it use more than 15 of it's 32gb VRAM in any use case yet, but I'm sure I can push that!

Two questions....

AMD 7800 X3D or Intel i7 14700KF?

My brother is thinking of buying a PC with an Intel i7 14700F CPU (similar specification to the one that I was thinking about in my opening post). Would he be better choosing an AMD CPU instead? He does not use flight simulators, but he would be using it for stuff like Elite : Dangerous and X4 : Foundations (and maybe some first person shooters). He would be running everything at 1080p resolution. Do the AMD CPUs stay cool better than the 14th generation Intel CPUs?

This is a Ford vs Chevy question.. you will find fans of both..  I went with the config that Jetline uses, Intel..  https://jetlinesystems.com/computers

Like I said, go with the cheapest of those two CPUs and put more into GPU.

My AMD 9950X3D runs at about 24-30% utilization and my GPU 97-99% utilization.

Spend the money on the GPU as that is where you’ll see the most benefit.

Not sure that is that simple... you are looking for a balanced config.  A gpu will run at 99% if you choose unlimited fps.  Average cpu load is a misleading number..

Your performance tracks… I have a 4090 and 9800X3D and get 55 native FPS with everything maxed (110FPS with FG) and with MSFS auto FPS I get TLODs up to 800 while flying. I’m “only” using 32GB of main system memory in my system. So my next consideration is 64 as I load up on add-ons. 🙂

Here is a comparison btw the 7800 and the 14900K https://www.youtube.com/watch?v=7KZQVfO-1Vg

It seems to put the 7800 slightly ahead and I assume the 14700 will be a bit further back. Ryzen tends to be a lot more efficient as well.

ED will probably run on a potato it is so old now.

I cap at 60 fps to match monitor refresh.  In terms of MSFS 2024, it is heavily reliant on GPU side.  Capping the FPS will not increase CPU usage.  

In other platforms like P3D, balance is important because you’ll run into batching issues (floating terrain and or AG eventually stops rendering).  But MSFS is entirely different graphics pipeline.

TAA = 200, which is max SSAA so that’s the primary source of GPU usage, but it’s also the best visual quality and will be the most important setting if running 1920 x 1080 (it will need highest quality AA).

Where do you set this?  In the sim, or nvidia Control Panel?

I have been comparing to my config which is an i7 14700KF/16GB RTX 4070Ti Super combo.  This was the Jetline config last year, and works very well for me, but the 4070Ti is not really available anymore..

So for a 16 GB card, your options would be 5060Ti or 5070Ti... If you have the budget, I might stretch for the 5070Ti..  More money, yes.. but not over the top expensive.. 😉

Note: Whatever you choose, do not get the 8 GB 5060Ti card.. no idea why they are even selling that version..

I have a 4070ti Super, paired with an i7 12700kf. It's a great card. In the UK a 5070ti will be nearly double the price of a 560ti but it's also a great deal more capable...

In MSFS 2024 under graphics section, just move the TAA slider over to 200 (Asobo have a hover text to the right stating anything over 100 switches to SSAA).  I run native 3440 x 1440 so TAA = 200 is like running 6880 x 2880.  The visual difference IMHO is night and day and so is the performance hit unfortunately.

But be warned, today I managed to hit 29GB VRAM usage for a flight from EGLL to LFPO in PMDG 777 with a host of add-ons (Orbx, GSX, Navigraph, Simbrief, etc.)

Here’s something I noticed last night about the audio stutters in MSFS2024.

I had a few smooth flights over LA with no issues. Then I exited the sim to add a scenery package. When I relaunched, I immediately got audio stutters in the menu. I loaded into LAX and the stutters were back. I exited again, relaunched, and still had stutters. After a third restart and waiting a few minutes, the stutters were gone.

Based on this, I think the stutters are tied to the streaming server the sim connects to. Each time you launch MSFS, it connects to a different Azure server. If the server is under load, it can cause delays in data streaming, which leads to audio stutters or static, even if your FPS is fine. Restarting a few times can eventually connect you to a better server and smooth things out.

Not related to drivers, BIOS, or in-game settings in my case. Just a possible server side issue.

Absolutely agree ... I was mistaken, I managed to top 30GB VRAM usage but at the options screen not really in flight (Green MEM is GPU VRAM):

And 29GB:

This is the TAA = 200 setting:

I'll post EGLL to LFPO video later with all the data logs and RTSS overlay.  I'm still very rusty with PMDG 777 (couldn't get the SimBrief flight plan to load into FMC, see it in FMC and select it but just doesn't seem to load).
