Officially 1 month of using MSFS with SU2, and it has become the Flight Simulator I've waited my whole life for. It has surpassed MSFS 2020 on every level in terms of performance and scenery (now - it was horrible prior) but I've learned a few lessons along the way that I'll share - and remember YMMV.

1) AMD 9900X3D CPU / MOBO setting. If you have poor performance in MSFS 2024, go into your BIOS and clear out all of your overclocks and tweaks and do a "Load Optimized Defaults. I'm running the GigaByte Aorus (870E chipset). This setting puts in a generic overclock to 5.5 GHz. You want to do manual over / underclocking, then you do so at your own risk. The more I experimented, the worse the performance got. FS 24 is a unicorn, it seems, and a very fragile one at that. So your setting that makes CyberPunk scream, makes FS 24 a stuttering pile of frustration.

2) I'm running 64GB of EXPO1 memory (or XMP 1 - depending on your memory). The only other setting in the BIOS besides Optimized Defaults is selecting this. Memory is running at 6Ghz. Be careful with Memory tweaks! MSFS is very fragile. EXPO1 and XMP1 give no issues. You start messing with it after that and it will crash. Trust me.

3) DO NOT use AMD Gaming Optimization! Gaming mode reduces the cores from 12 (24 vCores) to 6 optimized cores by turning off SMT. This may very well work well for other titles but I've tested MSFS 2024 with Gaming mode (SMT off) vs non Gaming Mode optimizations and by far non-Gaming Mode is better. You also see core usage at 100% with Gaming Mode on vs barely 40% with Gaming Mode off. 

4) If you're getting CTD blaming anything 3D or NTDLL, take out the overclock in your video card. I am running a Asus 4080 and had a stable overclock in either Nvidia App or MSI After Burner which works fine in everything else but MSFS 2024. As I said above, MFS 2024 is very fragile. I was having random CTDs and took out the overclock. I've flown pretty much every day for this month and no issues.

5) Verify that your video card firmware (not Nvidia driver) is up to date. There was a bunch of firmware updates required by my card (Asus Crate updates my card) but I didn't know and I was getting bad sound crackling and pausing every 5 - 10 seconds in both '20 and '24. Did a firmware upgrade and they went away. I actually built a whole new computer and still had the issue so I narrowed it down to the video card which was the only part that I kept between rigs. 

5) You've probably already figured out that FS 24 is hugely reliant on VRAM. Most times FS 24 recovers once you see the warning, but every now and then it doesn't and the sim becomes a stuttering mess (cough FSLabs A321...cough). If it doesn't recover to normal framerate after 30 secs max, you're gonna have to restart - and a full reboot of your rig to be safe. Which sucks after you sat at the gate for 45 minutes loading pax and setting up your flight deck.

6) I'm running all settings on Ultra or High. 200/200. Raymarched shadows off. Rocks and fauna off (I'm flying heavy iron. If I see rocks or fauna then I'm having a really bad day). 

I'm sharing this because FOR ME (again YMMV) FS24 has gone from a nightmare to a dream. And some of that nightmare was self inflicted by me. So now I know the rules of FS 24 if you're having issues the above is a good starting point. My only fear is that FS 24 is performing so well and it is indeed so fragile that I'm afraid a driver or update will break it!

Either way, I hope this helps anyone who is still having issues with MSFS 24. I've officially deleted 20 this week. Oh MSFS 20 - I hardly knew ye!

You got any opinions on how to fix the sludge looking terrain? 2020 was crisp but 2024 is absolutely terrible on my rig. I’m running 500 mb/sec.

Well written observations. I've been running my rig with similar settings since I built my rig and installed 2024. The only thing I do different is that I use Asus AI suite to control my cpu overclocking instead of my BIOs. The reason being I don't want my rig to constantly run at 5.5Gs. I want it to throttle down if I don't need to run my cpu at higher speeds. Only thing I set in my BIOS is the memory XMP to on and the setting to turn on the core parking feature.

There was a software engineer that help develop windows that would come and show you how to setup up windows to run Flight simulator for a fee. He passed on but he taught me quite a bit on setting up my computer to run flight sim, what to do and what not to do. Alot of folk's issues are that they don't know how to setup windows properly to run flight sim. Once you get windows running efficiently, flight sim will run efficiently. I rarely have CTD with 2024 or vram issues. (Only when I test the beta's). But I'm more than happy with the way 2024 runs on my system. Crisp clear terrain no studders and great performance. But again, nice observation you wrote. I have not deleted 2020 yet because there are some things I'm waiting on to get released before I do. 

The real reason is you need a 2000€ PC to run it smooth.  Under that impossible. 2020 will perform better

True only for those who do not know what all those things are for listed under "customize graphics options". Sadly, nowadays the vast majority of the users. Just a hint from my side: rumor has it that using "medium" or even "low" might improve your performance on medium to low end builds. But as I said, maybe it is just unconfirmed rumour...

Who wants to run graphics settings at Medium or Low?

Those who cant afford a rig suitable for high and ultra? I mean, there is no free lunch, if your budget doesnt allow for a high end rig, you have to get along with reduced settings. 

It is a idiocracy of todays time that even those using a potato still think they are entitled to run each and every game in "ultra" settings. They are not. End of the story...

Thanks much. Could you please share / snapshot rest of your graphics settings.

Even in medium or low it won't run smooth. At big airports. With average hardware. This game is just badly made and only working on expensive hardware.

Not true. I consider my system mid range. I'm not running the latest expensive hardware, but I'm able to run 2024 fairly well. I know my system limitations and setup 2024 accordingly. I also know that I can't run 2024 settings all at ultra, so I reduce graphic settings to high in most cases. Just because you have a $2000 system doesnt mean you can run 2024 at max settings. Use common sense and set your system up to run what's best for your system and not what you think it should run at because someone else can.

It's not running 5.5Ghz constantly, only when demand requires, correct?  I use PBO with a curve optimizer at -20 and only on rare occasions does 2024 ever demand anywhere near that clockspeed with the native rate locked at 50FPS.

If you set up your cpu clocks for 5.5 in BIOS, it will run at that speed constantly. I use software to control my cpu clocks and rarely do my clock speeds go over 5.0. My max is 5.5 but 2024 has not required that higher clock speed for me yet. Even when running multiple addons in the background.

I'd love to see vCore with that set to run 5.5 constantly.

Without knowing your specs, simply having 500 Mbps doesn't mean much because it could well be like driving a Toyota Prius on the Indianapolis 500 track and complaining that your car is not achieving 200 Mph 🚙

I have highly crisp textures out to the distance:

1. Ensure you have Dynamic Settings off - Makes the terrain look terrible to achieve more performance.

2. TLOD / OLOD = 200. Even dropping it down to 150 blurs the terrain noticeably. Droping the settings seem much more drastic than '20

3. Ansiotropic Filtering to 16 if your card can handle it, no lower than 8

3. Nvida - Texture Filtering = Clamp

It's running at 5.5Ghz constantly. I'm staring at it in Gigabyte Control Center while the PC is idle (5% usage) - Temp 46c. Max Temp running FS 54c. '24 doesn't demand high CPU usage so its only around 45% most of the time. UNLESS you turn on gaming mode where you'll get 100% usage for less frame rates.
