I am on beta and I have recently tried two systems:
- RTX5090, Intel Ultra9 285k, 64GB Ram at 6,000, 4GB SSD NVMe
- RTX5090, AMD7 9800X3D, 64GB Ram at 6,000, 4GB SSD NVMe
Each around $7,000! And guess what, none of them performs the Sim smoothly. Sure, the frames can be high, but there are constant stutters near ground and at the airports. If I use Frame Generation, the stutters are at uniform periods (like the picture below) which is very annoying as it feels like a fast slide show, if I don’t use frame generation, the Sim seems smoother but there are still significant stutters at busier airports. I returned the first system to Dell thinking that since the main thread is the issue, it may Intel related, but the 2nd system (AMD) is performing exactly the same!
What exactly do we need to be able to run this game smoothly? It’s sickening that I would spend so much money on a hobby that I love, just to see slightly better performance than my 3.5 years old system (RTX 3090, i9-12900KF, 64GB ram at 4,400, 2GB SSD)!
Settings: Ultra, TLOD 300, OLOD 200, TAA (as DLSS results in blurry screens) …

Fly GA. Starts to run
Jokes aside, I run pretty much the second system, except with a 5080. I run at 1440p and with TLOD200 (if not flying VR), anything more couldn’t handle complex scenery stable (PG/big handmade airports). Pretty locked at 60fps vsynced. Also not much mods or any other external 3rd party stuff.
Currently your only option is to lower settings or use dynamic settings with target frame rate 5 above what you want.
Just because a slider in the settings goes all the way, doesn’t mean the (currently) most powerful systems will run it smoothly.
PS: I only fly GA.

Yep! So, the answer is basically No! No system will run this Sim smoothly and the difference between the older and newer systems is marginal, so don’t waste time and money.
If you want the Sim to be smooth:
Don’t fly extravagant 3rd party planes like Fenix
Don’t have ultra settings
Set TLOD to 200 or less
Don’t use any AI plane program
Don’t fly to busy airports
.

Don’t do airliner stuff pretty much! Just use the Sim for bush flying in no man’s land areas! haha! That’s sad.

Even that doesn’t work. I was getting the same stutters (not quite as bad) in Mongolia. At altitude, lower down, at simple airfields. There isn’t really anything here but terrain!

In a nutshell, set it up correctly.
What is the refresh rate of your monitor? In other words, what FPS are you trying to achieve?
I recorded this quickly for myself the other day but it’s useful to demonstrate that this sim, on a system like yours, can and does run perfectly smoothly. FWIW this is on a 9800x3D, 4090, 64GB RAM. I am using the full suite of AIG models injected into the sim with BATC, and every setting possible is at its max with the mod we’re not allowed to mention raising my TLOD from 200 on the ground to 600 between 2000 & 4500ft. It is in 4K, with the frames locked at 30 in the user.cfg file and FG doubling it to the 60fps that matches the refresh rate of my monitor. Finally I use DLAA as that is the best AA solution.
In terms of add-ons I’m using BATC as mentioned above, Bijan’s Seasons Enhanced, the Fenix A320, GSX and MamuDesigns Marinas.

I have it set at 120hz, TAA, VSync on and cap fps at 33% of screen… So basically, trying to get 40 fps. You would think that’s easily doable with such system! Nope, it’s still stuttery at the airports and near ground.

Can I suggest you try setting it up like mine and giving it a try.
I would set your monitor to 60hz refresh rate, set a frame limit of 30 in the user.cfg file and turn frame limit off in NvidiaCP. Turn VSYNC on (not fast) in the same place and turn it off in the game.
Once you get it smooth at 60fps you can ramp it up from there.

My PC is weaker than yours and I fly with third party airports, Fenix and ATC/Traffic add-ons, and I get a smoother performance then you appear to do. Oh, and I fly with Ultra settings on a 4K 144hz monitor and a second monitor which is not 4K but HD.
Therefore I can only assume it is something your end.

Thanks. But I see consistent stutters on your video (the same one I see on mine with frame generation on), it’s very consistent at a certain period (time frequency), that you have to pay attention to notice but I notice it and it bothers me. Try to focus on tiles when the plane is turning you will feel the stutters.

The only stutter in my vid is when use the POV toggle on my stick or yoke to pan to preset camera views. Granted that is annoying but is clearly down to off-screen caching. I’m away working at the moment but when I get home I’m planning to reduce that setting to medium and turn off the rolling cache which I believe will likely fix it.
The point is that aside, the whole experience is smooth. If I use the mouse to pan around rather than the POV switch it is smooth as silk.
Edited to add, you also have to remember this is recording in 4K and 100mbps as well. I omitted to mention I also have a 1GB fibre up/down internet connection too which very much makes a difference.

“Is there actually any system that would run this Sim smoothly?”
Yes there is. My rig runs the game smoothly, without stutters, great scenery, no issues at airports, very enjoyable. Play regularly. Never had a CTD. Never had a problem with game updates. Yes career mode is a laugh but I still enjoy it.
Intel i7 6700, 24gb ram, RTX 4060ti 8GB, three 27in 60hz monitors running at 1440, 75 mbps internet, mix of medium/high settings with ultra clouds. Using TAA with frames limited to 30 with nvidia FG giving me an almost constant 60fps. Dynamic settings set to 30.
I was thinking about getting a modern fast cpu, a 5070 and a nice big 4k screen but reading the comments I’ll stick with what I’ve got and save my money.

FWIW I think you’d notice a big difference, but (and this is personal opinion obviously) I wouldn’t touch any GPU with 16GB of VRAM or less
I’d waited for the 50series to release before upgrading my machine and when I saw the paltry amount of VRAM the 5080 had onboard chose instead to go for a 4090 (which is a stronger card anyway). I’m very glad I did.

Fully agree with you regarding the GPU. I think to have a relatively good experience, you should have a GPU with 24GB Vram (so basically either 3090, 4090 or 5090). Most people complaining about the Vram have lower memory.
I will try your suggestions and report back. I love the quality of TAA so DLSS (DLAA) is not too bad but definitely not as good. But if I get a smoother experience with a little loss of quality, I would at least try to get used to that. The 5090 GPU seems to be doing almost nothing in my system (it’s way too green ;)) would you suggest higher render scaling?

Remember DLAA doesn’t scale, it renders at the your full resolution and I find it to be the better option. I don’t see any of that shimmering that TAA sometimes produces.
I maybe missed what resolution you were playing at. That GPU wants to be pushing 4K as a minimum either natively or through render scaling. Using DLSS with that card is pointless anyway as it will simply be reducing the load on the card.
Oh, I just saw. 1440p. I suspect that is your problem. As a minimum you should be using render scaling of 1.5 with DLAA or TAA as your AA option and every setting absolutely maxed out (except airport traffic if you use 3rd party and I set road traffic to medium as I think the roads look silly on anything higher)
The 5090 likely out powers every CPU on the market so you need to get that thing working to balance out your system. If the GPU is sitting around waiting for the CPU that’s when you start to see stutters. FWIW both my CPU and GPU tend to be around 60% usage with occasionally spikes on the CPU as I am pushing it hard.

Yep. No scaling with DLAA.
I tried your suggestions, and I think I can settle with TAA, VSYNC on at 33%, monitor at 120hz. I will try higher render scaling (I have it now at 110%). But overall, it’s not too bad with this setting. I just can’t handle the DLSS/DLAA ghosting effect, blurry screen (with little movement) and also all the line edges (i.e. on the wings).
Thank you very much for your input. Hopefully the CPUs will catch up with GPUs soon and then we may have a full-on smooth experience.

Constant (each 2-3 sec) stuttering. Try it in VR + VFR where you look out of the cockpit frequently and you will be sick in 3 minutes
I have spent 16000$ on 9800x3d, 5090, 64gb + 4dof motion rig, + G1000 monitors, moza ab9, pimax crystal light, bass shakers, pedals, hubs, etc, etc..
And i can not get it run smoothly. I fly VR only and this sim is too heavy for any consumer hardware (tuned and optimized) currently available , especially in VR

I don’t know for sure as I’ve only ever had a 60hz monitor, but I’d be very confident you could cap your frame rate at 60 in the user.cfg file (let me
Know if you don’t know how) and turn frame gen on at x2. Turn VSYNC ‘On’ in the Nvidia Control Panel and disable the in-game VSYNC. Finally set your render scaling to 150% or 1.5.
I suspect that would improve things considerably and happily give you 120fps which your system is easily capable of using FG. I’d be really interested to see how that would be for you, I suspect it would blow you away to be honest.
You have a 5090, time to let it fly!!

“What do we need to be able to run this game smoothly?”
Better optimisation techniques from the developers, they’ve always struggled with LODs so they need to get a grip on that, they’ve struggled to maintain DX12 to an acceptable standard so they need to continue working on that, they’ve struggled with VRAM issues even though they claim it’s “fixed on SU2 beta” which is very clearly and evidently is not.
It shouldn’t be up to us to lower settings or buy a new GPU as the Devs said during a Q&A, it should be up to them to better optimise their code.

Z790 / i9-14900KF / RTX 4090 / 64GB DDR5 RAM @ 6000 / PCIe Gen4 NVMe M.2 SSD / 27" 2560x1440p @ 180Hz / A very debloated Windows 11 that I only use for gaming and I always keep drivers up to date.
I run everything maxed out aside from having render scaling at 120. It’s peachy on my end (currently in the SU2 Beta). Looking around with TrackIR is very smooth.
