I'd be interested in what addons you're using (especially airports/scenery). With my 3090, I9-12900K, and a gigabit internet connection I don't have much to complain about, but the stutters I do get are 99.9% either related to addon sceneries not being properly optimized or some issue the sim has loading in large sceneries. As an example, I fly in Chicago often and always get pauses when Drzewiecki's landmarks and KMDW load in for the first time. I'm wondering if the DLSS frame generation can account for a 2-second pause caused by gigs worth of textures being loaded all at once because something, somewhere, isn't properly optimized in the addon end of things.

Can you confirm that you can get at least a solid 60fps (i know you quoted higher above) with 400 LOD with/without DLSS3?

100%, even with TAA. Guaranteed. You can use frame generation with TAA or DLSS. I use it with TAA.

What traffic you’re using ?
What are your performances with fenix + big payware airport + traffic + bad weather.

My system based on the 13900 and 4090 is due mid-December.  Can’t wait to get things going around my holiday time.  Thanks for the encouraging results Ian!

i7-13900 or i9-13900, may I ask?

Kind regards, Michael

Michael, it will be the i9-13900kf.

FSLT models with the msfs live traffic system. 
payware airport with CJ4 was around 50-60 fps, which doubles to 100-120fps. 
Haven’t tried fenix yet, I don’t normally fly those type of craft, but I’ll give it a whirl next few days. 
 

weather has negligible performance hit, didn’t really affect my 3090 and same can be said for 4090. 
 

PS even if maxed airport addon and all traffic and heavy aircraft addon, it were still pulling 30fps, that doubles to 60 fps. So it’s still a WIN in my books! We’ve never had it better…!

SU11 definitely provides a smooth experience for me along with running he process at high priority.

I'm still having issues with the sim crashing whilst loading a flight, traffic and ATC, FSLTL and Littlenavmap though.

I just put in the i9-13900K running with the 3080 and couldn't be happier. Runs hot though so do need to put a order for a bigger AIO. Keen on the 4xxx sometime next year.

Let's put it where the goats can get it!

• Fenix is fine
• T-LOD 400, all else ultra is assumed
• RT Online Traffic & Seasons active
• Into FT's KLAS if you have it or a few other suitably demanding ARRIVAL airport, and that matters, the arrival part.
• Video this if you will and capture the last 10 minutes to touchdown with DevMode's Framerate OSD on or better yet use CapFrameX. 

Obviously if the machine is 100% immune to all of the various causes of 'stutters' this is truly new territory if able under the above conditions.   

Does G-SYNC make that much difference? Im running the same specs but still stutter in the fenix at most airports - albeit Orbx ones, with T-LOD at 100, VR still isn’t that great either.

cool, I would expect nothing less from an $8,000 US pc setup.

Yeah, that’s kind of what I thought at first, also. With that kind of setup, for that kind of money, I would almost expect to feel the wind in my hair in the Wright flyer.

To be fair though, the same $8000 PC may perform pretty mediocre when running the other competing civilian simulators.  MSFS is using everything this setup has to offer, something the competition isn't (ie. the competing civilian simulators cannot take advantage of DLSS 3, nevermind DLSS 2).  I think with MSFS, and a top of the line PC, you do get an experience that is unparalleled for a civilian flight sim - hence I do agree with the premise of the title of this thread.

I remember when John Vennema, the President of Orbx, stated that P3D could handle anything you could throw at it, given the right hardware.

Seems that little has changed.. 🙂

Hi Noel,

noticed your insistence in finding the point where PC might/should be brought to it's knees, why not just enjoy the sweet spot of any PC/SIM settings combination that can provide you a smooth sailing/experience instead of looking where you can fail the system and waiting for it to get stutteri?

there is no system that would be immune from getting some sort of an issue because we are in a continuance developing platform (MSFS) and new hardware with frequently updated drivers and evolving operating system (windows10/11),one of them will cause a problem (usually hidden) at some point and we will start all over again looking for a new sweet spot regardless of system spec, just enjoy the moment you have at hand my friend.
