Good question--I don't have hardly any stutters anywhere since re-using NV DLSS FG set at 60 in the most demanding scenery and aircraft.  I mean just now in the Fenix 320 from EIDW to EBBR not more than one or two brief hitches presumably related to scenery load, but that was it.  In lesser scenarios, for example last eve flying the AS CRJ550 out of KTEX to KBJC, I simply hit the key to unlock the cap and this removes any kind of visual artifact associated w/ FG it's great!  I detest the strobe/flickering that can happen w/ high contrast tarmac and even ground scenery around KTEX when locked at 60FPS-fg.  Unlocked it jumped to 120FPS-fg and that obliterates these visual artifacts.  Prior to a month or so ago was able to NOT use FG but presumably Asobo did something to get rid of the 2nd screen judder I was getting many months ago prior to a new CPU when I reluctantly put up with FG related artifacts.  Most of the time up in the air FG is fine so will do the keypress or button press and re-lock the rate at 60 to keep power/heat down as it really adds nothing to run wide open at altitude where there are no significant artifacts here.

Ok. Looks like I am doing something wrong then. My monitor goes up to 180hz but I usually keep it at 100 and FPS cap (through the sim) at 50fps. I tried capping at 35, keeping the hz at 70 but still stutters. 

I need help because I am about to lose my mind over this. Keeping in mind this ran perfect in SU2

I hit a new record RAM usage yesterday 75GB … I was doing A LOT relocation to from airports in a single session along with loading up AIG + PSXT + RealTraffic.

Some of you are so long frame sensitive … 30 FPS used to be great, they 60 FPS, now the goal post is 120 FPS with preferred 240 FPS (didn’t some crazy company come out with a 330Hz monitor recently) … what’s next on the fake frame technology 😉 … and you folks hate AI? hehe

That is frustrating as heck for sure.  No idea why so different but no question IMM that frame rate has dropped big time in the past 2 months or so, so I believe for me this happened pre SU3 and persists if not worse here.   Recently landing at EBBR the native rate dropped down as low as 28 (56 w/ FG) during taxi, but lots of AI traffic so that played a role. But...no stutters even then which I attribute to Gsync for lack of a better explanation.  Once I parked at the gate we were back up to 60FPS-fg, and up to 90FPS-fg unlocked.  I use RTSS front edge sync as in my sig and it's never let me down.   I love the fact with a button press on my yoke I can toggle the frame rate lock it comes in handy in spots.  Monitor refresh rate isn't playing much of a role here--mine's set at 100 or 120 I forget.

It amuses me to think that I currently have a PC with a ten year old specification, and yet I do not use any tweaks or utilities for performance. I just set the graphics to a level that I am happy with, and go flying. No framerate limiter. No fancy AI frame generation. No dynamic settings adjuster. No shader tweaks. No managed CPU core tweaks. In fact, not even an overclock on the CPU at the moment.

Performance in MSFS 2020 (even with the forced use of DX12 mode recently) is generally excellent, with only a few isolated stutters here and there. The fact that I built this PC myself makes me so proud. It punches so far above its weight

Hello, How do you use RTSS (AMD) with an Nvidia graphics card (your signature... RTX 4090 FE...)? 🤔

RTSS is not AMD only...

That’s the new me also … just don’t have time to tweak, don’t even know what this “DLSS swapper” folks keep going on about … rBAR, tried it, no significant difference, heck I’m still 3 nVidia driver releases behind because because it works and no mention of fixing issues with MSFS 2024 (texture corruption).  I do keep my OS updated but that’s more to do with security concerns.

But when it comes to Add-Ons, oh yeah, I’m all over it … the PSXT + RealTraffic + AIG was a big win for my entertainment.

But to each his or her own, a few long frames doesn't bother me, but poor image quality does

Again, I have long term detested the artifacts associated w/ FG.  However I just got on to this and it's a very useful trick to employ.  My general approach has been to limit frames (RTSS front edge sync) but maintain around 10-15 headroom over the locked rate which since the new CPU has been 50FPS-native, no FG.  This is much less possible in any kind of demanding scenarios now hence relooking at FG and how to deal with its artifacts.  Of course when you're trying to run w/o FG at that kind of a high FPS temps and power use are up, over locking at 30FPS x2 60FPS-fg.  And I prefer to run lower power provided performance is good.  So here's what I started doing just a day or two ago:  on the ground where strobing/flicker from high contrast tarmac is really annoying (no can ignore it, especially peripherally during taxi):  I hit a button/key assigned to unlock the frame rate lock from 60FPS-fg.  Now I'm running wide open and limited by GPU/Main.  But this will shoot the rate up to as high as 120FPS or more in spots.  In the easy to process ENBR in the Fenix 320, the unlocked rate was 112FPS-fg.  This really obliterates the FG associated artifacts.  So on the ground, wide open.  Super fluid/smooth, and virtually no artifacts.  Then once in the air, hit the button/key and we're locked again at 60FPS-fg, so tons of headroom, lower temps/power, and same level of image quality and smoothness.  

Image quality is just amazing w/ the NVCP reg hack to improve sharpening, and bonus w/ the 4090 coasting along in the air supporting 60FPS-fg, I am able to set Render Scale to 130 which bumps up clarity to yet another level.  Just amazing!

Also having awful stutters with SU3. 13900KF, 4090, 64GB 5600 RAM. Before it was super smooth in any scenario, now I randomly get massive stutters. Sometimes they don’t happen at all, other times they start after 5-10 minutes. They’re actually more like temporary freezes, like 1-2 second the whole screen just freezes. Happens maybe every 20-30 seconds. Sometimes they go away on their own, other times not. No matter what test scenario I use either, and happens inflight too. Gave up yesterday flying the Fenix from KDFW to KPHL after the sim had one of those 2 second freezes in cruise and when I got out of it the aircraft was flying on its head. Started to question my hardware as it coincided with a BIOS update but all my settings were still intact. Reading about other people having similar experiences at least makes me hopefully it’s not just me.

I really hope for a hotfix ASAP - or SU4 beta.

could it be server related? how about caching a small test area and test-fly only within that region ?

Same here. The only extra I installed is Reshade. 

Some folks must have an unlimited amount of time on their hands to do all this tweaking. I dunno, or maybe they are independently wealthy and don't have jobs.😉

Well, I reset, reinstalled drivers with a clean install, used dynamic settings... hz set to 100, fps cap set to 49 and dynamic settings set to 80fps. Marked difference. 

KJFK, Batc, raas and NYv2 from samscene. TLOD at 150, OLOD 200. Preset is high except clouds are ultra. Way smoother

Sounds better.  I am stoked right now because I found a way to cope with NV DLSS FG and flying into and landing at KPHL in I-Fly MAX 8 at dusk, all Ultra, TLOD on the ground at 100, super crisp imagery and an FPS of 110 or so. The very high frame rate gets rid of most all FG-associated artifacts so it's now useable for me.  Super smooth, virtually stutter-free.  Once up in the air I will hit the lock key at 60FPS-fg where the artifacts are minimized because of being away from tarmac, so can run the sim w/ lower heat and power and have the same experience.  If artifacts start to appear I just unlock and run wide open and that is an advantage in using RTSS as you can not only toggle the frame rate lock during runtime but also change it as well during runtime.  I know many will run the sim wide open and have arguably the best possible experience w/o the need to ever alter that, but it really doesn't offer anything over judicious use of wide open and just creates a lot more CPU heat for me.  During summer now on air will see around 70-72C locked at 60FPS-fg, or wide up approaching 80C when ambient is very warm.

That is amazing. Especially since you're one of the well-knowns around here that have the fps stuff figured out. Disclaimer: I am not here, nor is Noel, an avid "fps chaser" as it doesn't really matter. Its more of smoothness. Which previously I was lacking out of nowhere after the SU3. Question though... RTSS will not let me choose msfs2024 and it keeps saying I am not authorized etc even though I am the administrator. Not a huge deal as the in-sim fps cap and dynamic settings is doing a decent job for the most part.

WIth RTSS you don't have to choose MSFS.  You just open it up, enable Front Edge Sync w/ Passive Waiting on its Settings page, and if you want to use hotkeys to toggle the lock off and on or change the lock rate you go into HotKeyHandler.dll and set it up there.  The high frame rate definitely is desirable but truly it's mainly for its ability to brute force mask the artifact issue. 

Here's what RTSS should look like.  Note we're not using Scanline sync, just Framerate Limit.  

Click Setup, and scroll to Compatibility Properties:

Cool bonus:  you can toggle the limiter on and off while flying w/o stopping by using RTSS' HotkeyHandler.dll.  You can see I use Num * button on to toggle the limiter off and on.  This is useful to see where you would be unlocked.  And if I'm at an ultra demanding airport where the unlocked rate is essentially to my lock at 33/34 I'll run unlocked until up and away, then a simple button press returns me to limited (with its superior FTV and lower demand on hardware).  NOTE:  if you can't get this working mssg me

I hope this helps others it's been an absolutely astonishing finding and has made all flights a joy.  I tried all other methods to get here and none match this.  I'll not be upgrading my hardware anytime soon!
