How to restore the sim to its vanilla state – Microsoft Flight Simulator Support (zendesk.com)
I think this thing will stutter I intermittently even if you use a 10080ti overclocked

Thanks for the explanation and yes it makes sense to let the gpu use it’s resources on other things. I’m guessing low end or older cards should set it on or even off entirely.
Mine’s quick enough for ultra so that’s where I’ll set it and I’ll keep an eye on it.
I am running an i7 10700k and RTX2060super on 1440p ultrawide and there are times I can become CPU limited bringing in stutters and fps drops. Even if I lower my rendering scale the fps would significantly increase but the stutters were still present. Happens mainly at big airports.
Majority of the time I mainly GPU limited making the sim run very fluid.
All my Nvidia settings are set to default.
My settings are a mix of Ultra and High
Yes that’s a very good link but I will suggest for those that have marketplace mods it’s always best to look in known issues first as there could be no need to uninstall all of them, just those mentioned. No guarantee of course because Asobo rely heavily on devs actually reporting their issues.
Don´t get too obsessed with FPS as this is not a first person shooter where you need to achieve 120fps to have fluid movements and precission. In this type of heavy simulator it´s better to get stability instead. While flying you will notice much more a sudden 10fps drop than an overall average low fps rendering that is maintained over time.
In my opinion in MSFS is better to get rid of microfreezes and stuttering instead, even if that means to play at lower FPS. At the end of the day for that you will need to sacrifice some of the visuals, either the draw distances, AI traffic, render qualities, etc. So set the things according to your system capabilities and just forget. Also every airport and area behave differently, as in some cities there are several airports in short distance and also tons of buildings while in others there´s just jungle or desert around, so it´s impossible to set a magic combo that works well in all cases.
The safest approach is to leave some room for your system to work up to its optimal performance using some of the worse cases you faced as a reference test and tune settings there with an affordable situation for your system (not at Denver with 300 parked planes, 50 more landing at once and heavy rain for instance). If sim works well there it will most likely work well in the majority of the airports too.

I’m not worried about the FPS. I’m worried about the constant stuttering when on approach. I am mainthread limited as per the dev mode fps counter. So is anyone willing to help me figure out which settings to change? I currently run it at 1440p as my monitor allows it.

Just start by disabling the HW accelerated GPU scheduling, as I explained. This is the main source for stuttering and it creates stuttering everywhere, even at the sea. You can skip the NVIDIA low latency mode proposal as this may reduce your overall fps. Then for the game settings what I have is the following, and this works very well on my case:
All settings maxed, except:
- Clouds to high
- Terrain detail to 200%
- Terrain shadows to 1024 (in case your fps drop a lot with cloudy weather when using 2048)
- Parked aircraft to 0 and AI aircraft to 20% (I use Aerosoft Simple Traffic)
- Optionally: glass cockpit to medium → this makes the onboard screens render at lower refresh rate and there´s just a minor difference in quality compared with high but a huge improvement in performance
Just that is enough. The main fps killers are clouds as they affect a lot of other things related with light, like shadows or reflections when they are between sun and you. The second killer is the terrain viewdistance as it defines the amount of high details seen at a distance and the last is the amount of AI planes. Rest of things should be handable by your system and they don´t really kill performance that much, unless you try to run 4k with 200% rendering scaling, which is not your case.

Weird I already had it set like that except for the clouds. I had the clouds on ultra but everything else was setup how yours were and I was still being cpu limited.
Hopefully DX12 will get optimized soon!
Read the full thread it’s explained.
Reduce LOD from 200 to 175 same for Terrain keep everything at full Ultra and most importantly increase render scale to 185.
This will force a GPU limitation keeping LOD at 200 ain’t gonna take the load off the CPU.

Remember the most important setting, and the mother of all stuttering (at least as of today). Disable GPU scheduling in Windows:

I find it interesting to see that HAGS seems to be such an issue on higher end systems. It is literally one of the difference makers on my non CPU bound laptop with mid/low end GPU from a stuttering/panning perspective. There are clearly benefits to some systems with this windows setting and I have it turned ON all the time. Makes a huge (few fps) difference on takeoff and smooth panning in cockpit whilst taking off, and that is with my GPU at 100%. I guess it’s highly system dependant.
Is there a plan for the development to try and use more CPU cores? I mean, to be main thread limited at 10-20% seems somewhat counterintuitive. Really, folks are stuffing 16 cores on the die, seems like the programmers could at least use 2, or even 4 of them.

Pretty sure that’s the plan but as we saw with SU5 it can cause coding and particularly syncing problems. However I would imagine much of the newer code incorporates the necessary hooks already. Only time will tell.
If I put my render scaling at 185 will that take it out of 1440p?
Doesn’t work exactly like that. It looks to be a pre-display resolution that the sim renders the scene at, and then your final display will be whatever you have the “full screen” resolution option set to.
I followed those settings and no difference so I’m not sure what the issue is for me. I’m thinking maybe a fresh install of the sim might be in order.
I also set my settings to medium and applied them just to see and there was literally no difference in how anything looked. I was at KLAX and went from ultra and looked around then switched to medium and looked around and everything from buildings to cars to terminal looked the exact same…
No don’t do it yet wait for the hotfix and see!
