I do not.
In fact, now that I think about it, I dind’t even have my PC’s power plan set to Best Performance; I left it on Balanced. And I had Chrome open with 8 - 9 tabs, along with Outlook, Discord, and even Steam. I’m sure those were all sucking up some CPU cycles, but I simply let Windows (Win11) do whatever it wanted with its internal scheduler while I futzed around with the sim. In my edits above, I was actually letting the sim run in the background while I was surfing with Chrome, watching VRAM go up and down as traffic moved around in drone cam.
But the tl;dr here for me is, I do not use anything to try to force Windows to use certain cores. But to that point, my Intel CPU doesn’t even have e-cores, let alone AMD’s X3D tech.
I also do not use process lasso for forcing cores. I use it to trim memory off other programs and limit not being on the central core.
I did do another clean reinstall of the Nvidia Driver. I’m going to test again to see the results.
Additionally, as I sit here and think, I remember completing some flights between KCLT, MDPC, and Back. The VRAM maintained itself quite well. I am not wondering if it is, in fact, a handcrafted airport issue that was not correctly optimized.
That’s why I’ve mostly been sticking to GA aircraft as well and avoiding large airports. 2024 is absolutely amazing for GA flying. 2024 does seem to run better than 2020 as long as you avoid large airports, and some of the default airliners are pretty FPS heavy, especially the inibuilds ones.

I think I’m close to figuring it out. The major problem is the scenery is way too demanding. Further optimizations of scenery is required. Also more better LOD culling is needed and obviously better VRAM management.

For what it worth with my 3070 I have realized I need to just dial back my settings. I ran the same scenarios in MS2020 and they run about 10-20% faster, but can’t really go back.
To get consistent testing I am running the ILS approach on autopilot into SFO on 28R with both the B-787 and the C-172 and pausing for VRAM and FPS readings every 500’ down to the runway from 2500’.
In sum, what I found was that the 172 used between 4.5 and 5.5 GB of my 8 and ran at 40 in TAA versus 60 in DLSS.
The 787 used between 5.5 and 6.5 GB of my 8 and ran at 25 in TAA versus 55 in DLSS.
Conclusion, I am pretty much going to have to run in DLSS and stop complaining. I do worry about those who are having problems with the higher end cards and I see they have to dial them back also.
Anyway, good luck with those high end cards and I believe I will get one next year but not for Xmas…
I’m starting another flight. This time, I’m testing two theories.
- The airport is the problem
- The clean install (safe mode) of the Nvidia Drivers.
At gate KFLL (Third Party) VRAM 10~11GB
Climbing out over Boca Raton, FL 9~10GB
Descending into KATL 7~9 GB
At the ground at KATL - 10-11.5GB (Similar to what I had experienced at KFLL.
These results are promising. I will test a KATL - KJFK trip tomorrow and see what the result is at KJFK.

So after a clean up with DDU and a reinstall fresh with the latest Nvidia Driver I seem to have the VRam bug in check now, I set memory management to ‘prefer no sysmem fallback’ and set anisotropic filtering to 16x in the NVdia control panel.
I am now within Vram budget of max 12GB (sitting around 10gb usage) consistantly, and FPS are rocking now with rebar enabled and frame gen mod on a RTX3060. Incidently shared memory doesn’t go above 1gb now.
This is on High Preset.
Thanks so much for sharing! 
That works for me for now.

Ryzen 7950X3D, 3090 Ti 24GB (566.14), 2x32GB DDR5-6400/CL32, 1Gb Fiber, WiFi 6
DLSS Quality, mix of Ultra/High/Medium, TLOD=150 OLOD=150, Live Traffic, Live Weather.
- Rbar and >4GB enabled (enabled by default in my Gigabyte BIOS.)
- Ultimate Power Plan
- Windows Game Mode = OFF
- Xbox Game Bar = OFF
- HPET (High Precision Event Timer) = DISABLED
- ISLC (Intelligent List Standby Cleaner) = ADDED and ENABLED
- Process Lasso controller affinities and priorities. This was a very interesting PL setup video by Savitarax. I followed his instructions carefully, and the sim is running VERY smoothly for me.
I was quite amazed that setting almost all the Windows process priorities to ‘Idle’ seemed to be a good idea.
(NOTE: He points out to be careful not to touch many specific Windows System processes.)
I did some testing (results in this thread) and found that core affinities (i.e Vcore only, non-Vcore only, or all-core) didn’t seem to affect performance.
I make no claims regarding the effectiveness of any of my settings, or addons.
I can only report on the performance of the sim on my system, and the configuration of my system.

would you be so kind as to report back loading the ini a320v2 on the runway at jfk, traffic on

Folks, why are you all missing the point?
This screenshot says all you need to know about this bug …
Summary: Once garbage fills up the shared GPU memory (ie. taking a big airliner at a busy airport), I can subsequently swap the airliner for a microlight and go to a deserted airport and the main VRAM drops, BUT the junk in shared GPU memory simply stays there.
I don’t understand why people are going around in circles with all kinds of suppositions, when it’s staring at you in the face.

That screenshot doesn’t show what you seem to think it shows. Your shared GPU memory is nowhere close to full, nor is your dedicated VRAM full either.
However, the bug, to the extent it exists among those who are experiencing it, seems to be when the sim (and/or Windows itself, in conjunction with the GPU driver) is failing to purge items from either VRAM or shared GPU memory.
The actual question to ask is thus what is it about those experiencing the bug that is causing the sim, Windows or their GPU drivers from flushing and purging data from VRAM and any shared GPU memory when required.

I tried that and it makes no difference at all. Shared memory still shows in Task Manager.
And here are two screenshots: Both at the Start page. The first one is as I’m about to quit to desktop. It shows 3.2GB in shared GPU memory.
The second screenshot is after I return – ie after I’ve rebooted back into the sim.
It shows that the shared GPU has been flushed…
I decided to sell my RTX 3070 8GB, because I got 10 FPS at big airports on HIGH settings 1440P
I bought a RX 7800 RT 16GB and now get 50-60 FPS at big airports on ULTRA settings 1440P
My guess is that their information about the system requirements were all wrong, because Third Party scenery is much more VRAM dependent!

Well, with DX11 it got flushed, since the driver takes care of that.
But with DX12, I understand that the coder of the game / sim is responsible for the GPU’s memory management.
Edit: My guess also is that for FS2024 the coders have not set a ‘sliding’ purge threshold ie. to work with a wide range of GPUs with different VRAM capacities. Rather, I suspect they developed and tested the sim using their own high-end GPU hardware and set their VRAM purge thresholds accordingly, ie based on, say, a 24GB VRAM capacity. This would be why cards with less capacity just fill up to max, and then spill over into shared memory, which is then not cleaned-up.

I took off in the middle of nowhere in the midwest of US - Asobo basic otter
Just some clouds from sim presets
I was getting 60 fps consistently - I said hmm ok Ill get out of sim restart and do same exact scenario - I was getting 24fps
Asus 4080 super oc - 64 gig ram - high end intel cpu - 1gb internet
Moral of the story to me is the streaming is inconsistent and I dont find waiting for 3 to 4 mins for sim to get to free flight acceptable
I noticed my GPU was running at 99% and my CPU running at 26% something is not right, I’ll wait it out - hopefully they can work all of this out
One more thing real weathers pretty good but killed my fps also
Streaming is the big culprit and all these tweaks isint going to help that much until Asobo addresses base sim in conjunction issues with streaming issue - its both that need attention imo

Thanks man, I’m for sure gonna try this! I have a 3070Ti 32GB of Ram and a 7800x3D. I only play at 1080p and High settings so I should not be getting 7fps haha!

I have a 3070… please don’t tell me to sell after fooling with all the settings for two weeks… PS I am getting much faster FPS,
Also at the handcrafted airports by Gaya?
For me NVIDIA RTX failed, because of the too low 8GB VRAM

It was slightly better for a few days, but today it seems worse again somehow. My VRAM usage was about 11 GB at big airports/cities with texture res set to Medium. That is still a lot as there are a lot of cards that don’t even have 8 or 12GB, but hey i have 16GB.
Now suddenly i am at Quito and the VRAM is full again. Quito is not a very large airport and it’s mostly trees around. Setting TLOD and trees lower did nothing though. The usage at KLAX for instance is now also high again while a couple of days i had it under control.
