After hours of investigating to find what maybe the cause of slight pause when flying near add on Airports i can confirm in my situation it is any 3rd party Airports that produces this bug with dx11 or dx12.
I have found with the default airports after hours of flying no problem with this bug.
Rtx 4090, FG on, TAA, Dx12, 32g Ram.
Hopefully this might help someone else may have this issue.
I replied to some topics above but it seems that it went unnoticedā¦
Iām using the freestyle filters with the 535.98 driver on my Ryzen 3700X, 2070 Super system.
Not had any problems so far.
What is a freestyle filter?
7800x3d , RTX 4090 running freestyle filters with 535.98 results in CTD
Nvidia Geforce experience has filters to adjust the color, brightness, contrast of the sim
5800x3D, 3090, 535.98, both DX11 & DX12 with filters on and no problems (other than the long-standing DX12 tile issue. I donāt believe thatās driver related)
Occasionally my world map fps drops to 11 and says there but going out to the main menu then back to the world map solves it. Not sure if thatās driver related or not.
With nVidia driver 535.98 Iāve seen the return of the purple squares, which I believe I havenāt had for more than a year (possibly December 2021, with 497.09). Is anyone else suffering the same?
@spatialpro
Dont know if u use devmode or have used it by occasion but you can
check settings in dev mode and reset them maybe that helps.
Concearning to bright image and ctd on ffreestyle filters you can mess with monitor setting saturation, gamma, brightness and colour etc settings as well on the monitor menus also its possible to set and select hz to use.
Concearning stutters i have noticed that sudden windshear when looking to the turncoordinator give large stutter also.
If these kick in at the same time with loading scenery and groundwinds than this imo could be related that graphicscard are not up to for this matter in the right way
Here is the cleaned Nvidia driver 535.98ā¦

Dev mode if off, but I had been using it not long before updating to 535.98 (it was off when I did so) 
FWIW I updated using DDU and NVCleanstall (I avoid bloatware and donāt use nVidia Inspector etc).
Hi, i use the latest driver and iām happy. i did sinse release 7 flights, all around 2 hours and no GPU crash so far. i using Zotac RTX 3060 12Gb and I7 9700K on MSI Z390 Pro with 32Gb Crusial Mem. before i used 531.29 to fly allways without CPU CTD. all drivers after this was not good for me. 535.98 works good.
Thought it was finally time to update my driver from 528.49 to this driver (535.98) and it was a mistake. I had quite the stutter fest though my RTX 4080 ran at the same numbers and temps as usual. So I reverted back to my old completely stable and ancient 528.49 driver and things are smooth as silk again.
I used DDU and NVCleanInstall as per my usual driver update procedure. So I guess Iāll keep waiting and praying that someday soon Nvidia will produce another stable high quality driver set.
MSI 4090 / DX12-ULTRA / TAA with HAGS on = lockup with music playing on main menu.
Frame Gen = off
To test, enable GPU scheduling and leave sim in welcome screen, menu animations on. Leave it playing the welcome music and put the mouse pointer on one of the menu boxes so the animation keeps looping. Wait for about 1hr and it will freeze anywhere from 10 to 40 min with music still playing or even mouse clicks are audible. Kill with end task.
With HAGS off, no problems. So this issue still persists with all current drivers.
CPU 5800x3D, MSI Tomahawk X570 Chipset, DDR4 3600. Please report back.
535.98.
Did you limit your FPS or is it going āwildā as there are no calcukations required.? Caan you reproduce it with a FPS limit set?
I thought I was being āgoodā and updated my driver to the latest Sunday. Major mistake. I had a smooth running system (I fly 100% in VR), and now it studders all over the place. Made the bigger mistake of not writing down which driver version I was running, so now I have to hunt and peck to the find the one that worked. 531.29 has similar studdering issues.
Frustrating as hell since it was running well.
Found it. 526.98 works great!

I have had nothing, but trouble after updating. I had a fairly smooth system before hand. I have rolled back and now still having very low fps, stutters and even my first CTD. I just tried the ānewestā driver and maybe a little improvement over garbage, but still nothing like I had and canāt seem to get back.

Ill have to try this. I have been trying so many different drivers to get back what I had. Iām getting so frustrated with this sim. UGH.!
