    Bro!! Thank you!!! I was just looking this morning for a driver update as I was having performance issues that seemed random. Again, you and I are kindred spirits. lol

    I too had severe stuttering in Norway at Oslo yesterday. I just upgraded to this driver and will hope for the best.
    I also decided to check and make sure my DLSS was up to date and surprisingly I saw MSFS 2020 is now recognized as a DLSS swapping game. I have not used 2020 since 2024 came out.
    I don't know if this driver recognized it our MSFS since I have not updated MSFS 2020 for quite a while now.
    But thank you for all your comments, they have been truly helpful.
    May you and your family be very Blessed in this coming New Year.

    I have just upgraded to 566.45, havent tried it yet but I noticed the option in the custom install for a clean install and wondered if that did a cache clear at the same time. It would seem logical and would simplify the upgrade a lot. Thanks for the video mate.

    This worked wonderfully for my setup. Installed the hotfix, rebooted, cleared cache.
    Flew from TFFJ to TNCS in the Islander (2020) and the Black Square Analog Caravan (2024).
    Buttery smooth with maybe a couple of stutters (but couldn't quite tell, but might have been because of rebuilding the shader cache as you noted).
    I got 120 FPS on 2020 and 80 FPS in 2024.
    For 2020 I have DLSS/Performance, Scaling 2, DLSS 3.8.10.0, Frame Gen, Using AutoFPS.
    For 2024 I have DLSS/Performance, Scaling 2, DLSS 3.8.10.0, Frame Gen, Using Auto FPS, Raytraced Shadows, 50 GB Rolling Cache on a 60GB SSD .
    The specs for my PC are:
    GPU: GeForce RTX 3070 Ti
    CPU: AMD Ryzen 7 5800X3D 8-Cores 3.60 GHz
    32.0 GB RAM
    2 Monitors (2K 180Hz and 1080P 60Hz)
    Windows 10 Pro
    I'm sticking with this setup too. I don't want to change anything on either Sims configs now that they are awesome! Can't wait for Blackbox to release the updated Islander version for 2024.
    Many, many thanks for all your excellent videos, especially this one! I always look forward to your next video.

    I've been having that large periodic stutter while in ground operation. I refer to it as "being caught up on something and then snaps loose". All's good once airborne. Figured it was my TLOD / OLOD settings but after messing with those with no improvement, I decided to just leave it. I'll give this a shot. Thanks for the video!

    It's odd to me that Nvidia hardly mentions MSFS when drivers are released, or for that matter adding specific MSFS improvements, given it's popularity. Might be due to agreements or partnerships with game makers that they target certain games and not others, not sure?? Anyway, great video as always. Thank you for your great content over the year.

    I can confirm the same as what you saw . Went to .45HF1 from .36 yesterday and the micro stutters also went away. Also noticed some non response at Windows start up too on .36 for a few seconds. Its odd that fault is seen in some drivers, but not in every one. It was the reason I stayed on 537.58 for nearly a year in FS2020. I have a 4090 with a 7950X running 3 x 4k in a sim pit.

    You might want to check if those planes are optimized for FS 2024. I had a similar issue with the Black Square King Air, although it was less noticeable with native, out-of-the-box planes. That said, I still need to verify how things perform with this new driver, as I’ve uninstalled it for now.

    Trim drifts around a poorly designed "center"and NEVER settles. While drifting onward past its set value it eventually requires an opposite
    trim move which also wanders past its set point in the OPPOSITE direction. I seem to be always chasing it up and down.

    I do not know if it is my continuous endeavour to tweak MSFS 2020 or the W11 24H2 or the last updates from Asobo or the new NVidia driver or a combination of all of this but I noticed in the Task Manager that there is no longer a thread busy at 100% and the sim has never been so smooth and crispy !
    By the way I stopped using Process Lasso but continue with Map Enhancement and FSLTL mods and set the SecondaryScaling to 1.25 with DLSS Super Resolution to Balanced.

      The VRAM usage is a bug in 24 at the moment as well. However disable RT shadows and AI aircraft, turn down the texture setting by a single level as well. There is zero reason (other than the VRAM bug) that 24 performs less well than 20 as it's far better optimised for multi core CPUs!

      @@Patrik.Pereira That makes no sense at all. Do you have a lot of background stuff running? LODs at 10 and still having issues is indicative of something pretty major going on. I assume fast, stable internet connection? Have you tried a VPN?

      Not only. From Nvidia:

    What you should be telling everyone especially those with higher end cpu’s and gpu’s is to undervolt their i9’s and 4090’s. My stuttering was all caused by thermal throttling of my i913900k due to temps getting pushed especially on approach into busy airports. The Sim really pushes the hardware all the way to its limits in certain scenarios even the 4090. Once your temps spike, and the processor gets throttled you get massive stutters and in some cases system instability. Undervolting gives you that headroom back and allows your processor and gpu to boost properly when its getting hammered. no more stuters for me so why not try it?
