    Noticed this in "Test Day" mode as well as "Race". If the track has a 2x multiplier for time, i'm getting a random stutter every ~20-30 seconds. Tried multiple cars and tracks, but it continues to happen unless I turn off the time multiplier.

    12700k/3090Ti with latest NVIDIA drivers
    Tried in Windowed and Full screen mode
    Triple 27" screens
    I turned off the UDP as well (no effect)

    Well, it's more than time acceleration. I'm still getting stuttering with the latest release even with time acceleration disabled. It's consistent across multiple cars and tracks.

    What i've tried:
    -clean install of AMS2
    -four different driver versions from NVIDIA (on latest now)
    -disable UDP
    -disable time acceleration
    -turned all graphics to low (still present)

    I don't know what else to look for at this point. Something has changed and it's causing a ton of stutters. No other game has this issue.

    Can you record a video of it?

    Below is a recording (sorry it's in triple screen format). I've switched to single screen and the problem persists. Driver 512.96 from NVIDIA which is the latest (I've tried four different ones). I've cleaned out my docs folder including triplescreen and ffbcustom settings files. I don't see this in any other game, so i'm just puzzled as to what is causing this.

    Very strange indeed. Have you overclocked something as well?
    @CrimsonEminence Are you aware of this? or anything similar?

    No overclocking for the GPU. The CPU has the standard ASUS overclock but this issue is relatively new. I'd say it started about a month ago. I don't remember having this issue previously in either the beta or the main build.

    Well, will see what Crimson says about it. Hope he replies.

    I have started getting stuttering again, noticed it quite badly at Monza 91 and it was the old bug where there is significant stutter when the AI pits. I thought this was addressed previously?
    I also have just noticed an fps issue where the game is only reaching 125-130 fps when capped at 143. The GPU is only running between 40-50% and the CPU single core up to about 70%

    New NVIDIA driver released yesterday. Installed and unfortunately no change.

    To troubleshoot this, I would run the game in a window with the Task Manager running alongside, looking for any process taking CPU usage when the stutter happens.
    Using MSI Afterburner/RTSS to display the frametime graph might also help to visualize the stutters.
    Other than that disable every game overlay (Steam, Xbox, NVIDIA's...) or programs hooking other apps (OBS, ...). Also disable any USB device not strictly necessary. You could even check if you have this issue disconnecting your wheel and using the keyboard.

    Looking at CPU, GPU and SSD usage. CPU is in the ~30% range, GPU is around 92-100%, however what's interesting is that the SSD is spiking every so many seconds to 100% and when it does there's a stutter.

    I loaded up Nurburgring GP on a test day and it's constantly hitting the SSD for some reason. I would assume the track would be loaded and then done. If I do this test with ACC for example, the SSD is active during the loading phase but is not active during actual driving on the track.

    I think there's a process within AMS2 that is polling the SSD for some reason.

    Maybe your son or daughter or so went on your computer and spend some time browsing things they shouldn't be browsing and now your computer has joined a crypto-botnetwork?

    I am getting very bad stutters in race mode and reckon it is related to have pit crew visible when the AI pits, this was a bug a while back but I thought it had been fixed as not had issues with it for a long time. It has only come back since the update

    Maybe it only executes it when you play AMS 2 so it doesn't look to shady... :p:oops: but eh.. I don't know. its strange, tho.
