    @netqvist I78700K, RTX 2080 Super, 16GB ram, Nvme SSD - stable fps 55-75 after a few hours of play (Ultra 2560x1440)

    The game stutters constantly, even in menus. It's enough to give you motion sickness. Every so often it runs smooth but it's like this 95% of the time. I've tried every single fix I've seen elsewhere:

    • I have the latest drivers.
    • I disabled full screen optimization and I've tried borderless.
    • I get the same thing on low or ultra high settings.
    • I've turned all the Radeon settings off and all on. Same result.

    My freezes and stutters stopped when I disabled hybrid in the control settings.

    Same problem here... 9900K, 3090 RTX, 64GB RAM, 120Hz 4K HDR Gsync display (mostly ultra getting ~80fps)

    I'm not CPU bound nor GPU bound. As a game developer programmer, I suspect the following:

    • Tends to trigger in high populated areas, especially during raids with monks running around. Likely hitching on pathfinding or ai states. If you run away from the monastery, it clears up, only for it to get worse again when you return.
    • ...but you would think moving on to a new area would clear it up, but it doesn't. It persists. So failed pathfinding moves feels less likely.
    • Seems to also trigger during cutscenes as well or get worse.
    • When running through the world, it's less of an issue. Once you get near people, boom...
    • Once triggered, it's permanent and over time gets worse (except while solo exploring open areas).


    My guess without knowing the tech -- maybe there is some sort of memory pool recycling/reset issue with AI states or pathfinding, or potentially a thread contention issue. I'm going to watch my cores to see if any of my cores are maxing out/spiking...but I rarely see over 50% utilization (8 cores - 16 logical cores). This almost certainly has nothing to do with performance settings. But once it triggers, it only gets worse, and restarting the game fixes it... for 30-60+ minutes (longer if exploring, sooner if raiding/major battles).

    Loving the game so far, wish I didn't have to keep restarting the game to lose the hitches.

    @cazora Yeah they need to fix this ASAP, restarting game every hour getting old😧

    @strunkero To no avail, its not helping. I have had some luck closing the game completely and restarting once the stuttering gets to an annoying point. Once it starts, the longer I play the worse it gets.

    More observations:

    • Possibly triggered by civilian panic states during raids or large battles in populated areas.
    • Causes some kind of corruption involving NPCs
    • The spikes happen in areas with more people, actively drawing them.
    • When you walk away from people, the spikes nearly go away
    • Gets worse over time. The F1 graph shows massive spikes (I'll get 70fps average, but the spikes have a high amplitude both ways (down to say 20 and up to my cap of 120).


    So possible garbage collection issue or processing invalid data (anims, models?)

    @cazora Ye I've noticed it seems to be related to populated areas. One of the worst offenders is really long monastery battles which would kind of fit with the panicing NPCs. It just goes into a slideshow if you keep dying in them. I literally have to restart before doing a raid just to be able to play them through if it's a larger raid.

    @netqvist Yeah during the monastery battles will kinda trigger it. Sometimes during cutscenes will happen too. Is there any devs looking into this issue at all?

    Yeah, happens exactly the same to me. But I've noticed that if I've had the computer running for a long period of time, I'll start the game already stuttering, and if I restart the PC I can start the game buttery smooth, but like half hour after the stuttering starts and it only gets worse and worse, not even a restart of the game fixes it for me at that point. There also seems to be a server-side issue cause the game borks everytime I take a photo using photo mode. The game literally freezes for a few seconds when coming out of it. This is really frustrating... Ubisoft really needs to invest in their QA team/process cause this is unacceptable for a game they charge up to 130€. These kind of issues shouldn't happen. I love Assassin's Creed, but this is getting really annoying by now.

    Ryzen 7 3700x & RTX 2060 here. Also having the stuttering issues. Seems like when there are multiple NPC's around, the frate will fall down into the 20's & 30's. Tried turning off "full screen Optimization" and turning off windows game bar, ( as recommended on other forums) and played with the graphics settings, but cant seem t find a fix. The odd thing is that it will run super smooth at times even with multiple NPC's on screen and then all of a sudden start stuttering badly for a bit, then go back to running great. Any help or insight from UBISOFT would be most appreciated!

    I found a video on YouTube



    I agree with your suspicions that it is a suspected memory leak. I was able to mitigate, but not eliminate the stutters by increasing the page file size in Windows.

    I have a Ryzen 7 3700X, 16 GB of DDR4-3600 RAM and a Sapphire Radeon 5700XT. I run the game at 1440p using the the Hardware Unboxed Optimized settings and I get 60+ FPS.

    Let me know what you guys think?

    Cheers!

    Have you tried whacking the volumetric cloud setting down to the lowest? I've found it's the biggest culprit of things going wrong in mine. Since I did that I haven't had a deterioration problem for a couple of sessions (fingers crossed). This is in combination with forcing the full screen optimisations off that someone alluded to earlier in the thread.

    @falo2k I'll give that a shot. I remember the Volumetric Clouds setting having a huge performance impact in Odyssey.

    @tyranusvader Fingers crossed. They're definitely linked to some other issues such as clouds going weirdly blocky on the latest nvidia drivers.

    @falo2k The stuttering occurs whether one has an AMD GPU or Nvidia GPU. Not sure an updated driver will rectify the issue. I got a feeling that it's a problem with the game code. From what I'm reading in this forum, Ubisoft engineers are aware of this issue and are looking into it. I hope that this issue is put on the top of their list of things to fix.
