    For those of you on a Nvidia 30 series card I found a solution that worked for me. I originally had a +125 core +250 memory OC (very stable and works on all other games I play) on my evga 3090 ftw3 and that would cause the game to crash constantly. I tried all the different methods posted and was not able to get the game not to crash. The game would also crash on the default settings on my card. What fixed it for me was undervolting my gpu. My card will not boost past 1950mhz because of the undervolt and I have gone crash free for 3 days now and this is with all graphic settings maxed out. Before my card would boost to 2010mhz (stock settings) and 2100mhz (my OC profiles) And game would constantly crash. Hope this helps some of you.

    @edengonzalez86 I have a 3070 oc tbm, in case you downloaded -125 core - 250 memory it?

    @edengonzalez86 This works for Pascal too except you need to downclock quite a bit which results in a big performance loss.

    I just tested again with a +100 core +250 memory and power slider at 100% instead of 107% and I'm able to play the game with no crashes. Seems this game is very sensitive to clock speeds. Was able to play with a steady 2000mhz on the core. I didn't get to play as much as I wanted. I'll get to play for a few hours tomorrow and report back if the game crashes or not.

    I have the same problem. I have tried everything that was written here and it still did not fixed it.

    And they don't want to pay my money back. Ubisoft support chat.

    I recommend everyone to raise dispute with your credit card company to claim back your money because ubisoft will keep on selling not working product for more people until they realize that they have to fixit otherwise they not gonna get payed.

    @edengonzalez86 I can confirm that putting the slider on 100% instead of 107% fixed the crashes for me (at least for now, played for few hours so can't quickly judge)

    I had crashes every ~30 mins with the power slider on 107% with stock mem and core clocks with my 3090 ASUS TUF.
    Thanks dude. Hopefully it stays that way and the crashes are gone 🙂

    This is the only game that gets my core clock speeds close to 2000mhz with stock clocks while all other games barely hit 1900mhz. Not sure if it's a driver or game issue, what I know is that it's hard to imagine that ubi is innocent so it's either both or only ubi's fault.

    @eniora let me get it right, do you increase the use of energy to 107% of this? I'm a layman in this aspect of over

    @bendelaboombr Originally I had my RTX 3090 set to 107% power limit in MSI afterburner (with default stock core and memory clocks). This 107% power limit used to push my core clock in Valhalla close to 2000mhz which resulted in display driver crashing. Now with it set to the default value (which is factory 100%) the GPU averages 1920-1950mhz and I have no crashes so far.

    @eniora yes I understand, mine is already in 100% standard, gainward software

    Just came here to say that Canterbury is literally crashing here too on my Intel/Nvidia System similar to your current experience. And as others too it will always afterwards show up in the Windows Report too that the Game is crashing the most recent Nvidia Driver.


    This can be repeated as much and as many times i want to do it. The installed Nvidia Driver is the 460.89. Whatever the Game is doing, it does crash the Nvidia Driver in Canterbury and probably other Regions too.

    Legion too crashes like the same way for me. The common denominator here: Ubisoft Connect. Reducing/restricting the core clock does fix it and disabling connect overlay as well.

    @redindianrobin it looks like a stability with the factory OC cards. This can
     be fixed with drivers or by ubisoft?
    debug mode from nvidia seems to work for me, i managed to play a few hours without problems, i will do more tests

    I found a solution that works for me, so hopefully it can help some of you. I’m on PC Win10. I have the same issue where the game can randomly freeze but the sound continues, anywhere from 5-30 minutes of gameplay then CTD.

    After I start the game, I immediately alt-tab then bring up the task manager. Click on details tab then right click on AC Valhalla process. Change the priority to high. I haven’t had a crash since. This has to be done everytime you start the game as the priority always defaults to normal.

    @bendelaboombr What's this debug mode you're talking about? I'd like to try too.

    Also yea with a year old drivers, for example the 44x.xx, it doesn't crash even with OC and connect overlay enabled. I don't know who's the culprit here, Ubisoft or Nvidia but other games have 0 crashes. Currently I am playing Cyberpunk and Red Dead Online and neither of them crashes with OC.

    Cyberpunk 2077 does not CTD on me. This game does....

    Ubisoft is definitely the culprit here ...... It's up to Ubisoft to make their product work with the Nvidia and Microsoft APIs not the other way around ......

    You might as well give it up because this isn't going to be fixed until the next scheduled content update in 4 more weeks ...... And if it doesn't get fixed in 4 weeks you'll have to wait another 6 weeks ...... That's just the way the AC series has been run since October 2018 when they went to the live service model .... They will not go off their 6 week schedule as long as people continue to play the game ...... The ONLY solution to get them to modify their behavior is stop playing the game so their server logs show a massive drop in player engagement .......

    I guess they have never heard of hotfixes?

    Typical lol. Even Indie developers roll out better support for very prominent issues like this.

    Same is happening to me in Valhalla, the game crashes every 5-10 minutes, unplayable at the moment
    i've tried everything, update driver/windows 10/extension of virtual memory/enabled high priority process with task manager/downgraded the graphics/enabled hardware gpu acceleration...nothing seems to work
    I've tried also old drivers, but nothing works

    the game seems amazing but with these problems it's unplayable
    idk if the problem is the game/drivers/ubi connect..

    @fantazyz78 Thank you, it worked! You saved me a lot of time! Jesus! 😄 Syncronizing my windows clock, that was the solution.
