Some users are experiencing crashes here is how to fix it.

[Nuriyokan]

So you have two categories AMD and NVIDIA. What can cause crashes are issues with a recent , or outdated driver . Make sure your drivers are up to date . The game isn't broken and works but even people on new systems still get crashes .

0.) update your drivers , bios , and OS.
1.) verify the integrity of the games files via right clicking the properties on said game.

now... some people said you can't run the game in DX12 and the fix is to run it in Dx11 by adding -dx11 into the properties . This CAN work but this is WRONG . You CAN run the game in dx12 with zero crashes .

Most often than not especially if you are having this issue with a high end PC... is that your windows installation is broken . Open cmd and type sfc /scannow hit enter ... this will let you know if you have broken installation files . If so run the command below.

Open cmd as administrator and type DISM.exe /Online /Cleanup-Image /Restorehealth hit enter and this will fix your installation if its broken.

Restart your PC , now reinstall microsofts VC redist x86 and VC redist 64 redistributable files . Each one needs a restart of your PC but i just installed them both then restarted . You are supposed to install x86 restart , then x64 restart again .

I am an AMD user and this took my game from crashing every 15 minutes to all day of play with no crashes .


//

IF NONE OF THE ABOVE WORKS THEN THIS ONE WILL .
Say that windows for some odd reason can't repair your broken installation .
1.) Make sure your entire PC has no malware , trojans , etc
2.) now move all of your game files over to a new drive . So copy your entire steam folder over to a new drive . once you do this and have backed up all of your C drives files , You are going to reinstall windows to the C drive. After reinstall you'll need to reinstall the VC x86, and VCx64 .

RESTART

3.) Download steam , log in and take your backed up steam folder and overwrite it in the program files x86 ,steam path on your C drive. Go to your library via steam and install the game. What will happen is it will read your games off of your drive instead of re downloading them .

All of this should only take you 20 minutes . oh game fully runs at full screen DX12 at ultra settings so don't listen the misinformation about having to run in in dx11 at medium settings , or turning off ray tracing ... that statement is false.

I have 23.5.1 drivers (used DDU before installing them), don't want to update to newer ones released a day ago, pretty sure they won't help here. I've updated my BIOS few months ago for the sake of RAM compatibility, don't want to update BIOS again, cause everything works fine (or so it seems). My Win 10 is up to date I believe (21H2, 19044.2965). Verified the game integrity a week ago, after uninstalling few mods, just in case. The game reinstalled DirectX and VCRedist at that point. I had an issue with one software not related to games, so I did sfc /scannow and DISM.exe /Online /Cleanup-Image /Restorehealth few days ago. Everything was fine, just a couple of missing bmp files I've deleted by mistake and few files unrelated to gaming or OS stability.

But before starting the game I've reinstalled/fixed 2012, 2013 and the latest Visual C++ Redistributable packages from this page[learn.microsoft.com], just in case. Both x86 and x64.

Well, low and behold, the game still randomly crashes when DX12 is enabled.

But, man, the sheer audacity of your post is quite striking. If such trivial things you recommended really helped make DX12 stable in this game, the issue wouldn't be so spread out to begin with. That's not to mention a very specific drones related bug Nvidia users had (still have?) recently.

Switching back to DX11...

The sheer audacity of my post ? I think you should not let your emotions get the better of you to the point you insult others. The sheer audacity of my post ? This is what worked for me . I stated that i had AMD and i mentioned that you may have NVIDIA. Not all Nvidia users have crashing issues with this game. Some have gotten it to work even in Dx12. You told me you installed x86, and x64 a week ago. You also said that you updated your bios in the past but didn't want to do it again. well their are things you weren't even willing to try. Windows forces updates even the small one that you don't really see visually . Many things can conflict and cause issues .

You actually could get the game to run in dx12 without issues if you followed my post AND did what was neccessary for Nvidia's side. Don't talk about " The sheer audacity " of my post as if what i said was nonsense because this has worked for people . Most often than not ( learning this from a computer technician that has over 20 years of experience and has worked with windows since windows very first build ) its the OS in the end.

The very same guy who taught me this told me how stubborn people can be , how they don't follow all the steps because " i did that already " " i don't feel like " then these same individuals say something doesn't work which is false . People on youtube have videos running this game on Nvidia in dx12 with no crashes as well as AMD . Why is that ? Because they fixed their OS. The game has been patched and I'm telling you I'm no longer getting crashes on the side of AMD. Someone just a few days ago who is also an AMD user told me the game can't run in Dx12 without crashes and you can't run it at ultra settings . He was so wrong .

The guy who taught me about fixing my OS showed me how to do this with any game. I have a modern PC and can run anything at max settings with no issues . Yet some games AFTER PATCHES would not work without crashing . After running test and finding out that my hardware was not the issue i contacted a man who had this information . I learned something new instead of having an ego . I fixed the problem and a few friends of mine fixed their problems as well ( nvidia users by the way ).

Its not the sheer audacity of my post but rather the sheer unwillingness to see if you might be incorrect .

[Nuriyokan]

oh and those people on YouTube have the game running ( Nvidia ) in 4k , with ray-tracing on in dx12 ... their game doesn't crash but for many average users it does . Why is this . If the game was broken it would work for no one at all not just a few users . You live and you learn ... some take longer than others . Many feel that they are above learning something new and this is what hinders people greatly . Have a nice day.

Insult? Where? I talked about your post, not about you.

Legion isn't stable in DX12 mode for lots of people. My friends online have random DX12 crashes. Today a guy I played online with crashed, because of DX12. People (myself included) tried to find a solution for months, nothing helped.

And then you're saying that people are WRONG using caps, and instead of describing your rig and providing an obscure solution that might finally fix the game mentioning typical steps Ubisoft support recommend everyone to do when they contact them.

I reinstalled x86/x64 2012, 2013, 2019 packages and tested the game for stability once again, before I wrote my previous message.

I followed it, I did all these steps several times during the last year on 2 different hardware configurations. Only my gfx card was the same. Those steps didn't help. I believe your solution is too trivial to be a silver bullet for this specific game. Because you didn't experience the DX12 crashes, you had something else and fixed it.

Considering driver version I mentioned - 23.5.1 - I also have AMD card. It's RX6600 8GB.

I wish I knew why. Because they probably played single player campaign, which is less taxing, therefore more stable, because they played the older version (people believe that crashes started after one of the updates), because they probably had more RAM/VRAM than an average player. because they had Win 11.,, I don't know.

But I do know that DX12 crashes are completely random. Sometimes the game works fine during 2 hours, sometimes it crashes after 10 minutes again and again. For example, on 1st of June it didn't crash within 5 hours. I wish I knew why. I mean I know why, I didn't do things that raise the possibility of crashes like, for example, playing coop missions. Which I do every Monday, because it's a daily challenge, and the game almost always crashes during them.

That's not saying much. I urge you to post your rig: both the hardware and the software side. CPU, RAM/XMP clocks, PSU.., OS edition/version, antivirus, firewall.,, Unique settings like SAM/resizable bar, MPO, ULPS, Freesync. Game mode, etc,,, In-game settings, preset, Vsync, fps limit, etc... Everything that might be helpful for other people.

You are going to reinstall windows to the C drive. After reinstall you'll need to reinstall the VC x86, and VCx64.

So I did clean install of Win 10 Pro x64 22H2, installed 23.5.1 AMD drivers and nothing else, installed Ubisoft Connect client and verified the game files, installed VC packages. Started to do my stability test. The game freezed/crashed after 12 minutes.

As expected clean Windows install doesn't help. Reinstalling of Windows is a terrible, terrible advice you shouldn't follow. It's just a waste of time.
