Constant crashing and strange bug with motion blur

Was playing Diablo 4 today on my seasonal character, a rogue, when I crashed twice after opening the map and once opening settings after I got a strangely large amount of motion blur.

After this I scanned and repaired files and started playing again.

I was able to reproduce the motion blur by dodging whilst going up sone stairs, the bug persisted after exiting to character select and reloading. It only ever stopped after a full restart. Exit the application and relaunch.

Then on the next launch of the game I was doing a dungeon when after meeting a bunch of enemies and dashing into them I got the intense motion blur again. After killing the group I went into settings again and it immediately crashed.

After all crashes but the last when I relaunched the game I was put into a black loading screen which I had to just alt+f4 out of.

The game is currently unplayable (pretty much) for me so I will do a full clean install. I will update here if the issue persists or goes away.

Edit 1: after reinstall

Reinstalled the game, upon loading my seasonal rogue i still had the crazy motion blur, went into settings and it crashed.

Loaded it up a second time just to get the motion blur riding my horse to a dungeon. Crashed after going into settings. FC2D725E-A74A-4945-8B33-9ACEB2AE0E1C was the code.

Game is unplayable.

Edit 2: went back after last post because why not?

i completed 1 dungeon and after i used a portal to return back to kyovashad i had the motion blur again. Atleast i lasted 5-10 mins without it.

Check if your graphic card is applying any settings, that can make the game confused.
Nowadays theres alot of Graphic Card Drivers options to override application settings.

there shouldn’t be any graphic card settings interfering and the problem only occurs on d4, nothing else.

Yap, i understand your indignation.
But i am just trying to help :slight_smile:
What your Graphic Card is Nvidia or AMD? You can find any method to exclude D4 and try it?

Nvidia, don’t know what you mean by excluded d4.

Will probably just take a break from d4 for a bit

Can you try to enable in nVidia control panel → Help → Debug Mode and see if crashes still occur?

Your are using DLSS? If U disable it it works better?
If you are using try change the file for DLSS DLL to a recent one.
you can find it here: “tech power up . com / download / nvidia-dlss-dll/”
And copy the file to Diablo4 Folder

I am using DLAA, not sure if that makes much of a difference

I had similar issues to this and turned out to be an issue between windows 11 and my monitors (Not saying it is the cause in your case but it’s something worth looking at). My monitors are 144hz native but windows 11 was limiting to 60hz. Once I set windows to use my displays at 144hz the horrible motion blur/shadow in D4 (only game I was seeing this issue as well it’s worth noting) went away

I was able to play for 2 hours without any bugs or crashes. The only setting I changed was not using DLAA frame generation

Sounds more like a Shader compiling issue to me in all honesty as it doesn’t just apply a filter over the main camera it actually can crash you, which suggests that the shader itself could be mentioned in the Diablo IV directory under “_FenrisDebug.txt”

Read the log prior to you crashing, example… each time you exit out or the client crashes, head straight into that directory and open up the log file and scroll all the way to the bottom, read through it… also if you dont understand the output you could just copy/paste over to the technical support, or i may be able to find a way round it myself, but would need to see the actual logs first of course.
