Diablo 4 locking up randomly

So maybe I’m misunderstanding or perhaps you are but this was about the game freezing UNTIL you alt tab, then that would fix it. What you described sounds like a different problem.
If you did mean that if you alt-tab, then your game freezes up, I’d suspect it’s a bug in your current driver version, or some other software you’re running messing it up. I’m assuming you’re running the latest driver, and if so, you could try rolling it back to the previous version to rule that out. I’m just reaching for anything I can think of at this point though.

I changed multiple drivers over the months. Game sometimes freezes when i tab back into the game (not while playing) - my screen is frozen but i can hear it running and can click/move, quickly alt tabbing or pressing the windows button fixes it. Same thing happens in Battlefield 2042

Same here, but In my case, the app crashed after that.
I died in hard core mode because of this issue. For the time being, I don’t have the energy to play again.

Oh, that does sound like the same issue, just manifesting itself a bit differently. Still hearing the sounds normally but the frame rendering being ‘stuck’ sounds like the same problem. When I get a ‘normal’ performance drop, like when assets/stuff is loading, the music continues normally, but if I click or press a key to use an ability, I can’t hear the sound effect of that ability, like I could when I had enhanced sync enabled and had to alt-tab to fix it. Hopefully someone at Blizzard is paying attention to this. I was surprised that they fixed the ‘performance issues on high end machines’ so quick, but I’m just assuming that’s what fixed my terrible stuttering in maps with lightning. I’m guessing you’ve tweaked all the various graphics settings in game right? During beta, I had to run it at ‘medium’ settings because ‘ultra’ would run like garbage.

I never had performance issues during the betas and now after release. (5900X 32GB ram 4090 win11 22H2)

I have the feeling that this is some kind of windows problem since it started happening awhile ago (Its happening in BF2042 as well so its not a pure D4 issue)

I’ve played for about 30-45 min, and have had no freezes. It did seem that enhanced sync was turned on, although I never turned it on myself, it might have just been enabled by default!

After a long period, there does seem to be one freeze (I think it might be the vram dumping or something) but it recovers by itself, and doesn’t require an alt-tab. Could be network or something related, but otherwise its mostly fixed.

Had the same issues on 2042 and D4, tried everything, what helped the most is disabling any kind of Sync and future frame rendering.

I have the same softlock on Ps5, with no way out but going back out to home menu , closing and restarting the game. It seems to happen on random events like an NPC leaving my party, ann item dropping, opening the inventory, opening a town portal. Very annoying. Some days it never happens, and others it happens multiple times. Can’t send a crash report because the system doesn’t detect a crash.

Happy I found this, my setup is a little more Frankenstein, but the only issue so far is the freezing you have reported here. Game never completely locks up, just some play actions and all monsters freeze in their last action. I can even run around the map as long as the parts have been rendered, can even open and change settings, but no fix other then quit game and restart system. system start resets issue with locked account, if I start game without that will get the locked error.

On to the Frankenstein, running a 2020 5k imac with 10 core i9 and radeon pro 5700xt with 16gb vram. 128gb ram, no overcolocking.

AMD bootcamp drivers are too old for diablo 4 to run, there is a great site updating amd drivers for 5k imacs - boot camp drivers dot com.
They have 2 versions off the amd software, tried them both on various settings. Card performance is great in all resolutions from 4k down to 1920x1080, 80-100 fps ans shows excellent or optimal on high setting.

Still, nothing Ive tried is fixing this weird partial freeze. Trying to go through the fenric reports but Im not that savvy Maybe Ill post one in another reply.

Almost every other crash thread or online advice represents a full crash or freeze, this is the first thread Ive seen describing my issue,

I realize it could be driver or bios weirdness, but now that Im seeing others with windows only and newest drivers have this issue Im still trying to resolve, Id probably be at level 80 instead of 42 because Im playing 1/2 the time, and freezing/trying to fix the issue… blarg Thanks for sharing - BSR

Can concur Alt-Tab switching windows/apps is causing ‘tear/lag’ of game.
Repeat Alt-Tab to solve crash.

However, this also means the the game reaction time is affected negatively too, sometimes the hero dies during combat due to suddent ‘tear/lag’ after alt-tab.

Read somewhere window (fullmode) unavailable option in D4 (present in D3) is conflicting with Alt-Tab. … Sighz.

Due to lack of QoL , like events timer / game mode (aka prevents alt-tab / social elements missing within game, hence need to alt-tab to go alternate sites (e.g. discord) really spoils the immersive game-stay-in-game EXPERience!

This is still an issue and its happening really often. The only workaround i found is to play the game in Windowed mode.

In Windowed Fullscreen my game still freezes when i alt tab to check a build or something else, sometimes when i press buttons or click with my mouse while the screen is frozen it opens “This PC” where i can see my disk drives.
