Description

The error appeared first about two weeks ago (before latest update), but was quickly resolved through updating graphics card drivers and changing launcher parameter- memory allocator- to jemalloc.

Now with the new update, there are no new graphics card drivers, and switching memory allocator between the three available options do not help. Usually the crash happens before 5min, but rarely I have been able to play for about 20-30min. I have tried the following:

Verifying game files, clean reinstall of game and mods, reinstalling directx and visual C++, running windows system file check repair (DISM+SFC), switching memory allocator (as mentioned above), running launcher/game as administrator.

I've also tried different servers and with/without mods but same crash occurs.

Also attempted starting single player (Apex, Old Man) but crashed just after the starting text "Operation Safe Horizon has ended" and the screen switched to a picture with Blackfish helicopters and soldiers.

    Something went wrong just before the crash actually happened. I cannot see what the cause was.

    You could try switching to Profiling Branch, it does some things different, maybe you're lucky and that avoids the issue. But I don't know what the cause is so don't know for sure if that'd fix it.

    I've only tried it now a short time without any mods at all but seems to work so far (~2h without crash) ๐Ÿ™‚ Thanks!
