Found a fix finally, installed DayZ Exp, copied all from the document file to the normal DayZ, launched it and it worked.

I did now, sadly still nothing. Games just doesn't respond gets to 99% ram and crashes...

Yeah i have Nvidia GPU on both machines, but i manually installed them. I dont even have geforce experience installed.

I reinstalled windows to windows 11 now, game still wont start. Bought a laptop yesterday, installed it on the laptop and still wont work. Is it somehow related to my steam account? I have no clue what else to do :/

The game not only uses 99% ram now, it uses 99% cpu as well

Still black screen :/

I do not know, the settings have been reseted. I can not get into the game to check it.

I uninstall windows 10 and installed windows 11 i thought maybe it would fix that, but it did not

Yes i did that as well

I tried that but it didn't work, tried it again now and still the same result. Game eventually goes to 99% ram usage and crashes. PC Specs: Ryzen 7 5800X, RTX 3080 TI, 32 GB DDR4 3600MHZ
