Trying everything imaginable since weeks now. Sometimes game just closes after some hours, sometimes it happens on every 2nd map.

intel i7 14000k / 4070 super / 32 gb / installed Game on SSD / updated and changed drivers with DDU, updated windows, checked game files with steam, monitored system with GPU Z and afterburner, disabled windows anti virus...

My System is a month old - had no problems in the beginning. Went through lots of settings for the game itself, nvidia control panel and windows 11 but nothing helped so far.

Happy to give more informations if needed, thanks.
