Without more specific info, here are some things to try:
Verify game files through Steam… corruption can cause a similar issue to what you are experiencing
Make 100% sure your system is patched OS and you are using a newer/newest GPU driver.
Dont know what settings you are using, but as a test, temporarily set your game to 1080p, 60fps framerate limited with every graphics setting to very low or disabled… See if this gets you past the problem spot… If it does then you have found ‘another’ graphic performance related issue and the workaround till the devs resolve it is to find the best stable config for your system by increasing the res, then fps limit (do not leave this unlimited) and toggling graphic quality settings…
i’ve forgot to check for corrupted/missing files before the post. There was indeed one corrupted and it seems to work now again. Thanks you’ve reminded me and sry for the unnecessary post in the end.
