Verify steam files, update graphic driver. Try to run the game in no sky mode. Sometimes game updates bring such "features" and a lot of people complain about it. Let's hope that WC will fix it.
Verified steam files like 5 times in the past 2 days, didn't change anything.
Runned the game in no-sky mode made it actually worse than it is without nomansky.
Drivers are up2date, my computer is pretty brand new bought it like 4 months ago all new parts.
So it's probably the game and not my hardware?
