I've started playing FS again after couple of months and for some reason, I get flickering horizontal lines when framerate drops below 60. It's not that noticable during normal gameplay but still rather annoying. I figured it might have something to do with vsync but fiddling with the settings in both the launcher and Nvidia control panel did nothing.
I haven't done any significant changes to my setup after the last time I've played except getting a secondary monitor which I keep disabled when I play something.
Anyone ideas what might be causing the problem? I attached the log file but it looks perfectly normal for me, and I've used the same settings before without any issues.
