The only thread that I've found suitable for this was locked, so created a new one.
After starting the game, I have a bug - the loading screen, game menu and while in match (in match only HUD) flashes like an old TV from 60'ies - 70'ies. Once there was a notification that there might be problem with video settings, but don't know exactly what it can be.
Has anyone faced such problem? Are there any solutions to fix that? Can it be a problem of my OS (windows 10 / 64bit) ?
